As an Engineering Professional you need a Mission - Steve Mackay - You’ve probably heard (with some irritation) the expression: ‘Get a life’. Well; research shows that if you want a longer, healthier and more fulfilled life; you should establish a purpose to your life with clear (achievable) goals. This not only applies to when you are in retirement but as an engineering professional working today. When we are younger we are often overwhelmed with short term goals – getting a career under way; establishing a family; bringing up your kids; dealing with health issues and those of your family and simply paying the bills. As you move into your mature phase of your career and life; there is often more time to contemplate the future and assess what you are currently doing. And to think about goals.

Australia Wind beats New Coal in the World’s Second-Largest Coal Exporter - Unsubsidised renewable energy is now cheaper than electricity from new-build coal- and gas-fired power stations in Australia, according to new analysis from research firm Bloomberg New Energy Finance. This new ranking of Australia’s energy resources is the product of BNEF’s Sydney analysis team, which comprehensively modelled the cost of generating electricity in Australia from different sources. The study shows that electricity can be supplied from a new wind farm at a cost of AUD 80/MWh (USD 83), compared to AUD 143/MWh from a new coal plant or AUD 116/MWh from a new baseload gas plant, including the cost of emissions under the Gillard government’s carbon pricing scheme. However even without a carbon price (the most efficient way to reduce economy-wide emissions) wind energy is 14% cheaper than new coal and 18% cheaper than new gas. “The perception that fossil fuels are cheap and renewables are expensive is now out of date”, said Michael Liebreich, chief executive of Bloomberg New Energy Finance. “The fact that wind power is now cheaper than coal and gas in a country with some of the world’s best fossil fuel resources shows that clean energy is a game changer which promises to turn the economics of power systems on its head,” he said.

Safety Instrumented Systems: Design, Analysis, and Justification 2nd Edition - Paul Gruhn, P.E., CFSE and Harry L. Cheddie, P.Eng., CFSE - This revised best-seller is ideal for instrumentation and control system engineers in the process industries who are responsible for designing, installing, and maintaining safety instrumented systems. Engineers, managers, technicians, and sales professionals employed by end users, engineering firms, systems integrators, and consultants can all benefit from the material presented here. Safety Instrumented Systems: Design, Analysis, and Justification, 2nd Edition addresses the increased realization that today’s engineering systems—and the computers used to control them—are capable of large-scale destruction. When even a single accident could be disastrous, the luxury of learning from experience no longer exists. This book is a practical how-to text on the analysis, design, application and installation of safety instrumented systems.


ICEbus - Information on any of the 26 different bus systems in use in the area of Instrumentation and Control.

Foundation Fieldbus, Fourth Edition - Ian Verhappen and Augusto Pereira

The fourth edition of Foundation Fieldbus significantly expands the subject matter of the earlier editions of this popular book not only to help you stay current with this evolving technology but to also enhance your understanding of Fieldbus. This edition provides in-depth coverage on Fieldbus communications and configuration, including calculation of macrocycle for Control-In-Field and in the Host system and how the different forms of communication on the H1 network work with each other to make Control-In-Field possible, including the use of these different methods to optimise network bandwidth.

Part of the field network evolutionary process includes a need to understand better how the changes in Electronic Device Description Language (EDDL), Field Device Tool (FDT), and Field Device Integration (FDI) will affect the way Fieldbus and other networks work together with asset management systems of the future, and your interaction with field devices.

More comprehensive step-by-step procedures are discussed for each stage of a typical FF installation: Inspection and electric commissioning to ensure cable integrity, H1 Network commissioning, configuration, and communications tests in the segments and the spurs. Several new photographs and explanations help emphasize the proper installation procedures so you can quickly identify and prevent potential problems when installing Fieldbus systems.

The contents of the entire book are then put to use with a full sample network design. The example is based on a typical simplified distillation tower and includes sample calculations/documentation-based.

The fourth edition explains Foundation Fieldbus in a convenient, easy-to-understand way, regardless of your level of experience; a novice wanting to learn what FF is all about or an experienced user looking for a few more tips and a single handy reference.

Ethernet Will Outpace Fieldbus in Industrial Automation Sector, Study Shows - A new study by IMS Research (now part of IHS Inc.) estimates that fieldbus protocols accounted for 75 percent of new industrial automation component network connections in 2011. This is projected to fall to 69 percent in 2016. New network connections using fieldbus protocols are still some way ahead of Ethernet, yet growth of Ethernet connections is expected to be considerably higher to 2016 - from FlowControl Network.  

2013 Training Schedule for PROFIBUS and PROFINET - Eighteen free training classes in the USA are scheduled for 2013. There are two different curricula: PROFIBUS and PROFINET. Specific dates and venues are selected at least 30 days prior to the class.

Analysers

ICEweb's Analyser pages cover many types of analysers plus their associated sample systems.

How to Keep Analysers Cool in the Field - Anthony Leong and Martin Hess - Field-based process analysers are often sited in remote environments where they need protecting against harsh environmental conditions, and high daytime temperatures. For optimum performance and reliability, their electronics and sample conditioning systems must be maintained within prescribed temperature limits, requiring that the environmental protection shelter is well insulated and incorporates some form of cooling. Most analyser shelters currently use air conditioning (AC) systems to protect against high temperatures. These are expensive - especially if they need to be explosion-proof - and can account for a high percentage of the capital, energy and maintenance costs of a typical oil or gas analyser installation. Furthermore, they do not easily scale down to suit small shelters, and their performance decreases by as much as two thirds at high ambient temperatures. One recent trend is to employ passive cooling technology. Originally developed for pipeline instrumentation shelters in remote desert locations without an electricity supply, passive cooling systems (PCSs) have been deployed successfully over the past decade - from the excellent Pacetoday.

Explosion Protection for Process Analysis - Safe operation up to the explosion limit - Jürgen Poidl and Helmut Schulz - Gas analysers are used for the continuous on line measurement of the composition of process flows in chemical production systems. These measurements provide support to key process functions of controlling and monitoring the temperature, humidity, and chemical composition of gases and liquids.  In some cases, commercial considerations and demands are resulting in the operation of production processes in chemical plants increasingly close to the explosion limit. It is therefore essential that the explosion- protected gas analysers used for monitoring the explosion limit continuously supply the necessary and reliable data to the process control systems. Using the special safety systems it is possible to operate gas analysers, the electrical equipment and the safety devices even when the process conditions are close to the limit - from Stahl.

International Standard IEC 61285 – Industrial Process Control Safety of Analyser Houses - Process analysers measure the characteristics of a process stream continuously and automatically. The process sample is introduced automatically and the system is designed for unattended operation and minimal maintenance. This document is designed to set forth minimum safety requirements for typical analyser houses (AHs). You will have to purchase this standard.

Gas Chromatography Troubleshooting Guide - A useful guide for seeking out Gas Chromatograph faults - from msp.

Encyclopedia of Analytical Chemistry - The highly-acclaimed Encyclopedia of Analytical Chemistry provides a much-needed professional level reference work for the 21st Century. The Encyclopedia is the most comprehensive analytical chemistry reference available, covering all aspects from theory and instrumentation through to applications and techniques. You have to pay to access the content.

Chromatography  - The Basics - Chromatography is usually introduced as a technique for separating and/or identifying the components in a mixture. The basic principle is that components in a mixture have different tendencies to adsorb onto a surface or dissolve in a solvent. It is a powerful method in industry, where it is used on a large scale to separate and purify the intermediates and products in various syntheses - from the Royal Society of Chemistry.

Burner Management Systems

Thanks to our sponsor Invensys Triconex ICEweb's Burner Management System page has around 70 fantastic technical links , many which are new, to assist you if you work in this area.

Safety Controls and Burner Management Systems (BMS) on Direct-Fired Multiple Burner Heaters - Although some detailed and prescriptive guidelines have been around for many years, the rate and degree of adoption varies significantly within the industry. Most operating companies have their own “standard”, which may still vary from facility to facility. In addition to this, for each installation, it is not unusual for adjacent heaters built two years apart to have a different BMS design, simply because different engineering contractors built them. With increasing government legislation and regulations as well as mounting lawsuits for accidents in which applicable codes and guidelines have not been adhered to, it is important to review the BMS requirements for both existing and new heater installations - from Onquest.


Cables

Loads of links to cable information can be found on this page.

Why Should You Specify Cable Glands? - How often have we heard:- "We don't specify Cable Glands, as long as they have the relevant certification then it must be fit for purpose. We leave it to contractor to sort out. We are too busy concentrating on the high value, long lead time items to bother about such an insignificant value product. In a recent paper presented at the Hazard Ex conference by a Senior Manager of CENELEC Standards Inspections, it was stated, "Resources should be directed at eliminating the following common faults; Unauthorised modifications, badly made-off or unsuitable cable entry devices and Corrosion. It went on to say that out of these three factors, the most common fault was bad installation of Cable Glands. The paper was specifically referring to maintenance procedures, but this could equally be applied to new installations. Incorrect specification and installation combined with the lack of ability to inspect the Cable Gland in it's operable condition can cause equipment failure and corrosion of cable armour and braid. The safety risks inherent in this is incalculable, as is the consequential loss of production. This statement alone should be enough reason why specification of Cable Glands is an important decision. Just relying on the fact that a Cable Gland has a certificate "fit for purpose" is not enough - from Hawke International.

Fantastic links covering Diagnostic Tools for Control Valves, Valve Sizing, Control Valve Handbooks, Self Operated Regulators, Control Valve Noise Calculation and Prediction, , Positioners, Selection and Application, Maintenance and a mass of other really useful Links to Articles on Control Valves.

Selecting a Control Valve- Fluid velocity in a control valve is a key parameter that must be considered when sizing and selecting a control valve. High fluid velocities can lead to erosion damage, trim wear, trim component failure, vibration and high noise levels. Therefore, it is vital to design for valve velocities within acceptable limits so that these problems are avoided. This paper addresses these issues - from Masoneilan.

Valve Sizing & Selection Technical Reference - This is an excellent resource! -A Control Valve performs a special task, controlling the flow of fluids so a process variable such as fluid pressure, fluid level or temperature can be controlled.  In addition to controlling the flow, a control valve may be used to shut off flow. A control valve may be defined as a valve with a powered actuator that responds to an external signal.  The signal usually comes from a controller.  The controller and valve together form a basic control loop.  The control valve is seldom full open or closed but in an intermediate position controlling the flow of fluid through the valve.  In this dynamic service condition, the valve must withstand the erosive effects of the flowing fluid while maintaining an accurate position to maintain the process variable. A Control Valve will perform these tasks satisfactorily if it is sized correctly for the flowing and shut-off conditions.  The valve sizing process determines the required CV, the required FL, Flow Velocities, Flow Noise and the appropriate Actuator Size - from Warren Controls.

Commonly Asked Questions about Control Valves - This list of questions will be very useful to Graduate Instrument Engineers - from Mitech

Standards for Control Valve Seat Leakage - This document details the various leakage classes - from Mitech.

Video - Sliding-Stem Control Valve Packing – This video gives an excellent description on how spring loaded packing works – from BTC Instrumentation.

Split Range Control Valves - This tutorial details just what split range is along with some examples - from Contek systems.

Control Valve Noise - Without meaningful standards being adopted in environmental control (to which also the prevention of valve noise appertains), chemical or petrochemical plants would today not be approved. For this reason, “acoustic planning” for the dominating noise sources is categorically required. This applies particularly for compressors, process ovens, cooling fans and not least for control valves and pipelines. In order to keep the emitted sound power within limits quite extensive corrective measures are required. Since noise attenuation measures within a severe costs/benefit analysis must also make sense, one will only implement noise reducing precautions where it is absolutely necessary. As a result, the competitiveness of the whole enterprise, who wants to construct their plant near a residential area, may be questioned if the permissible sound power level near the plant boundaries has to be especially low.

Control Valve Accessories - The following chapter deals with the most important accessories of pneumatic actuators designated in general usage as auxiliary devices, although this definition inadequately describes the importance of these devices. It is nevertheless the “accessory” which often enables the success of certain applications and is vital for the action and performance of a final control element. Positioners, converters, limit switches, position transmitters, solenoid valves and lockup valves are transfer elements designed to adapt pneumatic control valves to the requirements of industrial plants. Supply pressure regulators and air reducing stations are used to supply the pneumatic instruments with compressed air.

Inherent Rangeability - Ideally the open-loop gain remains constant independent of the position of the valve in a closed-loop control system. Unfortunately, this condition is only achieved in rare cases. Every user has already experienced a situation where a control valve at higher travel positions is completely stable, yet permanent oscillations occur at small travel positions. This is caused by a higher gain of the valve and a steeper slope of the valve characteristic. In order to simplify the application and the selection of control valves for the control specialist, certain  boundary values for the slope of the inherent characteristic have been set. In this way, the permissible slope tolerance is exceeded if the inclination of the straight line which connects two neighbouring measured values (e.g. points 5 % and 10 %), is more than 2:1 or less than 0.5:1. This rule applies for valve characteristics which the control valve manufacturer has specified for the same travel positions in its literature.

Top Ten Alarming Blunders - Proper Alarm Methods Improve Safety, the Environment, and Plant Profitability - Kevin Brown - Ineffective alarm systems pose a serious risk to safety, the environment, and plant profitability. Too often, alarm system effectiveness is unknowingly undermined by poorly configured alarms. Static alarm settings cannot adapt to dynamic plant conditions, and many other nuisances result in alarm floods that overwhelm operators when they instead need concise direction. Alarm systems are the primary tool for identifying abnormal situations and helping plant personnel take timely, appropriate action to move their processes back to operational targets. For operators considering undertaking an alarm management program, taking the time to examine common alarming blunders is important to ensure steps are taken to avoid them - from InTech.

Corrosion

Need to know about a corrosion issue? You are likely to find an answer in these pages.

Beginners Guide to Corrosion - Bill Nimmo and Gareth Hinds - This document gives an introduction to corrosion and its control in non-technical terms - from NPL.

Corrosion Control And Treatment Manual - This manual provides guidelines for the control of corrosion of materials in facilities, systems, and equipment at the John F. Kennedy Space Center (KSC), Florida. It is very comprehensive – from NASA.

Corrosion of Duplex Stainless Steels in Seawater - Bengt Wallén - In the following paper a review of most types of corrosion occurring in seawater applications is given. With just a few exceptions, only tests using real seawater have been taken into consideration. Whenever possible, the behaviour of superduplex steels is compared with that of super austenitic steels – from Avesta Sheffield.

Pitting and Crevice Corrosion of Offshore Stainless Steel Tubing - Gerhard Schiroky and Anibal Dam - Oil and gas platforms regularly use stainless steel tubing in process instrumentation and sensing, as well as in chemical inhibition, hydraulic lines, impulse lines, and utility applications, over a wide range of temperatures, flows, and pressures. Corrosion of 316 stainless steel tubing has been observed in offshore applications around the world. Corrosion is a serious development that can lead to perforations of the tubing wall and the escape, under pressure, of highly flammable chemicals. The two prevalent forms of localized corrosion are pitting, often readily recognizable, and crevice, which can be more difficult to see. Many factors contribute to the onset of localized corrosion - from the excellent offshore magazine.


Condition Monitoring

Data Loggers

There are numerous Data Logger technical papers and articles in this updated page thanks to our valued sponsor HINCO.

Using Data Loggers Beyond Equipment Scheduling - Brenden Millstein - While data loggers are a great tool for identifying equipment-scheduling opportunities in buildings, their usefulness far exceeds just that one function. This paper discusses how the use of inexpensive data loggers and some spreadsheet analysis can provide all the evidence needed to make powerful building-specific cases for saving money by replacing failed air-handler economizers. It also describes how information from data loggers can be used to accurately calculate the energy savings that can be realized from variable frequency drives (VFDs) on pumps and fans, supply air resets, and boiler lockouts.

Analyzing Air Handling  Unit Efficiency - Michael Rosenberg - Operating a heating, ventilation and air conditioning (HVAC) system at optimum efficiency in a commercial setting is complicated, to say the least. There is a very real chance that any number of setpoints, levels, and feedbacks at boilers, chillers, pumps, fans, air delivery components and more can cause costly inefficiencies. This 20-page guide, Analyzing Air Handling Unit Efficiency with Data Loggers, explores the air handling systems of an office building to illustrate how data loggers can be used to help optimize their performance. The guide provides 13 best practices for improving air handler efficiency and reducing costs, while maintaining a comfortable working environment for building occupants.

Finding Hidden Energy Waste with Data Loggers - 8 Cost Saving Opportunities - Paul H. Stiller - The first step to reducing building energy costs is identifying energy waste. Statistics on utility bills or name plates on equipment, while useful, are not enough to identify what practices and equipment are contributing to high energy use. Portable data loggers can be used to obtain critical energy use information in a wide range of commercial building types – from manufacturing plants to office buildings. This 12-page best practices guide, Finding Hidden Energy Waste with Data Loggers, describes the data logging equipment you need to obtain information on energy consumption and environmental conditions in commercial buildings. It covers eight common forms of energy waste, and provides an overview of how to gather and analyze data and calculate savings for each opportunity.  

Guide to Choosing Occupancy and Light On-Off Data Loggers – 5 Important Considerations - In 2010, the residential and commercial sectors in the United States used  approximately 499 billion kilowatt-hours (kWh) of electricity for lighting, equal to  13% of all electricity used nationwide (U.S. Energy Information Administration).  In commercial buildings alone, 35% of all energy cost is attributed to lighting  (2005 Buildings Energy Data Book, U.S. Department of Energy). Often the first step in any new facilities project is convincing decision makers that a project is worthwhile and will pay off. Before committing to costly equipment upgrades and making changes to electrical systems by installing hard-wired light sensors, it’s a good idea to first acquire data on room occupancy and lighting use in a facility to determine where best to implement permanent changes. Portable occupancy and light on/off data loggers are the solution. They are battery-powered, matchbox-sized devices that can be easily mounted on ceilings, light fixtures, and stairwells – anywhere data are needed.

Playing it Safe - How Information Management Technology is essential to meet more stringent Process Safety and Regulatory Compliance - Process Safety and Compliance are universal issues across all the world’s plant industries and individual regulatory authorities are increasingly collaborating to share ideas and to normalise globally consistent, best-practice requirements. These authorities have recognised the potential of Information Management technologies for supporting safe and compliant operations and we can expect to see their use progressively being encouraged, expected and mandated as regulations advance. But the issue is not only one of maintaining regulatory compliance. The US Centre for Chemical Safety claims that an average offshore incident costs an Owner Operator $80 million, so there is a serious economic incentive involved as well. This paper examines current capabilities, opportunities and likely future directions in the application of technology. For convenience, reference will be made to new offshore regulations emerging in the USA, as these are likely to set benchmarks for global regulatory standardisation.

Top Ten Instrumentation Headaches - How ‘Visual Engineering’ is solving Designers’ and Engineers’ issues – across the industry - Control systems play a vital role in all aspects of modern living,  from helping us drive our cars, to safely running large petrochemical complexes and power stations. According to recent industry research, instrumentation is the biggest spend item in any plant. Capital expenditure on buying new instruments in 2010 was estimated at $5bn, with maintenance and operation costs projected to reach $4.9bn. But much of this cost is unnecessary. It arises because the technology used to plan and design instrumentation and control systems has often been developed with little regard for engineers’ and designers’ natural working methods. Procedures that can be perfectly straightforward if represented graphically rerouting a wire, for example, or segregating cables are all too often dependent on manual, tabular data input, which is time-consuming, expensive, and prone to error. AVEVA spoke  to instrumentation and control experts across the industry and identified no less than ten key areas where other vendors’ instrumentation design technologies fail to meet engineers’ and designers’ requirements. These are the top ten headaches that the engineers and designers face on a daily basis. The good news is that companies can avoid these headaches entirely by deploying the ‘visual engineering’ approach at the heart of AVEVAs field-proven instrumentation solution.

Shift Handover -The Importance of Continuity - Shift handover has been shown to be a common source of revenue loss and safety incidents in plant operation. Both economic and regulatory pressures demand substantial improvement in the shift handover process. Every engineer knows that discontinuities are invariably a source of weakness, whether in physical structures or in continuous processes. This is particularly true in the case of shift handover but, whereas physical discontinuities may be easy to identify and remove, discontinuities in working procedures can be far more difficult. It has long been recognised in the plant industries that the discontinuities of shift handover are among the most common and potentially serious sources of problems. These can range from minor impacts on operational efficiency to the most serious safety incidents; all incur corresponding levels of economic cost. The root of the issue is the transfer of information from outgoing to incoming shift teams. This paper looks into the problems arising and describes how the latest information management technology can be used to overcome them.

Sustainable Energy Management - Putting Information Assets to Work in the Process Industries - This paper outlines the challenges facing process plant operators in implementing effective Energy Management strategies. It describes how these challenges may be overcome through the use of currently available Information Management technologies supported by a comprehensive, Service-Oriented Architecture (SOA). Information Management technology can overcome the technical barriers to effective Energy Management and provide the means to harness an enterprise’s extensive, but often under-exploited, information assets. Such capability supports the key elements of a sustainable, long-term Energy Management programme: best practice methodology and an integrated framework to address its information requirements. Rather than being just a short-term initiative with a single objective, this type of programme constitutes a substantial step on the road to implementing a comprehensive Operations Integrity Management strategy to deliver enterprise-wide business benefits. An Energy Information Management strategy can thus lead to more extensive and sustained optimisation of all aspects of asset operation.

A Shocking Waste of Money - Eight Reasons Why Electrical Design Costs More Than it Should - Electrical engineering and design is one of the most complex and demanding challenges facing EPCs and shipbuilders, in new builds, in-plant projects, and marine refit. Recent capital expenditure on electrical engineering and design has been estimated to reach $3 billion in the hydrocarbon plant industry alone. But should we be shocked by this figure? Surely such a complex discipline necessarily comes with a high price tag? Expense is inevitable, certainly. But wastefulness is unforgivable. Unfortunately, the technology used to plan and design electrical systems, just like that used to design instrumentation and control systems, is often just that – wasteful. Because it has been developed with little regard for engineers’ and designers’ natural working methods, it results in cumbersome and error-prone methods of handling data, and prevents users from making effective technical use of the natural synergies that exist between many activities.

New Method for Accurate High Reynolds Metering uses Water Calibration for Significant Cost Savings - Jonathan Hollist and Nick Voss - Cone meters have been shown to be an accurate measuring device for various flow applications. In order to maintain accuracy, Cone meters need to be calibrated to determine the discharge coefficient (Cd). The Cd often changes with Reynolds number. The same meter can have a different Cd for gas applications (high Reynolds numbers) than for liquid applications (low Reynolds numbers). Therefore a Cone meter needs to be calibrated over the entire range of Reynolds numbers for its specific application. In order to reach the high Reynolds numbers in most gas applications calibration need to be done in a gas lab. This often is verily costly and time consuming. To save time and money, accuracy is often sacrificed and a Cone meter slated for a gas application is calibrated in the manufacturer’s water facility. McCrometer has developed a method that can predict the Cd at high Reynolds numbers based on a water calibration at small Reynolds numbers. This paper discusses the accuracy of this method.
Pipeline Crude Pumping Station Solves Flow Measurement Problem with V-Cone Meter - Nick Voss - A regional light crude pipeline operator in the mountain states of the U.S. was looking for an economical, accurate method to measure crude inventory flow within its pumping stations. The pipeline operator specializes in transporting partially processed crude to other lines or main terminals. Accurate flow measurement is essential to the cost-effective operation of pipelines. While highly precise, and often expensive, flow meters are required to perform custody-transfer measurements for payment purposes, there are also intermediate process measurement points within pumping stations, for example, that can be served with less expensive technology.
Custody Transfer Flow Measurement with New Technologies - Stephen A. Ifft - New technologies can often bring advances to the operational processes within many industries. These advances can improve the overall production of a facility with better performance, better reliability, and lower costs. Obstacles exist, however, to the introduction and use of these new technologies. The natural gas industry has such obstacles, particularly with the use of new technology for custody transfer flow measurement. Paper standards from international organizations like the International Organization for Standardization, the American Petroleum Institute and the American Gas Association are examples of these obstacles. While these paper standards serve to protect and guide companies in their use of technology, they prevent the introduction of new and often better technology. A reform is underway in the natural gas industry to allow companies to take advantage of newer technologies that were not accessible before. This will hopefully redefine the phrase “approved for custody transfer measurement.” This phrase has been used incorrectly around the world for decades since none of the organizations listed above actually approve meters for custody transfer measurement. If companies are to reap the benefits of newer and better technology, the industry must continue to reform the existing paper standards that exclude every technology but those that are decades old. As new technologies become available, the industry must have procedures ready for evaluating their possible benefits and detriments. Without these procedures, the advances of the modern world will be overlooked. McCrometer Inc. is a manufacturer of flow measurement devices, including the V-Cone differential pressure flowmeter. McCrometer has first-hand knowledge of the obstacles to bringing a new technology to the natural gas market. This paper explains how one new technology has been used successfully in custody transfer flow measurement applications even without “custody transfer approval”. 
Self-Conditioning Flow Meter Solves Measurement Challenges for LNG Processing and Distribution - Nick Voss - The Challenge - Converting natural gas to its liquefied LNG state reduces its volume by 600 percent. This reduction in volume facilitates transport by ship, export and distribution. The natural gas is first cooled to -260◦F (-162.2◦C), which condenses the fluid into the liquefied state. Flow is then measured again several times during transportation, storage, regasification and distribution through pipelines to the end users. The liquefaction process takes place in hazardous, space-constrained facilities. LNG processing, transportation, storage and distribution require a flow meter that is rugged, dependable, simple to install and suitable for use in potentially explosive environments. Flow meter technologies with moving parts or those requiring complex installation, or frequent recalibration and other maintenance represent potential safety issues, accuracy problems and added operating costs that burden production and refinery operations.

A New Paradigm for Thermal Dispersion Mass Flowmeters - John G. Olin - The ASME Standard and Recent Technology Advances - Since the publication of the American Society of Mechanical Engineers (ASME) standard on thermal dispersion mass flowmeters in 2011, there have been major advancements in the technology. A review of that standard and a discussion of technology advancements provide the background to understanding ground breaking innovations in sensor design. That, along with a comprehensive algorithm facilitated by current hyper-fast microprocessors, has created a new paradigm for the measurement of the mass flowrate of gases by means of thermal dispersion technology - from Sierra Instruments.

Thermal Dispersion Mass Flow Measurement Handbook - Accurate mass flow measurement of gas is difficult to obtain. Thermal mass flow technology is a method of gas flow measurement that does not require correction for changes in process temperature or pressure. Thermal mass flow technology also has a benefit of measurement at low velocities and greater turndown capabilities than those obtainable with other gas flow measurement devices.

Tracking Natural Gas with Flowmeters - Wayne Shannon - Thermal mass flowmeters provide advantages over other options for metering the consumption of natural gas by individual combustion units throughout the facility.

Measuring Flare Gas within the European Union Emissions Trading Scheme - Simon Harwood and Jack Koeken, Sr - Prior to the European Union Emissions Trading Scheme, the measurement of flare gas on oil and gas production facilities in the North Sea was driven mainly by statutory regulations that required operators to simply report emissions to the Environment Agency. Consequently, there was never an economic incentive to install metering equipment. Importantly, depending on the Industry and size of the facility, the Trading Scheme stipulates different levels of accuracy for the instrumentation used to measure both fuel gas and flare gas. For the oil and gas industry, flow meters used to report emissions from flares fall within the Tier 3 accuracy level which, means they must have a degree of uncertainty (accuracy) better than ±7.5 percent of the measured value - from Fluid Components.


Ultrasonic Flowmeters

Thanks to ICEweb Sponsor Zedflo our Ultrasonic Flow Metering page has been updated with new links, these include:

Clamp-on Ultrasonic Flowmeters - How they Measure Up - Clamp-on ultrasonic flowmeters – portable or permanent – are valuable tools for helping district energy providers, building owners and managers and others measure and manage their system performance in a number of ways. These units provide the baseline and load profile information needed to effectively optimize system efficiency and reduce energy consumption – and costs - from Siemens.

Are there Differences between Clamp-On Ultrasonic Meters Used for Onshore Purposes and Those Used for Offshore Projects? - Leslie Bottoms - While the basic technology used is the same for onshore and offshore projects, there are some differences between clamp-on ultrasonic meters in these applications. Offshore environmental conditions require a higher level of protection from the elements. The main concern with instrumentation when used offshore is the constant exposure to salt air and sea spray. This combination can easily corrode housings and cables which are exposed to the elements all day, everyday. A typical onshore application may involve temperature swings from 20 to 110 degrees F, but in most cases, the instruments used in these locations are generally protected from the sun and rain by sheds or some form of additional shelter. However, when located offshore, protection is limited to the instrument enclosure, due to size and weight limitations. In addition, temperatures are often exceeded at both ends of the scale.


Fire and Gas

Technical Papers covering many aspects of Fire and Gas Engineering. Thanks to Honeywell Analytics this page has been extensively re-modelled with many new links added.

Honeywell Analytics Gas Book - This updated handbook is intended to offer a simple guide to anyone considering the use of gas detection equipment. It provides an explanation of both the principles involved and the instrumentation needed for satisfactory protection of personnel, plant and environment. The aim has been to answer as many as possible of the most commonly asked questions about the selection and use of industrial gas detection equipment.

Fire and Explosion Guidance Part 0: Fire and Explosion Hazard Management - The updated Fire and Explosion Guidance has been prepared to encourage an integrated approach to the management of Fires and Explosions. As such, it complements the Safety Case and should help those persons with responsibilities for the safe design, construction and operation of installations to manage fire and explosion hazards- from Logical Software.

Fire and Explosion Guidance Part 1: Avoidance and Mitigation of Explosions - The primary objective of this document is to offer guidance on practices and methodologies which can lead to a reduction in risk to life, the environment and the integrity of offshore facilities exposed to the explosion hazards - from Logical Software.

Fire and Explosion Guidance Part 2: Avoidance and Mitigation of Fires - The primary objective of this document is to offer guidance on practices and methodologies which can lead to a reduction in risk to life, the environment and the integrity of offshore facilities exposed to fire hazards - from Logical Software.

Simplified Approaches to Fire and Explosion Engineering - Steve Walker, Brian Corr, Vincent Tam (BP), Justin Bucknell and Pat O’Connor - Recent and proposed large developments in deep water and the use of hub platforms with high throughputs in the Gulf of Mexico have raised awareness of the profile of fire and explosion safety assessments for new and existing installations. In response to these developments BP has developed new guidelines in Fire and Explosion Engineering described in this paper. The guidelines give useful, practical advice for the Structural and  Process engineering disciplines at a level appropriate for direct use in a project environment. In view of the maturity of the subject matter the focus is on code based and simpler methods of analysis. The approach is compatible with API RP2A and recommends two levels of explosion design  overpressures by analogy with earthquake assessment representing ‘Design Level’ and ‘Ductility Level’ events. The ‘Design Level’ explosion tests the installation against more severe performance standards appropriate to the higher frequency events. Three levels of analysis are defined for use in fire and explosion assessment. These are, ‘Screening Analysis’, linear elastic ‘Design Level’ analysis and non-linear ‘Ultimate Strength’ analysis. Acceptable inputs to these levels of analysis are defined.  The emphasis of this paper is on simple linear analysis methods for the evaluation of a structure during the first level of assessment. The Guidance is to be used as a basis document for the new proposed API RP on Fire and Blast - from Logical Software.  

European Test Procedures For the Functionality of Cables Under Effects of Fire - Since the year 2000 there is a European test procedure regarding the functionality of cables in case of fire - EN 50200. This test procedure in its latest version of 2006 is leading to the fire protection classifications PH 15, PH 30, PH 60, PH 90 and PH 120. But for the practice this test procedure is insufficient. The European standard EN 50200 is applied for cables with a diameter of up to 20 millimetre. For larger cable diameters a similar test procedure had been developed in parallel to the EN 50200. This procedure is called EN 50362:2003 - from Dätwyler Cables.

NEMA Publishes NEMA SB 13-2012 Guide for Proper Use of Smoke Detectors in Duct Applications - This updated guide, aligned with current codes and standards, provides technical information on basic fire alarm systems with a focus on early warning smoke detection devices installed in duct applications. Duct-mounted smoke detectors are designed to provide a specific type of protection that cannot be duplicated by any other type of system. However, there has been a tendency to misapply these devices by attempting to use them as a substitute for an early warning smoke detection system. This fact, coupled with new methods of detecting smoke in ducts, has prompted the writing of this industry guide. NEMA SB 13-2012 is available for download at no charge.

Explosion Protection for Process Analysis - Safe operation up to the explosion limit - Jürgen Poidl and Helmut Schulz - Gas analysers are used for the continuous on line measurement of the composition of process flows in chemical production systems. These measurements provide support to key process functions of controlling and monitoring the temperature, humidity, and chemical composition of gases and liquids.  In some cases, commercial considerations and demands are resulting in the operation of production processes in chemical plants increasingly close to the explosion limit. It is therefore essential that the explosion- protected gas analysers used for monitoring the explosion limit continuously supply the necessary and reliable data to the process control systems. Using the special safety systems it is possible to operate gas analysers, the electrical equipment and the safety devices even when the process conditions are close to the limit - from Stahl.

Maintaining Installations In Hazardous Areas - Thomas Klatt and Andreas Hennecke  - Flameproof enclosure (Ex d) and intrinsic safety (Ex i) are very common equipment protection methods in Process Automation.  One reason to use Exd is the amount of energy which could not be provided via Exi. This disadvantage has gone with the introduction of intrinsically safe, dynamic methods of arc prevention such as DART or Power-i. This white paper shows that when using intrinsic safety, installation, maintenance and inspection costs will be reduced.  This paper addresses decision makers and professionals responsible for automation systems in hazardous areas. A good understanding of the principles of explosion protection is required - from PEPPERL+FUCHS.

Hazardous Areas Technical Guide - This publication provides a brief overview of the essential aspects of explosion protection. Ultimately, safety in a potentially explosive atmosphere is a team effort. Manufacturers have a responsibility to ensure only safe equipment is placed on the market. Installers must follow the instructions provided and use the equipment only for its intended purpose. Finally, the user has a duty to inspect and maintain the equipment in a safe working order - from Warom.

Equipment Protection Level (EPL) - EN 60079-14 standard of March 2010 introduced a method for risk assessment that considers the equipment levels of protection (EPL). EPLs were introduced to allow an alternative approach to the methods currently used for the selection of Ex equipment. The traditional design approach assigns the appropriate types of protection for specific areas using statistical data, based on how is most likely or frequent an explosive atmosphere. EPL indicates the risk of ignition intrinsic to the equipment, independently from the type of protection adopted. It was recognized that it is advantageous to identify and mark all the products based on their intrinsic risk of ignition. This should make easier the equipment selection. This method is an alternative and not a substitute of the traditional one and so far has created some difficulty in understanding – from Cortem Group.

Supercritical Instrument Installations - The Tricky Process of Designing Impulse Lines for ASME B31.1 Compliance - Allan G. Gilson P.E. - When it comes to tubing, everyone knows that a grip-type tube fitting will meet or exceed the rating of the tubing itself. This makes instrument tubing installation easy—right? Simply ensure that the tubing is sized correctly, and everything will work. Piece of cake. The recent generation of coal plants in the United States (and around the world) has seen a major increase in the use of supercritical technologies due to inherent efficiency advantages over subcritical designs. However, no gain is without cost in some form. Greater efficiency requires considerably higher pressures and temperatures, resulting in significant new challenges for critical system instrument impulse line design and installation. In a supercritical plant, the pressures and temperatures for the main steam and feed water cycles routinely exceed that of conventionally fired drum-type boilers and combined cycle units. These elevated pressures and temperatures are particularly challenging for boiler manufacturers and engineers. Compliance with ASME B31.1 Power Piping requires much thicker piping and tubing walls, as well as stronger materials for valves and fittings - from FlowControl.

The Lowdown on Radar Level Measurement - Free-Air or Guided-Wave -- Which Do You Use When? - Walt Boyes - Radar level measurement is basically divided into two groups, free-air and guided-wave - from the excellent Control Global.

Application Considerations for Continuous Level and Inventory Monitoring of Powder and Bulk Solids - Continuous level measurement is about one thing, e.g. answering the question “how much stuff do I have”. There are many applications where you need to know how much material is in a bin, silo or other vessel type. Usually the desired engineering unit is expressed in terms of volume or weight. “Measuring” volume or weight is not always the most practical approach, sometimes it isn’t even viable. Take those silos you have, how do you weigh the ingredients if the silos weren’t installed with load systems? Not an easy or inexpensive question to answer. So what do we do? This is where continuous level measurement sensors and systems come into play and offer a viable and cost effective approach. The purpose of this white paper is to discuss and inform about the application considerations when you need to measure the level of material continuously or simply determine on a continuous basis how much stuff you have in your vessels - whilst this document is about many of the technologies available it does have a section on Laser level - from Blue Level Technologies.

Pressure Regulators

Thanks to our Sponsor Prochem Pipeline Products ICEweb's Pressure Regulator Page has been updated with more links.

Dealing with Droop - Maintaining the Set Point in Self-Contained Pressure Regulators - T. Gainer - When qualifying valves for a pressure-reduction application, chemical plant engineers must consider several factors. Initially, they must determine whether or not the application requires a control valve to be effective. Would a self-contained or piloted regulator be sufficient? To make this decision, plant personnel should consider (a) The pressure drop, or the difference between P1 and P2, (b) The set point, (c) The potential for large flow variations and (d) the level of importance of regulation/control. If it meets the design criteria, a regulator will prove a more effective means of pressure reduction in almost all cases. In addition to lower overall costs, a regulator offers other advantages," most important of which is fast response - from Chemical Processing.

Tank Blanketing Valves
Tank Blanketing Regulators for Effective Gas Blanketing - Over many years, gas blanketing has become a widely accepted practice in many industries. The process of gas blanketing is simply to create and maintain a slightly positive pressure in a storage tank, vessel or container with an inert gas - from SA Instrumentation and Control.

The Complete Blanketing and Safety Valve System - This technical bulletin gives a description of blanketing or padding, Blanketing Valve Operation and Performance Characteristics - from Anderson and Greenwood.

The Tank Blanketing Technique - Tank blanketing, also known to as tank padding, is the procedure of smearing a gas to the empty space in a storage tank or container (the term storage container refers to any container that is used to store products, regardless of its size). This technique is used for a variety of reasons and typically involves using a buffer gas to protect products inside the storage container. Some of the benefits of blanketing include a longer life of the product in the container, reduced hazards, and longer equipment life - from cheresources.com .

Tank Blanketing Basics Covered - Tank blanketing, or padding, refers to applying a cover of gas over the surface of a stores commodity; usually a liquid. Its purpose is either to protect or contain the stored product or prevent it from harming personnel, equipment, or the environment. In most cases the blanketing gas is nitrogen, although other gases may be used. Blanketing may prevent liquid from vaporizing into the atmosphere. It can maintain the atmosphere above a flammable or combustible liquid to reduce ignition potential. It can make up the volume caused by cooling of the tank contents, preventing vacuum and the ingress of atmospheric air. Blanketing can simply prevent oxidation or contamination of the product by reducing its exposure to atmospheric air. It can also reduce the moisture content. Gas such as nitrogen is supplied in a very pure and dry state - from cheresources.com

Surge and Lightning Protection

It will never happen to me? Don't you believe it...Globally, some 2000 on-going thunderstorms cause about 100 lightning strikes to earth each second!! This page provides a comprehensive range of links to help resolve the potential effects.

The following links are from ICEweb sponsor IDC Technologies.
Protection against Lightning Physical Damage and Life Hazard - SANS 10313:2010 & IEC 62305 Part 2 & 3 Explained - T.J. Manas - This paper covers the process of assessing the risk of damage caused by lightning and give an in depth description of the requirements of protecting structures and living beings against the hazards of lightning - from IDC.
Lightning Protection for Equipment on MV feeders - WJD van Schalkwyk and M. du Preez - This paper presents the influence of lighting on MV feeders supplying small power users (400/230V). Attention is given to insulation failures leading to poor power quality. In order to minimize power interruptions, lightning related trips are reduced mainly by minimizing MV equipment failure. Examples of arc quenching are also studied.
Lightning Protection of Rail and Related Industries - AM (Bert) Hanekom - The rail environment is challenging and merciless. The overhead traction structure literally forms a huge lightning antenna. This requires a systems thinking approach to protect elements that are rail bound, rail mounted or in close proximity to the track, against lightning surges. What makes things even more challenging is the rapid growth in the use of low powered electronic devices in the rail environment. For example, signalling installations have evolved from mechanical interlockings to being based on sophisticated electronic sub elements. Additionally, condition monitoring of the rail infrastructure has brought in numerous electronic systems. Hence the critical need for lightning protection in all aspects of the rail network. The author’s real experience in lighting protection of rail systems is shared with you.
The Need to Ensure Energy Co-ordination of Surge Arresters in terms of SANS 10142:2009 section L.1.3.3 - Paul van As - This is a topic which is regularly overlooked and probably the most common cause for failure of surge arresters. Many people believe that the more surge arresters you install the better the level of protection obtained. This is all very well if viewed purely from a voltage protection perspective but can lead to premature failure of surge arresters. Cascading of surge arresters based purely on voltage protection levels without fully understanding energy co-ordination is a recipe for disaster. Many suppliers of surge arresters tend to sell their products purely on surge handling ability (kA), reaction time and clamping voltage. Obviously the surge arrester that reacts the fastest is the first to operate and hence takes most of the energy. In many cases this can lead to low energy, fast reacting surge arresters being overstressed causing damage to equipment. In light of the above problem SANS 10142-1:2009 section L.1.3.3, which states “When more than one SPD is connected on the same conductor, coordination between them shall be ensured.” Many manufacturers and sellers of surge arresters have no idea as to how their surge arresters will react when cascaded with each other. This problem is further aggravated when different surge arresters from different manufactures are installed in an installation.


Test and Calibration

Technical Papers and Articles on how to test and calibrate along with typical equipment. Thanks to our sponsor Zedflo Australia ICEweb's Test and Calibration Instruments page has been extensively upgraded.

Calibration Intervals, A Manufacturer’s Perspective - David Deaver - The analysis tools that are currently available for Calibration Intervals focus on setting intervals to achieve a desired reliability target. This paper suggests there is another perspective that these tools do not currently address; consequence cost or accumulated liability. A case is made that sometimes the reliability target is a secondary consideration to managing this consequence cost. The paper also addresses how manufacturers establish calibration intervals. The paper presents, and defends, the practice of using no analysis whatsoever in establishing the manufacturer's recommended calibration interval - from Fluke.

Temperature

Covering a whole range of temperature measuring techniques along with General Theory, Conversions, Selection and Application this page must be your first choice when looking for quality technical information.

Selecting Temperature Measurement and Control Systems - Steve Byrom - How to get accurate data and perform reliable control from systems designed for the rigors of industrial applications - Measuring and controlling temperature is undoubtedly the most common measured parameter because it is critical to so many operations and tasks. Accurate temperature measurement and control is vital to the quality of manufactured goods, such as finished metal components, and to the efficient and safe operation of a process or system. In today’s market, there are myriad devices for monitoring and controlling temperature, ranging from simple temperature controllers to complex distributed control systems. Most temperature measurement and data acquisition products are well-suited for the job for which they are intended, but care must be taken when applying them in harsh industrial environments - from the ISA and InTech.

Buying a Temperature Controller? - Understand the Specification Before you Order - Arthur Holland - A review some of the features and specifications of the commonly used discrete panel-mounted controllers. A review of all makes and features is impossible here, so to supplement this column, my best advice is, extend your reading to catalogues, operation manuals, FAQs and web sites of the top manufacturers. Technology help lines are so overloaded that they become impenetrable and direct you to existing sources of help. Rightly so - but be prepared to quarry your way through some hard to read material. With product knowledge in your brain and an eye on your process you can make a sound and economical choice of controller.

Information and News on Safety Instrumented Systems , Burner Management Systems, Manufacturing & Safety Automation, and Health & Safety.

Thanks to our sponsor Invensys Triconex ICEweb's Safety Instrumented Systems page has been extensively upgraded with an alphabetical listing - so if you need more information on SIS just go to this page as a first "port of call"!

Understanding Safety Integrity Level (SIL) - Understanding Safety Integrity Level - This brochure targets safety applications and Emergency Shutdown Systems. It provides an excellent overview of the concept. - from our sponsor Austral Powerflo Solutions and Magnetrol.

Functional Safety and Engineering Judgement - Harvey T.Dearden - Discussion of the role of professional judgement in the context of the functional safety standards IEC 61508 and IEC 61511. It is the role of a professional engineer, having acquired the appropriate competencies, to exercise professional judgement with due regard to pertinent guidance. In terms of the functional safety standards, engineers should recognise that we approach compliance asymptotically along a curve of diminishing return; we may approach closer and closer to full compliance, but it requires ever increasing effort and investment. There is a point where the marginal increase in compliance does not warrant the additional effort, which may be more gainfully employed on other safety concerns. Professional judgement must be exercised to identify when this point has been reached - from IDC.

The Importance of a Clear Safety Requirements Specification as Part of the Overall Safety Lifecycle -Andy Crosland - The need for specifying requirements clearly is recognised best practice for most automation projects, so it makes sense to be extra-vigilant when dealing with safety systems. Many project specifications cover functional and user requirements in great detail, but often miss the key safety considerations set out in IEC 61511. As well as the obvious benefits of a clear specification from the outset, the Safety Requirement Specification (SRS) is the essential reference document for the mandatory IEC 61511 Safety Lifecycle task of SIS Safety Validation. You will be shown the key SRS considerations, particularly why this information is so important at Validation time - from IDC.

Protection Functions as Probabilistic Filters for Accidents - Andreas Belzner - “Protection Functions” are instrumented control system functions for machinery or process installations, which are implemented for preventing specific accidents. Frequently, such functions induce an emergency shutdown of the controlled machinery. The over-speed protection function of a turbine is a typical example. The prevented accidents may affect assets only (equipment damages, production losses). They may endanger the health and safety of people, the environment or other values. Since the protection target is not relevant in the current context, the generic term “protection function” is used in this paper rather than “safety instrumented function”. For such protection functions, two sets of requirements are typically specified; (1) Functional Requirements and (2) Safety Integrity Requirements . The first set of requirements defines the protective action: emergency shutdown or others, within a specific time and so on. The functional requirements include as well the conditions for triggering the action - process signals, threshold values, voting logic and so on. The second set of requirements describes the reliance, which can be put on the function: How certain can one be that the function will work as designed, when required? - from IDC.

Who’s Afraid of IEC 61508/61511? - Harvey Dearden - This paper highlights some key issues for owner/operators that may help maintain the right perspective on the requirements as they apply to the limited circumstances that are typical of most process operations. It has to be said that the 61508 standard is something of a monster. That is not to say that we should turn tail and run however. But how are we to respond? The key is to keep the thing in perspective. In detailing a completely comprehensive, rigorous approach for the lifecycle requirements for protection systems from the simplest through to the most complex, the standard does become somewhat impenetrable. Things do improve with 61511, but it still could not be described as an easy read. The intention here is to highlight some key issues for owner/operators that may help you keep the right perspective on the requirements as they apply to the limited circumstances that are more typical of most process operations - from IDC.

Smart Valve Positioners and their Use in Safety Instrumented Systems - Thomas Karte, Jörg Kiesbauer - As part of efforts to reduce life cycle costs of control valves in the process industry, smart electro-pneumatic positioners play an important role due to their self-adaptive features and their highly developed diagnostic functions. Their use can lead to decisive improvements in availability and reliability. To make full use of this potential, which has often been discussed in theory in the past but hardly been put into practice to date, NAMUR Recommendation 107 and Guideline VOl 2650 provide information on the scope of diagnostics and the generation of alarm states. Applications in safety instrumented systems are of particular interest as smart positioners are used more and more with on/off valves in place of classic solenoid valves. In the process industry, the use of on/off valves in safety instrumented systems is governed by the IEC 6 1511 standard. The basic principle behind this standard is the safety management life cycle, which can be effectively supported by the diagnostic functions of positioner - from Samson Controls.

Playing it Safe - How Information Management Technology is essential to meet more stringent Process Safety and Regulatory Compliance - Process Safety and Compliance are universal issues across all the world’s plant industries and individual regulatory authorities are increasingly collaborating to share ideas and to normalise globally consistent, best-practice requirements. These authorities have recognised the potential of Information Management technologies for supporting safe and compliant operations and we can expect to see their use progressively being encouraged, expected and mandated as regulations advance. But the issue is not only one of maintaining regulatory compliance. The US Centre for Chemical Safety claims that an average offshore incident costs an Owner Operator $80 million, so there is a serious economic incentive involved as well. This paper examines current capabilities, opportunities and likely future directions in the application of technology. For convenience, reference will be made to new offshore regulations emerging in the USA, as these are likely to set benchmarks for global regulatory standardisation - from ICEweb Sponsor AVEVA.

Understanding Safety Life Cycles - IEC/EN 61508 is the basis for the specification, design, and operation of safety instrumented systems (SIS) - The international standard IEC/EN 61508 has been widely accepted as the basis for the specification, design, and operation of safety instrumented systems (SIS). In general, IEC/EN 61508 uses a formulation based on risk assessment: An assessment of the risk is undertaken and, on the basis of this assessment, the necessary safety integrity level (SIL) is determined for components and systems with safety functions. SIL-evaluated components and systems are intended to reduce the risk associated with a device to a justifiable level or “tolerable risk.” When considering safety in the process industry, there are several relevant national, industry, and company safety standards used when determining and applying safety within a process plant - from ISA and InTech.

Safety Alert - Risks Associated with Pneumatic Hose Couplings - NOPSEMAOHS regulatory specialists have noticed that pressurised air hose couplings have been incorrectly assembled on some facilities. During one inspection, the inspector found that a coupling had been assembled without a safety pin to secure the fitting.

Flare Pilot Systems and Ignition Systems
- Developments in the Field of Electronic Ignition Flaring Systems - With the developments in chemistry and petrochemistry on one hand, and concern for the environment on the other, more and more requirements are being set for the emission of flaring systems. Flaring systems have undergone considerable development, from a pipe with a perpetual flame to a well thought-out combustion system with pilot flame burners, purge gas, steam injection and automatic ignition - from Smitsvonk Holland BV.
- Install Electronic Flare Ignition Devices - This technology replaces the intermittently or continuously burning flare pilots with electrical sparking pilots similar to a modern gas stove. These sparking pilots require low electrical power that can be supplied from a battery with solar recharge in remote sites. In addition to using electronic flare ignition devices for pilots, facilities may also install sensors to detect the pilot sensors to detect the pilot flame and shut off fuel gas if the pilot is extinguished - from EPA.
- Flare Pilot System Safety - John Bellovich, Jim Franklin, and Bob Schwartz - One of the worst nightmares a plant manager can experience is a complete flare system outage. The flare system is the last line of defence for many refining and petrochemical facilities and, when out of commission, can cause the shutdown of the entire facility. Flare ignition failure may lead to unburned venting of dangerous gases, and may develop into an explosive hazard leading to the loss of property and equipment, or worse, injury to personnel or loss of life. The safety and effectiveness of flaring are dependent upon one or more continuously burning pilots for immediate and sustained ignition of gases exiting a flare burner. Because pilot failure can compromise safety and effectiveness, it should be detected quickly and accurately to allow prompt automatic and/or operator response. Proper disposal of process and waste gases during routine and/or emergency conditions is crucial to help operating facilities protect plant employees and the surrounding community, and to avoid hundreds of thousands of dollars in fines. These reasons alone make the pilot monitoring and ignition system the most important component of any flare system. The advanced flare pilot systems explained in this article offer increased protection from harsh environmental conditions and rapid notice of pilot flame failure. Recently published industry standards for flare pilot design and performance are also discussed - from John Zinc Company.

News and technical links to Industrial Instrumentation Wireless items of interest

Discrete Wireless - Bill Lydon - Wireless discrete monitoring and controls standards emerging - Industrial wireless is proving valuable for automation professionals in many areas of industrial automation with products and standards emerging. People are comfortable with wireless since they use it in their daily lives with cell phones, personal computers, security monitoring, and other devices. Wireless standards to date have focused on analog sensors, but there is growing interest and adoption of wireless for discrete monitoring and for controlling digital output points. Discrete monitoring and control points significantly outnumber analog input and outputs in automation systems and are the largest installation cost on most projects. Discrete points monitor contact closures from a wide range of sensors and use contact outputs to control a wide range of devices, including motors, two position valves, and solenoids. If wireless cost and reliability improve to compete with hardwiring, this would be a real improvement in automation systems. Today, wireless sensors are being applied to select applications that have a high return on investment as a low-cost means for monitoring hard-to-reach locations and deploying new innovative applications. Examples include connecting far distant sensors that are too expensive to wire, such as tank monitoring/control, and as an alternate to electromechanical slip rings on rotating machines connecting electrical signals from a stationary to rotating structure - From the ISA and InTech.  

Expanding plant Networks with WirelessHART - With process instruments getting ‘smarter’ every year, their capabilities are often under utilised. Important data that could help save costs remains unused. This potential can be tapped by using WirelessHART. Intelligent devices, whether they are valve positioners, temperature devices, flow meters or level meters, supply additional data such as secondary process variables or device diagnostics that can be used to obtain a better insight into the process. This data can be made accessible using a HART data transfer protocol. Although new control systems are HART enabled, the many legacy control systems in the field frequently lack the ability to collect HART data. The WirelessHART standard can be used in both retrofit and greenfield installations, providing distinct advantages for each - from Process On-Line.

Yokogawa Electric Corporation have announced the introduction of a new "Wireless Anywhere" business concept on the plant-wide use of ISA100.11a compliant wireless communication technologies for both monitoring and control applications. The ISA100.11a standard ensures high reliability, application flexibility, network expandability, and compatibility with a variety of wired communication standards such as FOUNDATION™ fieldbus, HART®, and PROFIBUS. "ISA100.11a full functional" field wireless network systems and devices make use of state-of-the-art dual redundant technologies that enable a much higher level of reliability, and allow massive scalability and long-range communications.

Wireless Plant: Complete Coverage - Becoming an important part of a company’s infrastructure both outside and inside a plant environment. The wireless infrastructure can be used for both network and process data communication, however coexistence must be considered early in the design of plant-wide wireless systems. This article details a mesh network infrastructure complete with I/O, gateways and IS equipment capabilities – from MTL.  

ISA100 Gives Up on Convergence - No Deal Between ISA 100 and Wireless HART Standards. Back to the Drawing Board - Dick Caro - After spending almost four years to find a technical path to converge the WirelessHART specification (IEC 62591) with that of ISA 100 Wireless (ISA/ANSI 100.11a, IEC 62734), the ISA100.12 WirelessHART Convergence Subcommittee has abandoned its work without finding a single convergence solution - from Control Global.

Leveraging Dod Wireless Security Standards For Automation And Control - Over the last several years, the use of wireless networks in control systems has yielded a number of benefits to critical infrastructure while revolutionizing operations in key areas of industry, such as energy and transportation. Apart from the benefits of eliminating signal and power wiring, wireless sensor networks can enable measurement applications in sites that are hard to access, or where the wiring cost cannot be justified. They are also invaluable for modernizing existing legacy facilities, for temporary installations, or for locations where a power source is not available. However, the practical implementation of wireless technology in industrial settings has faced a number of challenges, not least of which is the adoption of industry security standards. The increased transmission of plant data through networks has given rise to ominous cyber attacks that threaten networks, businesses, and end-user devices alike. Wireless sensor networks (WSN) are currently receiving the most industry attention focused on such areas as condition monitoring, process control, wireless instrumentation, and measurements. One of the greatest inhibitors to the adoption of WSN in the private sector is the concern for security in critical industrial applications - from ISA and InTech.
