Continuous Emission Monitoring Analysis

Continuous Emission Monitoring - C B Daw - The requirements for continuous emission monitors has changed significantly over the last ten years. This has been brought about by the increase in use of flue gas treatment systems, reducing the levels of pollutant to be monitored, and Environmental Agencies worldwide requiring smaller processes to be monitored. The Environmental Agencies have insisted that continuous emission monitors meet more stringent specifications, including repeatability and the capability to be fully challenged to demonstrate compliance. In addition, reporting regimes necessitate maximum availability. Pressure from the market place also requires the modern CEM system to have a low cost of ownership, which, in effect, means that high reliability must be a design criteria. There are many applications for continuous emission monitors, covering a variety of industries.The specification of the CEM system will depend on, not only the type of process, but also the pollutant gases that are required to be measured. The choice of the CEM system will depend on many factors, including the monitoring and reporting requirements of the local Environmental Authority - from Group Instrumentation

Advances in CEMS & Flow Monitoring- J. Ron Jernigan, P.E., DEE - RMB Consulting & Research, Inc., and Charles E. Dene Electric Power Research Institute. Since the promulgation of the Acid Rain Regulations required by the Clean Air Act Amendments of 1990, the electric utility industry has installed and certified over 1,500 new CEM systems. This paper identifies and discusses;
- The most widely used monitoring technologies and sampling acquisition techniques.
-   Monitoring technology changes that have occurred during the past five years.
-  Emerging CEM and flow monitoring technologies that may benefit the utility CEM user by enhanced measurement accuracy, reliability and lower maintenance cost.

RMB Consulting and Research have a very useful download library pertaining to Environmental Issues.

H2S Analyser - This Manual from Applied Analytics gives a good technical description of operation in Chapter 4.

Black Carbon the Elephant in the Room! - Jim Mills - Traditionally, ambient particulates have been measured gravimetrically according to their size. This article Jim Mills, demonstrates that the time has come to change or at least augment the way ambient particulates are monitored and regulated. It explains why the measurement of Black Carbon could change the way we look at particulate pollution, so that focus will be given to strategies that could result in improvements to human health AND make a very significant contribution to the fight against climate change. Also outlined is the rationale behind a new 3million EU funded project (Carbotraf ) which will use Black Carbon measurements to inform traffic management systems in both Glasgow and Graz.
