What is involved in CEMS integration?
A full CEMS integration is the specification, arrangement, and connection of all the components of a functional monitoring system. The components include everything from the point of extraction, sample transporting, conditioning, validations, to the final point of analysis, with all specified materials, tubing components, and instruments in between. These components are individually specified with the assurance of one fully functioning coherent and reliable system.
A fully integrated system includes accommodations for all required utilities (instrument air, nitrogen, power…etc), PLC for required control and monitoring, and communication with DCS for displaying the essential data as required, and DAS for collecting, storing, and processing the CEMS data including the required calculation for reporting the emissions data. The integration also includes the DCS and DAS programming, and a chart recorder as a backup.
Note that the analyzers are placed in a climate-controlled shelter to minimize the ambient temperature effect on the analyzer performance. An integrator usually provides the full engineering and integrating service for a fully integrated CEMS shelter, ready to install at the site. They can also provide the engineering service for all communication links and programming as required.
