Continuous Emission Monitoring System

KEMA houses expertise on all disciplines in relation to Continuous Emission Monitoring System: from consultancy to verification of the emitted particles

A Continuous Emission Monitoring System (CEMS) is the total equipment necessary for the determination of a gas or particulate matter concentration or emission rate using pollutant analyzer measurements and a conversion equation to produce results in units of the applicable emission limitation or standard.

CEMS are required under some of the US EPA regulations for either continual compliance determination or determination of exceedances of the standards. In the EU, combustion installations larger than 100 MWth are obliged to have a CEMS for monitoring their NOx emissions. The guidelines for continuous monitoring of NOx have been laid down in the Large Combustion Plant Directive (LCP) and other complementary national legislation.

Facilities which have a CEMS are further subject to:
- implement the “Quality Assurance of Automated Measurement Systems” (EN-14181 standard)
- to let execute an Annual Surveillance Test (AST)
- every three year the execution of parallel calibration and verification (QAL2) tests.

Hiring KEMA as independent service provider will take a burden of your shoulder. KEMA has all disciplines in house from consultancy on CEMS up to the verification of the emitted particles.
