Emission monitoring

KEMA has great experience in determining and measuring NOx and other GHG emissions, as well as proper equipment to measure relevant components in flue, process and exhaust gases

The most direct way of measuring NOx emissions is to install appropriate instruments in your plant’s chimney. KEMA operates a number of mobile test stations equipped with sophisticated calibrated analysis equipment, which can be used to measure all relevant components in flue gases, process gases and exhaust gases. We also have a great deal of experience in the accurate determination of NOx and other GHG emissions. We work to standardized methods and our Emission Measurement department is both "RvA-Testing L256" accredited and ISO 9001-certified. All relevant components in flue gases, process gases and exhaust gases can be measured.

Using the data collected, we design a Predictive Emission Measurement System (PEMS) or define reference figures for the installation. Furthermore, emission measurements are easily combined with performance measurements: comparative measurements in accordance with NEN-EN 14181 are obligatory for class 1 installations. The measurement of CO2 emissions is not so straightforward. As a result, these emissions and any reduction in them are often determined mathematically.

Started as a supporting facility to our own emission measurements department, our Calibration Laboratory offers it's services also to interested parties in the market. The laboratory is "RvA-Calibration K103" accredited for the certification of binary gas mixtures and the calibration of gas analyzers and flow meters.
