CEMS

Continuous Emissions Monitoring Systems (CEMS) are used to provide data for compliance with regulatory requirements for the control, monitoring and reporting of pollutant emissions. CEMS can include monitors for CO, CO2, H2S, NO, NO2, SO2, O2, THC, Hg, HCl or Opacity.

CEMS are either in-situ, the measurement is performed in the stack or duct, or extractive, where the gas is removed from the stack or duct and transported to the analyzers.

Extractive CEMS can be either straight extractive, utilizing a vacuum pump to draw the sample from the stack to the CEMS; or dilution extractive, where a precision eductor uses very clean air to extract a sample, at the same time dilute it, then deliver the sample to the analyzers.
