CEMS — Continuous Emission Monitoring Systems

A continuous emission monitoring system is not an instrument but an installation: sampling probe, heated line, pretreatment, analyzers, particulate monitoring and a data system that reports to the regulator's platform. It exists where an emission permit demands continuous proof rather than periodic tests.

The company's published CEMS solution — set out in its thermal power plant case — combines a dedicated pretreatment unit, online monitoring of gases and particulate matter, long-distance sampling and integration with multi-region regulatory platforms. This category page frames that system offer; the component analyzers live in the analyzer categories.

System anatomy

Pretreatment decides a CEMS project's fate: stack gas is hot, wet and dirty, and analyzers are none of those things. Conditioning removes water and dust while preserving the measured gases. Long-distance sampling covers stacks whose analyzer shelter cannot sit at the measurement plane.

The data layer is as specified as the hardware: averaging periods, validity flags and regulator formats are part of the deliverable, which is why CEMS is quoted as a system against the permit, never as a catalogue line.

CEMS or campaign measurement

Where the permit allows periodic testing, portable analyzers (flue gas, NMHC, VOC) deliver the numbers at a fraction of the commitment. The emission monitoring guide walks through the decision; the flue gas category covers the campaign instruments.
