The first use of the CEM system was to monitor the emission up of flue gases in an attempt to control industrial combustion. With time, industry began to focus more on environmental regulation and the continuous emissions monitoring system began to be used to monitor pollutants within gas emissions. Modern CEM equipment can be used for a variety of applications in regards to monitoring flue gases. These systems have gone from being large, expensive to maintain complexes of piping and alarms to low-cost, elegant systems due to industry and regulator demand.

The modern CEMs analyzer has developed in response to a need for a monitoring system that will help companies meet stringent Environmental Protection Agency (EPA) guidelines for operation. However, these sensors can detect very low levels of particulate matter within gases. Flue stack emissions can contain very low levels of pollution, down to as low as two hundred parts per million. The kind of CEM analyzer installed at a facility will depend on both the process occurring at the facility and also on the different pollutants that must be monitored. Companies ...
... will have to meet the requirements of the EPA as well as abiding by local environmental protection laws.

Typically, CEM equipment is intended to monitor one or more of these gas pollutants, Carbon Dioxide, Nitrogen Oxides, Sculpture Oxides, CO and Hydrocarbons. Almost any CEM system is used to detect these different particulates within emissions. Typically, the device is set up to draw gases through various filters that trap the particulates. The system then tests the contained material to determine the volume of each different particulate present in the gas emissions of a facility.

The Extractive CEM and In-Situ Folded Beams are just two of the many different kinds of CEM analyzers on the market. The processes mentioned in the third paragraph are similar to what is used by the Extractive CEM. However, the In-Situ Folded Beam necessitates the use of a metal to capture rising gases. Inside the tube, a transmitter sends UV light into the tube that would reflect off of a mirror and back towards a receiver. The effect that the gases have on the UV light can supply valuable information about what was within the gases.

You have a number of options to choose from for equipment monitoring including in-service oil analysis and acoustics monitoring. Realistically, this is only one part of equipment monitoring. It is also essential to keep an eye on the wastes produced by any industrial application with continuous emissions monitoring.
