Continuous Emission Monitoring Applications

 Continuous emission monitoring systems or CEMS are generally used to monitor flue gas for oxygen, carbon dioxide and carbon monoxide. It is a type of tool that delivers information in order to control combustion in industrial areas. The monitoring system is also used in compliance with air permission standards such as federal emission programs or state permitted emission standards like the United States Environmental Protection Agency’s Acid Rain Program. a lot of industrial and commercial industries continually utilize CEMS in order to record, collect and report emissions data required by the government.

Features and Applications

Some of the most notable features and applications of continuous emission monitoring systems include the following:

  • The device comes with an advanced analyzer or sampler that processes data on its own and is installed within the device. There are also analyzers that are placed near outside but nearby the source of emission.
  • The tool has a collecting data centre that forwards emission data to supervising agencies in real time. The tool also analyzes the data on its own thereby reducing labour costs and energy needs.
  • The device which analyzes gas is intolerant of contamination by condensed liquids. Thus, in order to get accurate results and for it to function properly, the device should be presented with clean gas. The presentation should also be in perfect timing. Using contaminated condensed liquid can obstruct flow components and blur optical lenses and sensors thereby giving out unreliable and questionable results.
  • The system also uses gas sample analysis wherein it measures the concentration of sample gas constituents. The device measures the physical characteristic of the subject by using techniques such as ultraviolet adsorption, infrared, photo or flame ionization, catalytic or chemiluminscence photon emission from chemical reaction. When there is cross-interference in the gas sample constituents, techniques are commonly used to cancel the interferences or at least reduce them. In order to get accurate results, it is important to choose the right technology for gas conditioning and analysis.
  • The continuous emission monitoring system also comes with data acquisition wherein it functions as the system controller and collector and recorder of data gathered. It also functions to monitor important system parameters, daily calibrations, reports, generates alarms and communicates with the client’s network. It also functions as a tool for accounting for maintenance purposes and for system upgrades in the future. The device should also have a means to validate the data collected.

How to Make CEMS Work

In order for continuous emission monitoring system to work perfectly, it should be integrated with other components during operation. The technology and application of components selected should be complementary to the application in order for the system to become reliable. The primary requirement for CEMS to work is to have a good design. The basic things that should be put into consideration when creating a design for CEMS is its source of characteristics, its applications and how the device is going to be used. With careful planning, the device will function for a long time with full reliability. 

I use continuous emission monitoring to monitor the concentrations of oxygen - in my workplace it's vital that they are kept at a certain level otherwise employees could be endangered and there could be safety concerns.
