Continuous Emission Monitoring Systems ( CEMS)
1. Continuous Emission Monitoring Systems involve the installation of monitoring equipment in a stack or a duct in refineries with combustion systems such as incinerators, boilers, heaters, etc.
2. CEMS are used for the measurement of a number of pollutants. In other words; a tool to monitor gas for Nitrogen Oxides (NOx), Carbon Monoxide (CO) and Sulphur Dioxides (SO2).
3. They help to reduce combustion through uncontrolled oxygen emission in flue gases by monitoring on continuous basis, hence reduce energy consumption.
4. Further than providing assurance of good combustion, CEMS also provide a direct measure of emissions which consequently makes it easier for operators of units to interpret and make sure they are within the legal limits.
