CEMS ( Continuous Emission Monitoring Systems )

Continuous Emission Monitoring System (CEMS) is a system used to continuously and automatically monitor pollutant concentrations and other emission parameters from stationary sources, such as factories, power plants and incinerators.

This system consists of several main components, namely:

• Sample extractor: Takes a sample of emission gases from the smoke stream.

• Sample conditioning system: Dilutes, cools, and prepares gas samples for analysis.

• Analyzer: Measures pollutant concentrations and other emission parameters in gas samples.

• Data processing system: Collects and processes data from the analyzer and calculates emission levels.

• Reporting system: Sends emissions data to environmental authorities and stores data for compliance and process optimization purposes.

CEMS is essential for:

• Ensure compliance with environmental regulations: Emissions data from CEMS is used to ensure that industrial facilities comply with emissions limits set by law.

• Reduce environmental impact: By monitoring emissions in real-time, facility operators can identify and correct problems that cause increased emissions, thereby contributing to better air quality.

• Improve process efficiency: Emissions data can be used to optimize operational processes and reduce fuel consumption, which can ultimately lower operational costs.

Some common pollutants monitored by CEMS are:

• Nitrogen oxide (NOx)

• Sulfur dioxide (SO2)

• Carbon monoxide (CO)

• Carbon dioxide (CO2)

• Particles of Matter (PM)

New technological advances such as remote sensors and real-time data analysis continue to improve CEMS's ability to monitor emissions accurately and efficiently.
