Which system continuously samples and analyzes stack emissions?

The Continuous Emission Monitoring System (CEMS) is designed specifically to continuously sample and analyze stack emissions from industrial processes or power plants. This system employs various analytical methods to determine concentrations of pollutants as they are released into the atmosphere, providing real-time data that is crucial for compliance with environmental regulations and for operational efficiency.

CEMS operates by using sensors and analyzers that gather data about emissions, including parameters such as carbon dioxide, nitrogen oxides, sulfur dioxide, and particulate matter. The continuous nature of this monitoring allows operators to detect and respond to issues promptly, ensuring that emissions levels remain within permitted limits.

This proactive approach to emissions monitoring helps not just in complying with legal requirements but also in enhancing environmental protection, thus minimizing the ecological impact of industrial activities. Other systems mentioned, like emission control systems or stack monitoring systems, may not provide continuous operational data or may focus more on control rather than real-time analysis.
