Continuous Emissions Monitoring Systems

Definition

Continuous emissions monitoring systems (CEMS) are automated systems used to measure and record the emissions of pollutants from industrial sources in real time. These systems play a crucial role in environmental regulations and standards by ensuring compliance with air quality requirements, providing data for regulatory reporting, and helping industries minimize their environmental impact.

5 Must Know Facts For Your Next Test

1. CEMS are required by many regulatory agencies to ensure that industrial facilities continuously monitor their emissions to comply with local and national air quality standards.
2. These systems provide data on various pollutants, including particulate matter, sulfur dioxide, nitrogen oxides, and volatile organic compounds.
3. CEMS can be integrated into facility operations to enable real-time decision-making and quick responses to exceedances of emission limits.
4. The data collected by CEMS can be used for reporting purposes, helping industries demonstrate compliance with environmental regulations and avoid penalties.
5. Advancements in technology have led to more accurate and reliable CEMS, making them an essential tool for industries aiming to reduce their carbon footprint.
