Continuous Emission Monitoring Systems

Definition

Continuous Emission Monitoring Systems (CEMS) are advanced technologies used to continuously track and measure the emissions of pollutants from various sources, primarily industrial facilities. These systems provide real-time data on emissions, helping ensure compliance with environmental regulations and contribute to air quality management and control strategies. By offering constant monitoring, CEMS play a critical role in identifying emission trends and enabling timely interventions to reduce pollution levels.

5 Must Know Facts For Your Next Test

1. CEMS are often required by law for certain industries, such as power plants and manufacturing facilities, to ensure they meet regulatory emissions limits.
2. These systems utilize various technologies, including infrared spectroscopy and gas chromatography, to analyze the composition of emissions.
3. Data collected by CEMS is crucial for regulatory reporting and can be used to assess the effectiveness of pollution control measures.
4. CEMS can provide alerts in real time if emissions exceed allowable limits, allowing for immediate corrective actions.
5. The integration of CEMS into environmental management practices supports efforts towards reducing greenhouse gas emissions and improving overall air quality.
