Continuous Emission Monitoring Systems

Continuous emission monitoring systems (CEMS) measure airflow, dust, the concentration of air pollutants (such as SO2, NOx, CO, etc.), and other parameters related to emissions. Required parameters depend on the type of stationary source and local regulations. A standard CEMS consists of a sample probe, filter, sample line (umbilical), gas conditioning system, calibration gas system, and a series of gas analyzers that reflect the parameters being monitored. Typically monitored emissions include: sulfur dioxide, nitrogen oxides, carbon monoxide, carbon dioxide, hydrogen chloride, airborne particulate matter, mercury, volatile organic compounds, and oxygen. CEMS can also measure airflow, flue gas opacity, and moisture.

    Air Quality and the monitoring of pollutants that can cause health issues is becoming more important to our daily lives with governments and regulators keen to both monitor and manage the impacts of poor air quality caused by a range of pollutants.
    WIN-911: STMICROELECTRONICS INTEGRATES ALARM NOTIFICATION INTO ITS PRODUCTION CONTROL PRO
    Semiconductor production environments are “clean rooms” and must be tightly monitored in order to reduce the possibility of product contamination. A dusty environment will almost certainly lead to quality control issues. In order to prevent such disasters, STMicroelectronics installed a data monitoring and centralization system that instantly recognizes a problem and alerts the appropriate people.
