CEMS – Continuous Emission Monitoring System
CEMS stands for Continuous Emission Monitoring System, a fully integrated solution designed to continuously measure, record, and report pollutant emissions from furnaces, boilers, and industrial stacks into the atmosphere.
What Does CEMS Measure?
The system typically includes analyzers, sample handling systems, and controllers configured to U.S. EPA standards, used to measure:
CO (Carbon Monoxide)
NOx (Nitrogen Oxides)
O₂ (Oxygen)
Additional gases as required:
SO₂, CO₂, HCl, HF, Mercury, THC
CEMS not only ensures compliance with environmental laws, but also helps evaluate combustion efficiency and monitor air quality in real-time.
Why Is CEMS Important?
Air pollution has become one of the most critical environmental concerns, affecting:
Human and animal health
Ecosystems including cities, forests, and water bodies
Climate and air quality standards
Governments now require industrial plants to install and report emissions through CEMS continuously.
Regulatory Requirements (Thailand – 2023)
New plants must complete CEMS installation before operation begins
Existing plants must install CEMS within 365 days from the June 2023 regulation date, or submit an action plan for compliance by 2027
