CEMS – Continuous Emission Monitoring System
Introduction to CEMS
Continuous Emission Monitoring System (CEMS)
In today’s increasingly regulated industrial environment, real-time transparency in emission control is not just a requirement — it is a responsibility. CEMS (Continuous Emission Monitoring System) is an advanced technological solution designed to measure and record gas emissions from industrial stacks and chimneys on a continuous basis.
What is CEMS?
CEMS is a complete system that continuously monitors key pollutants emitted from industrial processes. It provides accurate, real-time data on emission levels to ensure compliance with national and international environmental regulations.
Key Parameters Monitored:
- NOx (Nitrogen Oxides)
- SO2 (Sulfur Dioxide)
- CO (Carbon Monoxide)
- CO2 (Carbon Dioxide)
- O2 (Oxygen)
- Dust / Particulate Matter (PM)
- HCl, HF, NH3, and other specific gases (upon request)
- Flow rate, Temperature, and Pressure
Main Components of CEMS:
- Gas Sampling Probe & Conditioning System
- Gas Analyzers (NDIR, Chemiluminescence, UV Fluorescence, etc.)
- Opacity / Dust Monitor
- Data Acquisition and Processing System (DAS)
- Remote Monitoring & Reporting Platform
Benefits of CEMS:
- Ensures full compliance with environmental standards (QCVN, EPA, EU directives, etc.)
- Real-time emission data for immediate process optimization
- Reduces risk of environmental penalties and shutdowns
- Supports sustainable development and green manufacturing
- Provides historical data for reporting and analysis
Wili offers reliable, high-accuracy CEMS solutions tailored for power plants, cement factories, chemical plants, steel mills, and waste incinerators. Our systems are designed for long-term stability, low maintenance, and easy integration with existing plant control systems (SCADA/DCS).
