Continuous Emission Monitoring System – Tata Steel Limited

TCE has designed an ambient air pollution monitoring station for Tata Steel Limited for monitoring (SO2, NOx, SPM, CO) and meteorology on a continuous basis.

For integration of the data with the plant systems, the readings are transmitted over wireless communication links to the Emission Monitoring Centre. The server in the system contains special purpose software to display and record the pollution data, on 24X7 basis, and generate reports required for its analysis, for submission to Pollution Control Board. An electronic board was designed for displaying information, related to ambient air quality, at the main gate.

Another unique feature was the design of a mobile van equipped with analyzers for measuring quality of ambient air, to measure pollutants within the plants and also around the Jamshedpur city.

Special features of this project included use of dilution technique, leading to reduced maintenance, designs for reliable performance, energy conservation and automated operation with minimal human intervention.
