In recent years Online Emission Monitoring Technology has received attention and interest in context of providing
accurate and continuous information on particulate matter/ gaseous emission from stacks. There are already commercially available systems for monitoring parameters such as PM, HCL, SPM, SO2, CO, O2, CO2, NOx, SOX, etc. The Continuous Emission Monitoring (CEMS) System comprises of the total equipment necessary to determine the concentration of gaseous emission and/or particulate matter concentration and/or emission rate using analytical measurement.
