What is CEMS Analytical Technology?
CEMS analytical techniques are based on the physical and chemical properties and measurements of the interest parameters. The selection can be limited by both the source or the stack conditions, unless dictated by the approval requirements. There are CEMS analytical techniques used such as absorption spectroscopy, chemiluminescence, mass spectroscopy, UV fluorescence, paramagnetism, etc.
Stack gas flow, however, is used with pressure differentials, thermals or ultrasonic techniques. Industries such as pharma, refineries, pesticides, textiles and more are all using large quantum of pollutants through the effluent discharge and air emissions. These are very carefully monitored at all times.
A continuous monitoring system consists of sampling and analytical components and conditioning along with software designed to provide a direct line of continuous measurement. CEMS offer accurate information on the gaseous emissions and particulate matter from stacks. Whether the stacks are constantly monitored continuously depends on the specific industry at hand. CEQMS – or continuous effluent quality monitoring – is used in conjunction with CEMS for real-time air and water pollution monitoring.
The continuous measurement of pollution is analyzed and CEMS analytical technology goes through representative examples of air and water to ensure consistent monitoring. It’s an important tool for compliance enforcement and through credible pollution monitoring, and effective reporting practices, these are systems that can gauge real time data that’s accurate every single time. The data is gathered at a higher frequency with minimal manual intervention in order to strengthen the pollution control regime.
