Continuous Emission Monitoring
Opsis systems for continuous emission monitoring (CEM) set the standard for reliable and cost efficient solutions to any industrial monitoring needs. The systems are based on Opsis’ gas analysers utilizing open-path DOAS technology for measurement of concentrations of a wide range of gaseous compounds. Measurements can often be made in-situ, thereby excluding any need for extraction and dilution of the flue gases. This is of particular interest where the flue gas is dust-laden, high humid and/or aggressive.
Cross-Stack UV & FTIR DOAS Systems
OPSIS CEM systems measure multiple emissions or process gases in real time in situ. Using the DOAS (Differential Optical Absorption Spectroscopy) technique, the system is non-contact, with fast response.
One system can be configured to monitor NO, NO2, SO2, O3, H2S, NH3, CO, CO2, HF, H2O, CH4, Hg, HCl, Cl2, ClO2, CS2, Phenol, Formaldehyde, among other gaseous compounds
A basic system includes an analyser, an emitter/receiver set, and an optical fibre cable.
