Continuous Gas Analyzers for Emission Compliance
CGAs provide ppb to % concentration data of gaseous samples for the refining, petrochemical, natural gas, and specialty gas industries, plus many more. H2, CO, CO2, O2, NOx, SO2, and even more difficult components like HCl, THC, NH3, HF or CH2O can be monitored using various detection methods. A principal use for CGAs is Continuous Emission Monitoring (CEM) to meet environmental regulations. Rawson/Industrial controls offers multiple solutions, from NIR and UV, to in-line zirconium oxide O2 analyzers, to laser or mass spectroscopy, so we can tailor the measurement technique to our customers’ needs.
ABB Measurement
With over fifty years in analytical instrumentation, ABB provides continuous gas analyzers built for demanding process environments. Their offerings include the AO2000 CGA system, a modular analyzer platform for emissions and process gases, the Endura AZ O₂/Combustible series for continuous monitoring of oxygen and unburned fuel in flue gases, and ICOS Laser analyzers using off-axis cavity spectroscopy for ultratrace gas detection with high selectivity and stability.
