Off-Gas System BMT 965 OG

Ozone-in-Off-Gas Analysing System for measuring ozone in moist off-gas, please contact us for different configurations! The OZONE-IN-OFF-GAS ANALYZER BMT 965 OG is part of an ozone analysing system for moist ozone off-gas, typically consisting of the three major components: • UV-photometric ozone analyser (inside BMT 965 OG) • Peltier-electric sample gas dryer DH6 • ozone resistant sample gas pump (inside BMT 965 OG) Measuring the ozone content in an ozone process off-gas is not a simple task. Not one process actually equals the other. Usually the ozone off-gas comes from a reactor vessel at about atmospheric pressure, and has a high dew point temperature equal to, or even exceeding, the ambient temperature. An ozone resistant sample gas pump is needed to bring the sample gas to the ozone analyser. To prevent condensation in the sample tube, water vapor has to be removed from the sample to reduce dew point temperature below the deepest ambient temperature which could occur. Using a sample gas pump has an important advantage: The ozone sample gas can be directed back to the reactor after it has passed the ozone analyser. No ozone destruct is necessary.
