Increasingly stringent air quality requirements have led to expanded use of wet scrubber systems to control pollutant gases released as air emissions. Chlorine storage facilities and chemical process plants are frequently required to scrub exhaust gas streams to remove halogen and acid gases. Unfortunately, monitoring reactive gas concentrations in moisture saturated air streams presents problems for standard diffusion gas sensors. Condensing water in these air lines can quickly blind standard diffusion transmitters, rendering them inoperable.
ATI’s Series B12 Wet Gas Detector was developed to meet the need for reliable measurements in wet scrubber outlets for other gas streams that might be saturated with water vapor. Gas detector systems have been developed for monitoring strong oxidants (chlorine, bromine, chlorine dioxide, or ozone), acid gases (HCl or HF), and hydrogen.
