DESCRIPTION
Increasingly stringent air quality standards have led to expanding use of wet scrubber systems to control atmospheric emissions. The main requirement of a monitoring system in this application is to detect breakthrough of gases due to scrubber failure. Unfortunately, monitoring reactive gas concentrations in moisture-saturated air streams presents a problem for conventional sensors; condensing water tends to block lines and blind sensors. The Wet Gas Monitor from California Analytical Instruments, Inc. has been developed to meet the need for reliable measurements in wet scrubber outlets where the sample may be saturated with water vapour. The system has been built to be suitable to mount inside the vent / measurement point and as such there are no sample lines to become blocked. The system is available for strong oxidants (Chlorine, Bromine, Chlorine Dioxide or Ozone), H₂S, acid gases (HCl or HF), and Hydrogen.
