HCl Monitoring In Stacks And Scrubbers

Due to its polluting effects, hydrogen chloride (HCl) levels in industrial exhausts are of growing concern. To ensure levels are within required limits, HCl monitoring equipment is installed on stacks and scrubbers where the gas is present. However, measuring the gas can be very challenging with commonly used technologies. In situ, probe-type analyzers using tunable diode laser spectroscopy offer a cost-effective, low maintenance and reliable alternative.
