Continuous Emissions Monitoring of HCL

Combustion gases generated at municipal, industrial and hospital waste incinerators contain high concentrations of hydrochloric acid (HCl) formed while burning plastics and chlorinated materials and solvents. Typically, these combustion gases pass through an acid gas scrubber prior to their being emitted into the atmosphere. A continuous HCl monitoring system, like the one shown above installed at a hospital waste incinerator, can assure the efficient use of the scrubbing medium (generally limestone as a dry powder or wet slurry) and provide a permanent record of acceptable HCl emissions.

The Servomex HCl continuous emissions monitoring system has MCERTS (European) approval. A highly sensitive gas filter correlation infrared analyzer with heated sample cell measures HCl with a minimum full scale range of 100 parts per million. Maintaining the entire sampling system from sample probe to measurement cell above 180 degrees Celsius assures minimal loss of HCl due to condensation and protects the sampling system and analyzer from corrosion.

In addition to HCl Servomex also provides continuous emission monitoring analyzers and systems for O2, CO2, NO/NOx, SO2, and CO.
