Hydrogen Chloride

Hydrogen chloride (HCl) is formed as a byproduct when chlorine-containing items in the waste, such as chlorinated plastics (including polyvinyl chloride, PVC) are burned.

The air pollution control system is the same as for SO2. In the case of HCL, lime slurry (calcium hydroxide) chemically combines with hydrogen chloride to neutralize the acid gas and form calcium chloride particles, which are then removed by the fabric filter baghouse.

The permitted emission limit for HCl is 25 parts per million (ppmv), or at least (>=) 95% removal efficiency, for stack test data only. There is no permit requirement for the continuous emissions monitoring (CEM) data because the CEM sensor for HCl is not yet certified by the U.S. Environmental Protection Agency (EPA). Emissions monitoring data over the last five years indicates that over 95 percent of HCl is removed by the air pollution control system. The HCl levels, on the average, have been less than 20 ppmv, compared to the permitted emission level of 25 ppmv.
