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.
