Envitech's HCl scrubbers are custom-designed packed bed scrubbers to provide removal efficiencies in the range of 95% to 99.9% with a low pressure drop. The Envitech HCl scrubber first cools a hot gas stream to saturation using either a horizontal or vertical quencher depending on the size of the inlet gas flow.
The quencher can be constructed with AL6XN for temperatures below 1,000oF, or Hastelloy C276 for higher temperatures. The HCl scrubber uses random dumped packing, a mist eliminator, and a liquid distribution system to remove acid and toxic gases through absorption and neutralization. It is ideally suited for hot combustion exhaust streams including thermal oxidizers, kilns, industrial boilers, or incinerators.
