ABSTRACT:
A process is provided for the removal of HCl and HF from a hot gas stream concurrently with the removal of sulfur compounds. The process involves the introduction of an HCl/HF sorbent such as nahcolite, sodium bicarbonate, sodium carbonate or Trona in powder form into the process stream at any one or all of four alternative locations in an amount sufficient to break down the HCl and HF into solid salts which are subsequently removed from the stream.
