ABSTRACT:
A process to remove ammonia from gases by washing the gases with an inorganic acid of ammonium bisulfite. The ammonia removed from the gas transforms the washing liquid into ammonium salt solution. This salt solution then undergoes a separate processing by washing it with gases bearing sulfur dioxide to regenerate ammonium bisulfite acid, a portion of which is returned for further washing of the gases and another portion is diverted to an apparatus for concentrating the acid solution up to 70% to 80% by weight after which the concentrated acid solution is delivered to a combustion chamber where burning thereof produces combustion products bearing sulfur dioxide which are used in the process to wash the ammonium bisulfite salt solution to regenerate ammonium bisulfite acid.
