ABSTRACT:
A continuous process for removing hydrogen sulfide from a gas stream by contacting the gas stream with a solution of ammonium hydroxide to produce an effluent liquid stream comprising ammonium sulfide which is fed to a heating zone maintained at least at the boiling temperature of said solution and supplied with an oxygen containing gas sparge wherein ammonia and hydrogen sulfide are removed from said zone as vapor and sulfur is removed from said zone as an aqueous dispersion, the sulfur being separated in a filtration zone from the residual aqueous liquid which is recycled back to a contact zone together with said ammonia and said hydrogen sulfide vapor.
