Abstract: A process for removing hydrogen sulfide from a gaseous stream containing hydrogen sulfide by contacting said stream with an aqueous solution of ammonium hydroxide to produce ammonium sulfide; converting said ammonium sulfide to an ammonium polysulfide intermediate in an electrolytic cell at ambient temperature and pressure; and oxidizing said ammonium polysulfide to sulfur in a heating zone utilizing an oxygen containing gas sparge.
