Abstract
A system and method of use thereof are disclosed for recovering sulfur from a feed gas stream containing hydrogen sulfide which is combusted with an oxygen-enriched gas in a Claus reaction furnace. Within the method, combustion effluent from a waste heat boiler associated with the Claus reaction furnace is divided into a first and second stream so that the sulfur in the first stream is condensed and then the stream is passed on to later Claus reaction stages, and the sulfur in the second stream is condensed and then this stream is introduced into the Claus reaction furnace to moderate the temperatures therein.
