Abstract
Process and system for recovering sulphur from a feed gas stream rich in hydrogen sulphide wherein the gas stream is partially combusted with an oxygen-enriched gas in a Claus reaction furnace zone, the combustion effluent is cooled with the attendant condensation and sepn. of sulphur in a first condensation zone and the remaining effluent stream is passed through at least one stage of reheating, conversion in a catalytic Claus reaction zone and cooling with attendant condensation and sepn. of sulphur in an additional condensation zone, the improvement comprising recycling a portion of the reacted effluent stream from the first condensation zone to the reaction furnace zone in order to moderate the temp. of the reaction furnace zone.
