ABSTRACT:
A method is provided for converting the hydrogen sulfide in a hydrogen sulfide containing feed gas into elemental sulfur by oxidizing the hydrogen sulfide with an oxygen containing gas to produce elemental sulfur in a Claus plant, wherein the oxygen containing gas is axially introduced into an end portion of the reaction cylinder of the Claus plant and the hydrogen sulfide containing gas is introduced through at least one gas inlet in the side wall of the reaction cylinder at an oblique or perpendicular angle with respect to the direction of the flow of the oxygen containing gas so that the hydrogen sulfide containing gas introduced through the side wall surrounds and swirls about the oxygen containing gas, thereby allowing higher combustion temperatures to be achieved within the reaction cylinder which enhances the efficiency of the combustion and enhances the efficiency of decomposing any ammonia in the gas while keeping the very hot zones away from the refractory material lining the interior of the reaction cylinder.
