Temperature moderation with water of an oxygen enriched Claus sulfur plant
This patent describes an improvement in a process for recovering sulfur from a feed gas stream containing 60-100 mole% hydrogen sulfide wherein the gas stream is partially combusted with oxygen-enriched air in a claus reaction furnace zone, a combustion effluent is cooled with the attendant condensation separation of sulfur in a condensation zone and the remaining effluent stream is further treated. The improvement comprising oxygen enriching the combustion in the range of 32-100 mole% oxygen and introducing a moderating stream of added liquid water into the reaction furnace zone in order to moderate the temperature of the reaction furnace zone in the range of 2400{degrees} to 2800{degrees}F.
