ABSTRACT:
A method for removing hydrogen sulfide from gases, particularly coke oven gas, and for obtaining elemental sulfur in a Claus plant, characterized in that sulfur dioxide and elemental sulfur in the residual gases from the Claus plant are hydrogenated to form hydrogen sulfide which is mixed with incoming coke oven gas or the like prior to passing into a hydrogen-sulfide scrubbing unit. In this manner, essentially no sulfur compounds escape into the atmosphere.
