Abstract
In an apparatus for continuously recovering sulfur from a gas stream containing 0.1 to 3.0 vol-% HS, further gaseous sulfur compounds and sulfur, the gas stream first is passed over a reduction stage consisting of hydrogenation catalyst and then over a selective oxidation stage consisting of oxidation catalyst. To reduce the amount of apparatus involved, it is provided to arrange the reduction stage and the selective oxidation stage in a reaction tank and to leave a space for introducing a gaseous cooling medium into the gas stream between the two stages.
