Catalytic process for the production of sulphur from a gas containing H2S

摘要

Catalytic process for the production of sulphur from an acid gas containing H2S, in which a part of H2S is catalytically oxidized in order to form an effluent containing H2S and SO2 in a molar ratio of 2:1 and a given quantity of sulphur. The effluent is then contacted with a CLAUS catalyst to form a further quantity of sulphur. Said process involves: an oxidation reactor with a fixed bed an indirect gas/gas heat exchanger deoxygenation reactor having a fixed bed a catalyst conversion battery a thermal incinerator.
