<p>Catalytic process for producing sulphur from H2S-containing acid gas wherein the acid gas is subjected to a catalytic oxidation (1) in CLAUS stoechiometry and to a catalytic CLAUS reaction phase (2a) with deposition of sulphur on the catalyst with periodic regeneration (2b) of the sulphur-laden catalyst and cooling of the regenerated catalyst. The gas used for the regeneration and for the cooling is tapped (33) from the acid gas (7) supplied to the catalytic oxidation (1) and the gas issued from the regeneration is reintroduced (27) into said acid gas after separation (26) of the sulphur contained therein. Application for treating acid gases having a low H2S content.</p> |
