Abstract

A procedure to reduce the total sulfur content of waste or exhaust gases of a Claus process, in which said waste gases are passed, at a temperature higher than 175ºC, and together with a gas containing hydrogen and/or carbon monoxide. carbon, on a Group VI and/or Group VIII sulfided metal catalyst, on an inorganic oxide support, after which the waste gases thus treated are passed through a liquid, regenerable, hydrogen sulfide absorbent, and the unabsorbed part of said waste gases, optionally after its incineration, is discharged to the atmosphere, the absorbent enriched in hydrogen sulfide being regenerated, and used again for new absorption of hydrogen sulfide, and taking a process Claus the gaseous mixture rich in hydrogen sulfide that is given off in the regeneration.
