    摘要： A process and apparatus for the treatment of a gas that contains hydrogen sulfide and sulfurous anhydride, in which: a) the gas (3) contacts with an organic solvent (1) containing a catalyst in a gas-liquid reactor-contactor (2) so as to recover separately liquid sulfur and; a gas effluent containing sulfur vapor; subjecting the gas effluent to a first condensation zone (7) operating at 70-100° C. to deposit the sulfur in solid form on sufficiently cold walls of the equipment in zone (7), recovering resultant purified gas containing less than 30 ppm by volume of sulfur melting the deposited solid sulfur to regenerate the equipment, and recycling resultant liquefied sulfur to the reactor contactor.

    摘要： The invention has as its object a process for the treatment of a gas that contains hydrogen sulfide and sulfurous anhydride, in which: a) The gas (3) is brought into contact with an organic solvent (1) that contains a catalyst in at least one gas-liquid reactor-contactor (2); a gas effluent that contains vapor sulfur and liquid sulfur is recovered separately, b) Said gas effluent is introduced into a first condensation zone (7) that operates at a temperature of between 70 and 100° C. so that the sulfur that is contained in said gas effluent is deposited in solid form on the so-called cold walls of the equipment of the zone (7), c) When the clogging limit of said equipment of zone (7) is reached, said equipment is regenerated so as to melt the solid sulfur that is deposited inside said equipment for obtaining a liquid effluent, d) Said liquid effluent is recycled in the reactor-contactor, e) A purified gas that contains less than 30 ppm by volume of sulfur is extracted from the zone (7). An installation that allows the implementation of the process is also described.
