Brief description of the elimination of the compounds sulfurs contained in a residual gas, in particular from a claus sulphur plant has, with recovery of the compounds in the form of sulphur

摘要

Process for disposal of the compounds sulfurs contained in a residual gas, with recovery of the compounds in the form of sulphur, in which the residual gas is subjected to a treatment comprising a phase for the hydrogenation and hydrolysis 1 in order to bring the compounds sulfurs in the form of hs, a cooling 2, with condensation of water, a catalytic oxidation 3 of the claus hs stoichiometry and then a stage 4a of the claus reaction catalyst with deposition of the claus sulphur on the catalyst and regeneration of the catalyst, periodic charge of sulfur, 4b and then cooling of the catalyst regenerated. / p & & p & the gas used for regeneration and then cooling is levied 39 on the gaseous effluent 16 bring a catalytic oxidation 3 and the gas coming from the regeneration is hanging connection directly over spines a.sub.1 at least in part 40 in the gaseous effluent, after separation 28 of the sulfur which it contains. / p & & p & application for the purification of the gas coming from unit box wastewater a claus sulphur.
