METHOD FOR REMOVING SULPHUR COMPOUNDS FROM A RESIDUAL GAS SUCH AS RESIDUAL GAS FROM A CLAUS PROCESS SULPHUR PLANT, AND RECOVERING SAID COMPOUNDS AS SULPHUR

摘要

the waste gas is subjected to a treatment involving a phasehydrogenation and hydrolysis (1) for the compounds.s under the sole form of h2s, a cooling (4, 10) ain the meantime.theta. temperature at 180 c,.theta. is thedewthe water in the gaseous effluent from the phase of hydrogenation and hydrolysis.catalytic oxidation, hydrolysis, and (2) of h2s to sulfurat temperatures in the range.theta. at 180 c, leading to asulphur deposition formed on the catalyst and periodic regeneration of thecatalyst for sulphur (2b), and cooling of the regenerated catalystin the meantime.theta. at 180 c for reuse in thephase catalytic oxidation.
