Japanese Patent JP3262123
Kind Code:
B2
Abstract:
Process for the improvement of the sulphur yield of an assembly which produces sulphur from from H2S and which consists of a sulphur plant (1), an oxidation and hydrolysis unit (2) and a purification unit (3). Said sulphur plant (1) in producing sulphur provides a residual gas (17b) which incorporates H2O, COS and/or CS2 and H2S and SO2 in a mol ratio of H2S:SO2 >/= 2:1. Said residual gas passes into the unit (2) on a H2S oxidation and COS and CS2 hydrolysis catalyst which functions between 180 DEG C and 700 DEG C, in the presence of air (47), thus producing a residual gas (38) free of COS and CS2 and incorporating H2S and SO2 in a mol ratio which is kept equal to 2:1 by regulating the air flow (47). The residual gas (38) is introduced into the purification unit (3), in which H2S and SO2 are made to react in order to produce sulphur and to obtain a purified residual gas (45).
