FREMGANGSMAATE VED FREMSTILLING AV SVOVEL
Improved process for the production of sulphur from a gas containing H2S, SO2, H2 and/or CO, in which the gas is caused to pass through a CLAUS catalyst in a primary catalytic stage operating at between 200 DEG and 460 DEG C. in order to form sulphur, and thereafter the sulphur contained in the reac...

| description | Improved process for the production of sulphur from a gas containing H2S, SO2, H2 and/or CO, in which the gas is caused to pass through a CLAUS catalyst in a primary catalytic stage operating at between 200 DEG and 460 DEG C. in order to form sulphur, and thereafter the sulphur contained in the reaction mixture issuing from this stage is condensed through indirect heat exchange with water to produce steam. The improved process consists in constituting at least the final eighth of the catalyst volume in this stage by a composite mass formed from a refractory oxide on which is fixed a transition metal compound, for example Co and/or Mo, and in entering into contact the gas with this composite mass at between 300 DEG and 460 DEG C. in order to oxidize H2 and CO. The energy resulting from this oxidation is recovered in the form of a supplementary quantity of steam during the sulphur condensation. |
