초록

A process is provided for the production of sulphur from at least one sour gas containing H2S and a gaseous or liquid fuel effluent, of the type comprising a thermal reaction step, wherein the thermal reaction step is conducted by performing the combustion of the gaseous or liquid fuel effluent in a first zone of the thermal reaction stage with a quantity of a gas containing free oxygen in excess in relation to the theoretical quantity needed for a complete combustion of the fuel effluent, the excess being smaller than the theoretical proportion of gas c...

A process for the production of sulphur from at least one sour gas containing H2S and a gaseous or liquid fuel effluent, which comprises: (i) a thermal reaction step carried out in a thermal reaction stage and consisting of carrying out a controlled oxidation of the H2S in the sour gas and a complete combustion of the fuel effluent to produce a gas stream containing H2S, SO2 and sulphur vapor; (ii) a step of indirect cooling of said gas stream to separate the sulphur therefrom by condensation, and next (iii) a catalytic reaction step carried out on the g...
