Abstract

Process for recovering the sulfur content, such as elemental sulfur, from organic, liquid, sulfur-containing wastes, characterized in that it comprises burning the sulfur-containing residues in a combustión chamber with oxygen in excess of the amount required for the total oxidation of the material fuel, to thereby form a gaseous combustión product; feeding said gaseous combustión product a reducing gas; then successively directing the mixture of combustión product and reducing gas through at least one cooler, a condenser and a catalytic bed; and recover elemental sulfur from the condenser.
