Gitchel, W B

A sulfur bearing fuel is wet oxidized in the presence of an alkaline earth metal carbonate, of which the corresponding sulfate is insoluble. Ash and sulfate salt blown down from the wet oxidation are reacted at high temperature with another portion of the same or a different fuel to reduce the sulfate to sulfide. Carbonation of an aqueous dispersion of the sulfide releases hydrogen sulfide which is converted to elemental sulfur. Carbonate precipitates and is recycled.
