ABSTRACT:
This invention relates to a modified furnace for treating low-quality acid gas streams (those containing less than fifty percent (50%) hydrogen sulfide) to permit stable operation of combustion to provide a Claus furnace effluent. The system comprises burning a fuel gas and indirectly supplying the heat of this combustion to the hydrogen sulfide oxidant reaction wherein the hydrogen sulfide is converted to sulfur and other sulfur-containing products.
