Abstract
A method for producing sulfur and energy from an acid gas stream containing hydrogen sulfide by partially combusting the acid gas stream to produce a combustion product gas, mixing a sulfur dioxide stream with the combustion product gas, separating sulfur from the mixture, combusting sulfur to produce sulfur dioxide and heat energy and passing at least a portion of the sulfur dioxide to the combustion product gas.
