<p>This invention provides a process for recovering elemental sulfur from a gas containing hydrogen sulfide. The process comprises combusting the gas containing hydrogen sulfide in a furnace with an oxygen-containing gas to provide hydrogen sulfide and sulfur dioxide, the hydrogen sulfide and sulfur dioxide are then reacted to form a gaseous stream comprising water vapor, sulfur vapor, and other acid gas components. The gaseous stream is cooled and divided into a combined liquid water and liquid sulfur stream and a remaining process gas stream substantially free of water at a pressure greater than 50 psia such that water and sulfur are condensed concurrently and at a temperature above the sulfur melting point of approximately 248.degree.F. Subsequently the combined liquid water and liquid sulfur stream are separated into a product liquid water stream and a product liquid sulfur stream. The process of the present invention can be operated at high pressure.</p> |
