High pressure process for sulfur recovery from a hydrogen sulfide containing gas stream
A process is described for recovering elemental sulfur from a gas containing hydrogen sulfide comprising combusting the gas containing hydrogen sulfide in a furnace with a oxygen-containing gas to provide hydrogen sulfide and sulfur dioxide followed by the reaction of the hydrogen sulfide and sulfur dioxide forming a gaseous stream comprising water vapor, sulfur vapor, and other acid gas components, cooling and dividing the formed gaseous stream into a combined liquid water and liquid sulfur stream. A remaining process gas stream is substantially free of water at a pressure greater than 50 psia so that water and sulfur are condensed concurrently and at a temperature above the sulfur melting point of approximately 248/sup 0/F. The combined liquid water and liquid sulfur stream are separated into a product liquid water stream and a product liquid sulfur stream.
