ABSTRACT:
A process and apparatus for elemental sulphur recovery from acid gases. By this process, acid gas, a by-product of sour natural gas from crude oil processing plants, is mixed with air and introduced to a partial oxidization furnace, and hot products of oxidization are then passed to a catalyst regenerator where elemental sulphur is vaporized. The sulphur is then recovered in a sulphur condenser, and regenerated catalyst is recycled to a catalyst contactor in a continuous flow arrangement. Also disclosed is a sulphur recovery apparatus comprising a catalyst contactor, catalyst regenerator, and sulphur condenser which operates in continuous fashion.
