Sulfur recovery process using metal oxide absorber feed for regeneration
This patent describes a process for the recovery of sulfur and sulfur compounds from a gaseous stream comprising hydrogen sulfide, the process comprising: (a) introducing the gaseous stream into an absorber zone comprising a metal oxide absorbent effective for removal of at least hydrogen sulfide from the gaseous stream; (b) removing at least hydrogen sulfide from the gaseous stream in the presence of the metal oxide absorbent and producing a laden absorbent and absorber effluent reduced at least in hydrogen sulfide content; and (c) regenerating the laden absorbent in a regeneration zone using a regeneration gas consisting of an oxygen-containing stream blended with gas-in-process withdrawn from upstream of all of the absorber units in the absorber zone, the resulting diluted oxygen-containing stream being passed in contact with the laden absorbent and regenerating the absorbent, thereby producing regeneration effluent comprising sulfur dioxide.
