ABSTRACT:
streams. The method includes contacting the sulfide-containing gas stream with an aqueous scavenging mixture which includes a scavenging compound, that is a product of reaction between an aldehyde and a nitrogen compound, an inorganic ion and an oxidation catalyst: regenerating at least a portion of the scavenging compound with an oxygen-containing gas and returning at least a portion of the aqueous scavenging mixture to the contacting zone.
