Abstract:
1. A process for producing a hydrogen sulfide-enriched hydrogen gas stream suitable for catalyst sulfidation, comprising: (a) obtaining at least a portion of a high pressure sour gas stream comprising hydrogen sulfide from a hydroprocessing zone; (b) contacting the sour gas stream with an aqueous amine solution in a contacting zone to provide a hydrogen sulfide-depleted overhead gas stream and a hydrogen sulfide-enriched amine solution as an effluent bottoms stream; (c) contacting at least a portion of the hydrogen sulfide-enriched amine solution with hydrogen in a regeneration zone; and (d) recovering overhead from the regeneration zone, a hydrogen sulfide-enriched hydrogen gas stream suitable for catalyst sulfidation.
