FIELD: oil and gas industry.
SUBSTANCE: invention relates to a method for producing of hydrogen gas streams enriched with hydrogen sulfide suitable for a catalyst sulfidizing derived from the oil refinery saturated amines. Method comprises producing a high pressure gas stream comprising hydrogen sulfide from a hydro treating zone, contact of the acid gas stream with an aqueous amine solution in the contact zone to produce an upper gas stream depleted of hydrogen sulfide and an amine solution enriched with hydrogen sulfide, in the form of an outgoing bottom stream, contact of the enriched with hydrogen sulfide amine solution with hydrogen in the regeneration zone and recovering from the regeneration zone of the hydrogen sulfide-enriched hydrogen gas upper stream suitable for the catalyst sulfidizing.
EFFECT: invention provides a flow of the enriched with hydrogen sulfide hydrogen gas, at a given high pressure together with a convenient way to control the hydrogen sulfide concentration and the total flow rate without the need to compress the sour gas.
