FIELD: oil and gas industry.
SUBSTANCE: invention is referred to extraction of flows of hydrotreated hydrocarbons. Invention is referred to hydrotreatment method with extraction hydrotreated hydrocarbons that includes hydrotreating of hydrocarbon material in hydrotreating reactor with production of hydrotreating effluent; stripping in regard to cold flow of hydrotreating effluent, which is a part of the above hydrotreating effluent flow, in cold stripping column by means of stripping medium with production of cold stripped flow; stripping in regard to hot flow of hydrotreating effluent, which is a part of the above hydrotreating effluent flow, in hot stripping column by means of stripping medium with production of hot stripped flow and fractionating of cold and hot stripped flows in the column of final fractioning to receive product flows. Invention is also referred to plant for hydrotreatment with extraction hydrotreated hydrocarbons.
EFFECT: significant saving on operational and capital costs.
