FIELD: process engineering.
SUBSTANCE: proposed process comprises compression of boost hydrogen in first compressor to get first flow of compressed boost hydrogen. First flow of compressed boost hydrogen is compressed in second compressor to get second flow of compressed boost hydrogen. Said second flow of compressed boost hydrogen is separated as second flow of compressed boost hydrogen for hydraulic treatment. First flow of hydrocarbons is processed over first flow for hydraulic processing including second flow of compressed boost hydrogen and first hydraulic processing catalyst to get first effluent flow of hydroprocessing products. Second flow of hydrocarbons is processed over second flow for hydraulic processing including first flow of compressed boost hydrogen and first hydraulic processing catalyst to get second effluent flow of hydroprocessing products. Said second effluent flow of hydroprocessing products is separated to get vaporous second effluent flow of hydroprocessing products. Said vaporous second flow is added to said boost hydrogen flow upstream of said first compressor.
EFFECT: perfected feed of hydrogen to separate process units.
