FIELD: petroleum chemistry; methods of compression and delivery of various hydrocarbon-containing gases under pressure. SUBSTANCE: proposed method consists in delivery of gaseous hydrocarbon-containing medium to liquid- and-gas jet apparatus, delivery of liquid hydrocarbon-containing medium under pressure to nozzle of liquid-and-gas jet apparatus by means of pump, forming gas-and-liquid mixture in jet apparatus during mixing gaseous and liquid hydrocarbon-containing media at simultaneous compression and absorption of gaseous medium by liquid hydrocarbon- containing medium, delivery of gas-and-liquid mixture from liquid-and-gas jet apparatus to separator, separation of gas-and-liquid mixture in separator into compressed gas and liquid hydrocarbon-containing medium and discharge of compressed gas from separator to consumer and liquid hydrogen-containing medium to pump inlet, thus forming circulation loop of liquid hydrocarbon-containing medium from which liquid hydrocarbon-containing medium is discharged and fresh liquid working medium is simultaneously fed to this loop. Delivered to circulation loop as fresh liquid working medium is diesel fraction of rectifying column. Part of liquid medium is discharged from circulation loop to hydraulic purification unit where sulfur compounds, unsaturated com[pounds and gases absorbed in liquid hydrocarbon-containing medium are removed from it. Pressure of gaseous hydrocarbon-containing medium is maintained at inlet of liquid-and-gas jet apparatus between 0.09 and 0.3 MPa, pressure of liquid hydrocarbon medium, between 2.0 and 10.0 MPa and pressure in separator, between 0.35 and 0.8 MPa. According to another version of invention, gas oil fraction of rectifying column is used as fresh liquid working medium. EFFECT: enhanced economical efficiency and ecological safety of proposed method due to reduced power requirements required for compression of gaseous medium and practically complete exclusion of losses of hydrocarbon products. 4 cl, 1 dwg
