FIELD: fluidics. SUBSTANCE: pump inlet is connected to separator outlet wherefrom liquid medium escapes, thus forming separator-pump-liquid-and-gas apparatus-separator loop; plant is additionally provided with system for separation of absorbed gaseous hydrocarbon-containing medium from liquid medium which includes rectifying column with liquid medium supply units and liquid hydrocarbon-containing liquid medium and gaseous hydrocarbon- containing discharge unit; liquid medium supply unit is connected to loop in section of motion of liquid medium from separator to liquid- and-gas jet apparatus and hydrocarbon-containing medium discharge unit is connected to loop below point of connection of unit supplying liquid medium to rectifying column in way of motion of liquid in column. Used as liquid medium-sorbent is hydrogen-containing liquid which is akin to one of oil refining fractions by its properties. Part of liquid medium is directed from circulating loop to system separating part absorbed gaseous hydrocarbon-containing medium from liquid medium. Separated part of absorbed gaseous hydrocarbon-containing medium is directed to consumer and liquid hydrocarbon-containing medium formed after desorption to circulating loop where liquid medium and liquid medium-sorbent are circulating reducing the content of absorbed gaseous medium in liquid medium, thus forming liquid hydrocarbon-containing medium-sorbent fed to liquid-and-gas jet apparatus. EFFECT: extended functional capabilities of gaseous hydrocarbon-containing medium compression and separation method and pump-ejector plant proposed for realization of this method. 8 cl, 2 dwg
