FIELD: petroleum processing. SUBSTANCE: gas-vapor mixture is pumped off from vacuum rectification column using jet apparatus. In the latter, easily condensable mixture components are condensed and non-condensable components compressed. Gas-liquid mixture is separated in separator, wherefrom gas is pumped off by jet apparatus, into nozzle of which liquid sorbent is supplied. Gas-liquid mixture is further fed into additional separator to separate gas from liquid medium. From this apparatus, gas purified by liquid sorbent is delivered to consumers, and liquid sorbent is fed into nozzle of additional jet apparatus. EFFECT: enhanced efficiency of process. 1 dwg
