FIELD: distillation technics; petroleum processing. SUBSTANCE: liquid medium is fed, as active medium, into jet apparatus, in flow part of which, vapor-gas phase is mixed with liquid medium and condensing components of the former are transferred into liquid state. Resultant gas-liquid mixture is fed into separator, wherefrom, after separation, liquid phase is pumped into jet apparatus. Meanwhile, side distillate from atmospheric column is fed into active liquid medium circuit. Invention is chiefly aimed at processing petroleum materials. EFFECT: intensified distillation of liquid product and reduced power consumption. 2 cl, 1 dwg
