FIELD: petrochemistry. SUBSTANCE: essence of the invention part concerning the method consists in that liquid working medium supplied to ejector nozzle is used in the form of liquid medium with molecular weight above 100. Mixture from ejector is supplied to profiled vessel to reduce velocity of flow of media mixture and to increase the value of static pressure. The plant for embodiment of the claimed method comprises profiled vessel. Ejector outlet is connected with inlet of profiled vessel and separator inlet with outlet of profiled vessel. EFFECT: higher efficiency. 4 cl, 1 dwg
