FIELD: separation of gas-liquid flows. SUBSTANCE: separation of the source gas-liquid flow in the process of conversion of hydrocarbons in presence of hydrogen containing liquid hydrocarbons and hydrogen involves separation of initial flow in the first separation zone into the first liquid phase and the first vapor phase, cooling the produced first vapor phase to a temperature from 25 to 85 C, and separation of the cooled vapor phase in the second separation zone, essentially at the same pressure as that in the first zone, separation into the second liquid phase and the second hydrogen-rich vapor phase, separation of the first liquid phase in the third separation zone, essentially at the same temperature as in the first separation zone and pressure below 60 bar (6 MPa) into the third liquid phase and third vapor phase, and separation of the second liquid phase in the fourth separation zone, essentially at the same temperature as in the second separation zone and at a pressure below 60 bar (6 MPa) into the fourth liquid phase which is discharged, at least partly, in the form of the end product, and the fourth vapor phase, conducting the process in the first separation zone at temperature from 200 to 350 C so as to produce 25-75 wt.-% of the outcome flow in the first vapor phase. EFFECT: higher efficiency. 9 cl
