FIELD: machine building.
SUBSTANCE: separation method of one or more C2+hydrocarbons from liquid hydrocarbon flow involves supply of hydrocarbon raw material flow with mixed phases in the form of partially evaporated hydrocarbon raw material to the first gas-liquid separator. Hydrocarbon raw material flow with mixed phases is received from one or more storage tanks by means of passing through the heat exchanger of liquid hydrocarbon flow from one or more storage tanks. Then, flow of hydrocarbon raw material with mixed phases is separated in the first gas-liquid separator into the first gaseous flow leaving the first outlet and at least one liquid flow C2+. The first gaseous flow is passed through the compressor, and as a result, compressed flow is obtained, which is cooled in one or more heat exchangers, and as a result, flow of at least partially condensed hydrocarbon products is obtained. The second gaseous flow is added to the flow after the first outlet. The second gaseous flow includes evaporated gas accumulated from one or more storage tanks for liquid hydrocarbons in gaseous form.
EFFECT: use of the invention will allow effective use of evaporated gas formed at storage.
