FIELD: gas industry.
SUBSTANCE: invention relates to the gas industry and can be used in the organization of the process of liquefaction of natural gas. The plant for the production of liquefied natural gas is connected to a natural gas supply source and includes a connected booster compressor, pre- and final cooling heat exchangers, a drying unit and a cleaning unit. The main pipeline with a natural gas flow is divided into a production flow pipeline and a process flow pipeline. The process flow pipeline passes through the first control valve, the process ejector, the final cooling heat exchanger, the pre-cooling heat exchanger and to the outlet for supply to the consumer. The production flow pipeline passes through a second control valve, a production ejector, a pre-separation separator, a choke and a final separation separator. The steam phase pipeline from the pre-split separator is connected to the inlet of the suction chamber of the process ejector, and the steam phase pipeline from the final separation separator is connected to the inlet of the suction chamber of the production ejector.
EFFECT: saving energy and increasing the energy efficiency of the LNG production process.
