FIELD: cryogenics.
SUBSTANCE: invention relates to cryogenic equipment and can be used for liquefaction of natural gas at gas distribution stations. Plant for production of liquefied natural gas includes a high-pressure gas line with a drying unit, which is divided into a production gas line and a process gas line with a preliminary heat exchanger and an expander. Production flow line is equipped with a cleaning unit, the main heat exchanger, a reducing device and a separator with lines for supply of return gas and LNG outlet. Compression refrigerating machine evaporator, cleaning unit and "cooled production gas/reduced process gas" evaporator are installed on production gas line. After the main heat exchanger the return gas line is connected to the separation gas supply line. LNG outlet line accommodates second reduction device and second separator equipped with lines for LNG output to consumer and separation gas supply to line of reduced process gas with compressor. Compressor and refrigerating machine are connected with expander.
EFFECT: increased yield of liquefied natural gas.
