FIELD: cryogenics.
SUBSTANCE: invention relates to cryogenic engineering and can be used in gas industry for liquefaction of natural gas. Proposed is a station that includes a purification unit located on the natural gas line, a compressor driven by an internal combustion engine, connected to the chiller, the pre-cooling unit with external and own refrigerants, separation gas and part of process gas, a re-cooling unit with separation gas and reduced process gas, after which the natural gas line is branched into a process gas line with a reducing device and a product gas line with a device for reducing and separating. Wherein the purification unit is connected to the pre-cooling unit by a feed line of heated separation gas, and the drive is connected to the cleaning unit by the fuel gas supply line and to the chiller with a heat transfer line. Chiller is connected to the pre-cooling unit by the refrigerant supply line.
EFFECT: high output of liquefied natural gas.
