FIELD: generation of gases.
SUBSTANCE: invention relates to cryogenic equipment and can be used in the gas industry for liquefying natural gas. Proposed is a plant including a booster compressor 2, a purification and drying unit 3, a multi-flow heat exchanger 4, an integrated refrigerating machine with a multicomponent cooling agent, including a compressor 5, a refrigerator 1, and a reducing apparatus 6, also reducing apparatus 7, a separator 8, a compressor 9. The separator 8 is connected with the natural gas line after the purification and drying unit 3 by a separation gas removal line with the reverse stroke of the heat exchanger 4, the junction of the fuel gas removal line 16 connected with the compressor drive, and the compressor 9, located thereon consecutively. The booster compressor 2, compressor 5 of the integrated refrigerating machine, and separation gas compressor 9 are connected with the drive 10, also connected with an additional refrigerating machine 11, connected in turn by the cooling agent input/removal lines with the refrigerator 1.
EFFECT: reduction in the specific power consumption.
