FIELD: gas transportation equipment.
SUBSTANCE: invention relates to gas transport equipment and can be used in gas processing industry, in particular in liquefaction of natural gas, ensuring improvement of anti-icing and recuperation systems of gas transfer units. Gas-pumping unit comprises gas turbine engine, centrifugal compressor, integrated air-cleaning device with anti-icing system, gas-slug circuit with exhaust gases heat recovery system, which includes recuperative heat exchanger, wherein gas turbine engine fuel used for liquefaction is used, mutually supplementing independent anti-icing system and circulating air heating system are used as anti-icing system, in system of heat recovery of waste gases high-temperature organic heat carrier is used.
EFFECT: higher economic efficiency and reliability of operation.
