The opportunity application of a cryogenic cycle with the thermal machine for liquefaction of natural gas is turned out under pressure 50-70 bars which is characteristic for main gas pipelines is considered. On example of throttle methane liquefier the opportunity to improvement its power parameters by application the thermal machine and thermal converter is considered. Use of the thermal machine in structure of thermal converter with general COP 16 % allows to raise liquefaction factor of throttle methane liquefier on 390 %.

Key words: cryogenic engineering, thermodynamic losses.
