Abstract

A set of inventions relates to liquefaction of gases and their mixtures and can be used during natural gas processing. The technical result reached through the application of the inventions is lower consumption of power needed during the natural gas liquefaction process. The technical result is reached through the use of the mixed coolant at the precooling and liquefaction stages as well as the nitrogen cycle at the supercooling stage. The foregoing formula consists of two independent claims.
