FIELD: machine building.
SUBSTANCE: for liquefaction of natural gas there is used throttle recuperative procedure with auxiliary circuit of cooling on base of main vortex pipe and with simultaneous utilisation of hot flow of auxiliary vortex pipe for heating equipment taken out of operation. A chamber of power division of the main vortex pipe is subjected to additional cooling with a cooling agent undergoing phase transformations: boiling at withdrawal of heat from the vortex pipe and condensation at emission of heat to an external heat carrier; cold flow in the auxiliary vortex pipe is used as a heat carrier, whereto heat is emitted at condensation of cooling agent.
EFFECT: complete utilisation of cold in cold flow of auxiliary vortex pipe; due to external cooling chamber of power division of main vortex pipe its cold flow has minimal possible temperature.
