  • Method of obtaining refrigeration at cryogenic level
    Patent number: 4189930
    Abstract: A method of obtaining refrigeration at a cryogenic level comprising a gaseous fluid fed in the form of an incoming stream to sustain a refrigerative load. The incoming stream is stepwise cooled and expanded with liquefaction. The liquid fluid formed is used to sustain a refrigerative load, evaporating as a consequence, and the vapour constitutes a return stream which is adiabatically compressed so as to attain a temperature close to the temperature of the incoming stream before the liquefaction thereof.
