ABSTRACT:
The liquefaction process comprises the stages of pre-cooling (3) the gas, of cooling it by heat exchange (6, 7, 8) and by fractional expansion (10, 11), under supercritical conditions, then of expanding it in a turbine (9) which delivers a volume of subcooled liquid (2). The process is especially applicable to the refrigeration of superconductive elements.
