Abstract

An apparatus for cooling and liquefying a gaseous mixture by means of a refrigerant fluid formed of a plurality of constituents, comprising a gas compressor, a plurality of tanks for separating gas from liquid and two series of counter current exchangers, said exchangers, for the cooling and liquefaction, being placed at increasing heights so as to provide for a circulation by gravity, along the various exchangers, of the refrigerant liquid injected at the head of each exchanger, and its mixture with the refrigerant gases, said refrigerant gases being liquefied by successive fractions at lower and lower temperatures in a first one of said two series of exchangers and used for cooling and liquefying the gaseous mixture in the other one of said series of exchangers, wherein in at least one series of exchangers at least the exchangers working at the two lowest temperatures are forming part of a unitary assembly in which the refrigerant fluid circulates downwardly, whereas in the other exchangers the refrigerant fluid circulates upwardly.
