Foerg, W

A process is described for the liquefaction of natural gas by heat exchange, initially with a first multicomponent mixture and thereafter with a second multicomponent mixture, each of these mixtures, respectively in a closed refrigeration cycle, being compressed, at least partially liquefied, and expanded, characterized in that the first multicomponent mixture, after the partial liquefaction thereof, is subjected to a phase separation; that the thus-obtained liquid fraction, after its expansion, is at least partially evaporated in heat exchange with media to be cooled comprising the natural gas, the gaseous fraction obtained during the phase separation, and the second multicomponent mixture; and that the gaseous fraction, liquefied in heat exchange with the expanded liquid fraction, is expanded and at least partially evaporated in heat exchange with the natural gas and with the second multicomponent mixture, which latter is at least partially liquefied during this heat exchange.
