GAS LIQUEFACTION METHOD AND APPARATUS

A stream of compressed nitrogen (or methane) at above its critical pressure is passed along conduit l0 through heat exchangers l6, l8, 20, 22 and 24, in sequence, to cool it to below its critical temperature. The resulting fluid is then subjected to expansion and resultant liquid is collected. Refri...

Zusammenfassung:	A stream of compressed nitrogen (or methane) at above its critical pressure is passed along conduit l0 through heat exchangers l6, l8, 20, 22 and 24, in sequence, to cool it to below its critical temperature. The resulting fluid is then subjected to expansion and resultant liquid is collected. Refrigeration for the heat exchangers is provided by nitrogen working fluid cycles 62, 72 and 82 employing expansion turbines 64, 74 and 84 respectively. The turbines have different inlet temperatures but substantially the same outlet temperature.
