TECHNOLOGICAL COMPLEX AIR LIQUEFACTION Russian patent published in 2000 - IPC

Abstract RU 2154786 C1

FIELD: air liquefaction complexes. SUBSTANCE: air is liquefied in compressor and after cleaning it of admixtures air is cooled in counter-current heat exchanger and is expanded in throttle valve. Liquid air thus obtained is drained into reservoir. Remaining part of noncondensed air is cooled down and liquefied due to heat exchange with liquid nitrogen flowing through nitrogen loop includes Stirling cryogenic machine, Dewar flask, high-pressure pump, coil, counter- current heat exchanger, throttle valve and expansion reservoir. EFFECT: enhanced efficiency; increased liquefaction coefficient. 2 cl, 1 dwg
