DEVICE FOR STORAGE AND TRANSFER OF LIQUIFIED GAS Russian patent published in 1995 - IPC

FIELD: heat engineering. SUBSTANCE: two or more adsorbent cartridges 4 and 5 are connected in turn to thermal side of reverse flow line of recuperative heat exchanger 7 and to warm end of heat exchanger 6 used for removal of compression heat (cooler); each adsorbent cartridge is thermally connected with heaters 2 and 3 and reverse flow line at cold end of recuperative heat exchanger 7 is connected with reservoir (21) of using equipment by means of pipe line provided with shut-off valve. Vapors of liquefied gas formed in filling cryogenic agent storage reservoir 1, storage of liquefied gas and filling reservoir 21 are directed to adsorbent cartridge 4 where they are absorbed. When adsorbent has been saturated, it is heated by means of heater 2 and desorbed gas is cooled in cooler 6 and in heat exchanger 7, after which it is throttled in throttle 8. Liquid cryogenic agent thus formed remains in cryogenic agent storage reservoir 1 and vapors formed anew enter adsorbent cartridge 5 where they are adsorbed. Then alternation takes place in course of storage: adsorbent is heated in one cartridge and desorbed gas is throttled in other cartridge where vapors formed anew are absorbent by adsorbent. EFFECT: enhanced reliability. 1 dwg
