METHOD OF FILLING RESERVOIR WITH COMPRESSED GAS Russian patent published in 1999 - IPC

FIELD: cryogenic engineering; methods of filling reservoirs with compressed gases through regasification of liquefied gas. SUBSTANCE: liquefied gas supplied from cryogenic reservoir is heated by passing it through atmospheric and recuperative heat exchangers. Liquefied gas is evaporated due to heat exchange with atmospheric air; cold vapor is passed through recuperative heat exchanger and is compressed by of means of compressor; part of compressed gas or discharged for recuperative heat exchange with cold vapor. For pumping the gas, use may be made of only compressor due to delivery of colder dense vapor to its inlet. EFFECT: enhanced efficiency. 3 cl, 1 dwg
