FIELD: protracted storage of liquefied gases. SUBSTANCE: system includes closed nitrogen loop with cryogenic Stirling machine, check valve, heat-insulated reservoir filled with liquid nitrogen and throttle valve. Each liquefied gas vapor recondensation loop consists of heat-insulated reservoir for storage of liquefied gas, safety valve, throttle valve, adjusting valves fitted respectively before and after liquid nitrogen reservoir and check valve fitted before liquefied gas storage reservoir. Recondensation loops have common condensing coil located in liquid nitrogen reservoir. EFFECT: enhanced efficiency; reduced cost. 1 dwg
