FIELD: liquefaction and long-term storage of gases. SUBSTANCE: gas liquefaction line in the combination system connects the mainline to a heat-insulated vessel for storage of liquefied gas and uses actuator and throttle valves. The closed line passes through a condenser of the Stirling cryogenic gas machine and comprises a Dewar flask, high-pressure pump, check valve, intermediate heat-insulated vessel with liquid nitrogen and throttle valve. The liquefied gas vapor overcondensation line is provided with a throttle valve and condensing coil-pipe located in the intermediate vessel with liquid nitrogen. The condensing coil-pipe of the gas liquefaction line is positioned in the intermediate vessel with liquid nitrogen. EFFECT: enhanced efficiency of systems, reduced material costs and enhanced safety in their service. 1 dwg
