FIELD: liquefaction and storage of gases. SUBSTANCE: gas liquefaction line in the universal plant connects the mainline to a heat-insulated vessel for storage of liquefied gas and uses a throttle valve and an intermediate heat exchanger. The closed nitrogen line passes through the intermediate heat exchanger. The heat-insulated vessel is made with a nitrogen screen connected to the condenser of the Stirling cryogenic machine through a closed-circuit liquid line with a Dewar flask, high-pressure pump and a check valve positioned in it. The condensing coil-pipe of the gas liquefaction line is located in the area of the nitrogen screen. EFFECT: enhanced efficiency and reduced costs at production, storage and use of liquefied gases. 1 dwg
