摘要： PURPOSE:To reduce power required at the time of liquefaction by cooling refrigerant for cycle due to heat exchange in a refrigerant heat exchanger and keep the temperature on the outlet side of a cooling vessel high at the time of gasification by returning refrigerant for cooling which is warmed due to heat exchange into the cooling vessel at the same time to reduce power required. CONSTITUTION:Refrigerant for cycle which circulates in a freezing cycle 23 is introduced into a heat exchanger for liquefaction 20, and gas is cooled for the purpose of liquefaction due to heat exchange with this refrigerant. On the other hand, a cooling vessel 10 is connected with a refrigerant circulating device 33 consisting of a refrigerant pump 34 and a refrigerant passage 36. A refrigerant heat exchanger 32 is provided on the halfway of the refrigerant passage 36. That is, in this device, refrigerant for cooling 14 which circulates in the refrigerant passage 36 and refrigerant for cycle which circulates in the freezing cycle 23 exchange heat each other in the refrigerant heat exchanger 32. Consequently, it is possible to reduce power which is required at the time of both liquefaction and gasification.

摘要： PURPOSE:To effectively freeze a cold storage medium around a heat transfer pipe in a short time by forming each heat transfer pipe with a tube through which the heat storage medium flows and a plate fin, and configuring the plate fin such that an envelope line connecting the tip ends of the plate fins is a polygon with the length of each side being the same as the length of one side of the other adjacent heat transfer pipe, and further disposing the heat transfer pipes such that one sides of the heat transfer pipes are parallel to each other. CONSTITUTION:Heat transfer pipes 11 are formed by protruding a plurality of plate fins 13... located successively in the length direction of a tube 12 along the outer periphery of the tube 12 such that an envelope 14 connecting the tip ends of the plate fins is square. The heat transfer pipes are disposed in a cold storage such that each side of a square is parallel to one side of the other adjacent heat transfer pipes 11.... With such construction, valley parts are unlikely to receive cold among the heat transfer pipes 11... are prevented from being produced and the peripheries of the heat transfer pipes 11... uniformly receive the cold heat, so that the cold storage medium around the heat transfer pipes can be effectively frozen in a short time.

摘要： PURPOSE:To secure as much production volume in the nighttime operation as in the daytime operation and save the power consumption to drive a compressor by increasing he flow rate of the high pressure nitrogen gas to an LNG heat exchanger when the liquefied natural gas supply rate drops, and decreasing same when the liquefied natural gas supply rate increases. CONSTITUTION:A circulated nitrogen compressor 21 consists of a low pressure stage compressor 22 and a high pressure stage compressor 23. The high pressure stage compressor 23 comprises a first compressor 23a which is operated day and night and a second compressor 23b which is operated only at night, which are parallelly connected. Therefore, during the daytime when the LNG supply rate is high, a small quantity of high pressure nitrogen gas is supplied to an LNG heat exchanger 24 by means of the first compressor 23a, and the coldness in the low temperature range where the exergy of LNG is great is used to cool the high pressure nitrogen gas. Meanwhile, during the nighttime when the LNG supply rate is low, the high pressure nitrogen gas is supplied to the LNG heat exchanger 24 at a large flow rate by means of both the first and second compressors 23a, 23b. Because the flow rate of the high pressure nitrogen gas to the LNG heat exchanger 24 is so increased, the coldness retained by LNG can be used not only in the low temperature range but also in the high temperature range.

摘要： PURPOSE:To reduce the installation cost of a rectification device and a cold box by a method wherein the total amount of internal circulating liquid, produced by a main evaporator, is supplied to the top of a low-pressure tower while only external circulating liquid is supplied to a high-pressure tower. CONSTITUTION:A rectification device D is constituted of a high-pressure tower 6 and a low-pressure tower 7, which are provided in parallel in a cold box C. Nitrogen gas, separated from material air in the high-pressure tower 6, is sent into a main evaporator 8 through a nitrogen gas introducing line 12 and, at the same time, is liquefied by an external circulating line 9 to return it into the liquid nitrogen receiver 10 of the high-pressure tower as external circulating liquid. Liquefied air, separated from the material air, is sent into the intermediate part of the low-pressure tower through a liquefied air introducing line 13. The liquefied air is separated in the low-pressure tower 7 into liquefied oxygen and nitrogen gas while the nitrogen gas is liquefied by a liquefying line 16 and is taken out to the outside of the title device as the product of liquefied nitrogen.
