摘要： PROBLEM TO BE SOLVED: To sufficiently reduce noise and enable the exhaust of a large amount of high pressure air. SOLUTION: This noise reducer uses an absorbing wall to absorb the noise generated when high pressure air is exhausted outside by being blown through a small holes 1a. In this case, the noise reducer has the following: a cylindrically shaped high pressure air blowing body 1 in which one end is sealed and has small holes 1a on the periphery thereof through which high pressure air is blown out; a cylindrically shaped outer cylinder noise reducer 4 which has a noise absorbing wall 21 opposing the peripheral surface of high pressure air blowing body 1, with one end of the absorbing wall 21 open so that the high pressure air is exhausted outside therethrough; and an inner cylinder noise reducer 3 which is installed at one end of the high pressure air blowing body 1 so as to be located inside the outer cylinder noise reducer 4, and is provided with an noise absorbing wall 20 along the inner wall surface of the outer cylinder noise reducer 4.

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.

摘要： PROBLEM TO BE SOLVED: To exhaust a lot of high-pressure gas while sufficiently reducing noise, and to prevent degradation of noise absorbing performance and a break when the high-pressure gas spouts. SOLUTION: This silencer has a tube-like high-pressure gas spout body 1 sealed at one end, having fine holes 1a spouting high-pressure gas on the peripheral face, and a tube-like outer tube silencing body 4 having a noise absorption wall 21 disposed in parallel to the peripheral face of the high-pressure gas spout body 1, opened such that one end of the noise absorption wall 21 exhausts the high-pressure gas outside. The outer tube silencing body 4 houses a noise absorption member 16 absorbing noise, and has plural noise absorption chambers 33 allowing the noise to reach the noise absorption member 16 through hole parts 18a. The noise absorption chambers 33 are distributed in the exhaust direction of the high-pressure gas such that a pressure difference in each noise absorption chamber 33 is below a prescribed value not allowing deformation of the noise absorption member 16 by the high-pressure gas flowing in through the hole part 18a.

摘要： PURPOSE:To reduce the total power of a compressor by a method wherein material air is pressurized to a pressure necessary for adsorbing operation in an adsorbing tower at the inlet side of the adsorbing tower and, further, is pressurized to a pressure within a limit pressure capable of effecting rectification operation in the high-pressure tower of a rectifying tower at the outlet side of the adsorbing tower. CONSTITUTION:Material air from a material filter 1 is pressurized by a primary material compressor 21 to a pressure (5kg/cm g) necessary for adsorbing operation in an adsorbing tower 3 while the material air from the adsorbing tower 3 is pressurized by a secondary compressor 22 to a pressure (10kg/cm g or less, for example) within a limit pressure capable of effecting rectification operation in a high-pressure tower 71 for a rectifying tower 7. Accordingly, the operating pressure of the high-pressure tower 71 becomes same as the delivery pressure of the secondary material compressor 22 in the case of this device.

摘要： PURPOSE:To increase an amount of separated and recovered liquid nitrogen (LN2) to a value higher than that of liquid oxygen (LO2) and to reduce consumption of a power caused by the separation of liquid by a method wherein a heating means to vaporize a nitrogen component in liquid raw material air is mounted to the bottom part of a lower tower, and the lower tower is connected to a main heat exchanger so that raw material air cooled by the main heat exchanger is fed to a position at a stage higher than that of the heating means of the lower tower. CONSTITUTION:In a lower tower 41, by heating raw material gas fed to the lower tower 41 by means of flush gas from a reboiler 44, the raw material gas is separated into N2 and mixture liquid of O2 and Ar substantially not containing N2. This separation enables an approximate whole amount of N2 contained in the raw material gas to be taken out as a product LN2 and reflux LN2. This constitution enables the increase of the product LN2 capable of being separated and recovered.
