摘要： PURPOSE:To perform heat exchanging even under a high pressure of source gas by providing a plate fin type compact heat exchanger, a vessel in which the compact heat exchanger is housed to maintain airtightness and means for introducing pressure gas to the vessel to apply external pressure to the compact heat exchanger. CONSTITUTION:A cold reserving box 3 is formed with a pressure-proof vessel with airtightness in which a heat exchanger 4 connected to a source gas supply line 1a and a gas/liquid separator 5 are housed and to the outer wall of which an N2 gas supply line 4a and a discharge line 4b are connected. Upon heat exchanging, high internal pressure is applied to the heat exchanger 4 because of the supply of high pressure source gas. In order to meet it, pressure N2 gas is supplied to the cold reserving box 3, so that large internal and external pressure difference applied to the wall of the heat exchanger is reduced. Accordingly, even when the pressure of the supplied source gas exceeds 100kg/cm G, the compact heat exchanger excellent in heat transfer performance can be used.

摘要： PURPOSE:To more effectively cool raw material synthesis gas by supplying low temperature fluid passed through an expansion turbine again to a heat exchanger as for cooling the synthesis gas. CONSTITUTION:Liquid separated and stored in a bottom of a gas/liquid separator 3 is discharged through a route L31, adiabatically expanded by an expansion valve 4 provided on the way to be lowered at its temperature by a Joule- Thomson effect to become initial low temperature fluid, which is heat exchanged with raw material synthesis gas in a heat exchanger 2. The fluid in the route L31 is once discharged out of the exchanger 2 to perform an adiabatic expansion in an expansion turbine 5, further cooled to become secondary low temperature fluid, which is again passed through a route L32, heat exchanged with the gas in a route L1 in the exchanger 2, then heated, and discharged out of a system as off gas.

摘要： PURPOSE:To restrict an amount of nitrogen discharged out of a system of an air separating device as much as possible and improve a recovering efficiency of product nitrogen. CONSTITUTION:In a nitrogen manufacturing device 1 in which nitrogen is separated from raw material air by a low temperature processing and refined by it, a refining device 3 is divided into a refining tower 31 in which raw material air is refined, liquid nitrogen is transferred over the refined air and liquid air having much of oxygen at the bottom part, and a main condensing part 32 in which liquid oxygen is stored at its bottom part, and a main distilling unit 33 for condensing nitrogen supplied from the refining tower 31 through a heat exchanging with the liquid nitrogen is internally installed. A passage L10 is formed for circulating the liquid air with rich oxygen from the bottom part of the refining tower 31 through an expansion valve 36 to a main condensing part 32. A reboiling unit 5 for applying heat for liquid air refining operation is arranged at a lower location than a raw material air supplying position in the refining tower 31. Off-gas fed out of a top part of the main condensing part 32 is heat exchanged with the raw material air at the main heat exchanger 2 and heated by it, thereafter the gas is supplied as the heat source for a refining operation.

摘要： PURPOSE:To reduce an operating pressure in a pressure tower without any trouble. CONSTITUTION:Heat exchange is effected between material air and liquid oxygen in the bottom of a low pressure tower in an evaporator 14 to cool it while the cooled material air is introduced into a pressure tower 11 whereby a temperature in the pressure tower is reduced. On the other hand, liquid nitrogen, obtained by condensing nitrogen gas in the top section of the pressure tower 11 by a condenser 20, is passed through the condenser 20 again through a nitrogen transfer passage 24 to heat it by heat exchange between the nitrogen gas in the condenser 20 and, thereafter, is introduced into a low pressure tower 12 whereby a temperature in the low pressure tower 12 is increased.

摘要： PURPOSE: To increase the extraction quantity of the liquid N2 by sucking the outlet gas of an expansion turbine by a load blower to increase the differential pressure between the inlet gas and the outlet gas of the expansion turbine and increase the cold. CONSTITUTION: The exhaust gas is introduced as the inlet gas of an expansion turbine 4 by an extraction pipe 67, and the expansion turbine 4 is operated by the exhaust gas. Because a load blower 41 is also operated by this operation, the outlet gas of the expansion turbine 4 is sucked into the load blower 41 through a main heat exchanger and an exhaust pipe 60, and as a result, the outlet gas of the expansion turbine 4 is dropped in pressure. The outlet gas of the expansion turbine 4 is dropped in pressure through the adiabatic expansion at the expansion turbine 4, and also dropped in pressure through the suction at the load blower 41. The differential pressure between the inlet gas and the outlet gas at the expansion turbine 4 is larger than that in a case of only the pressure drop caused through the adiabatic expansion at the expansion turbine 4 in a conventional nitrogen manufacturing device, and the cold is also increased, and the extraction quantity of the liquid N2 can be increased.

摘要： PURPOSE:To enhance economical efficiency by preventing a liquid shortcircuiting falling phenomenon, by arranging perforated plates in a multi-stage fashion so that the depth of the liquid in the liquid outlet part of each perforated plate becomes larger than that in the liquid inlet part thereof. CONSTITUTION:A stepped part is formed in the side of the outlet wire of a plate 2' so as to make the liquid depth Ho of a liquid outlet part larger than the liquid depth Hi in the side of an inlet weir 5, that is, a liquid inlet part. Therefore, when a steam speed is lowered by throttling a steam flow amount at the time of weight reduction operation, weeping is collectively generated in the liquid outlet part and a liquid is fallen to the liquid inlet part of the nxt lower plate and gas-liquid contact can be sufficiently performed on the plate and predetermined capacity can be kept.
