摘要： PROBLEM TO BE SOLVED: To preheat a highly combustible fuel and an oxidizing substance thereof while ensuring effective operation in safety by arranging a tubular oxidizing gas passage in a shell such that an oxidizing gas is received from the inlet and discharged from the outlet. SOLUTION: First heat exchanging fluid, e.g. high temperature medium, carrying combustion exhaust gas or waste heat is introduced into a shell 12 through an inlet 42. The first heat exchanging fluid passes through a passage formed by a baffle 40 and traverses the shell 12 thence exits therefrom through an outlet 44. A second heat exchanging fluid, e.g. an oxidizing gas, being heated in a heat exchanger 10 enters into an inlet end cap 14 from an inlet 46. The second heat exchanging fluid enters into a tube bundle 36 and passes through a parallel spaced tube 38 while being heated by the first heat exchanging fluid passing the shell side of the heat exchanger 10. The second heat exchanging fluid finally enters into an outlet end cap 18 from the tube bundle 36 and exits the heat exchanger 10 through an outlet pipe 48.

摘要： PURPOSE: To clean elongated objects having contaminated surfaces while averting environmental pollution by exposing the elongated objects having the contaminated surfaces to a gaseous, liquid and/or solid inert gas to embrittle the contaminants, then drawing out the elongated objects through an orifice and removing the embrittled surface contaminants. CONSTITUTION: The elongated objects 11 the surfaces of which are contaminated by the contaminants including organic or inorganic substances containing oxides, filth, lubricants, lime, carbon-containing and graphite substances are exposed to the gaseous, liquid and/or solid inert gas of the amount suitable for embrittling the contaminants in a chamber 10. The elongated objects 11 are thereafter drawn out through the orifice 17 of a die 16 to remove the embrittled surface contaminants from the elongated objects 11. The inert gas is selected from the group consisting of liquid nitrogen, liquid argon and solid carbon dioxide. After the contaminants are removed, the elongated objects 11 are subjected to annealing in an inert atmosphere. This orifice 17 has a cross section substantially the same as the cross section of the elongated objects 11.

摘要： PROBLEM TO BE SOLVED: To provide an ion purifying apparatus and method suitable for supplying an ultrapure chemical reagent to semiconductor fabrication process. SOLUTION: The invention provides an ion purifying apparatus and method suitable for supplying an ultrapure chemical reagent to a semiconductor manufacturing process. The ion purifying apparatus is provided with a vapor inlet for introducing the vapor of a chemical reagent to be purified into. Highly pure water is continuously introduced into a tower through a highly pure water inlet. The highly pure water is brought into contact with the vapor of the chemical reagent, so that purified chemical reagent vapor and polluted water are produced. The purified chemical reagent vapor is discharged out of the column through a vapor outlet. The polluted water is discharged out of the column through a liquid outlet. The invention is especially useful for the semiconductor industry.

摘要： PROBLEM TO BE SOLVED: To improve efficiency and safety even in a method wherein not only carbon dioxide and nitrogen are used but also liquid air can be utilized, by controlling the ratio of liquid nitrogen to liquid oxygen in accordance with the amount of detected oxygen. SOLUTION: The amounts of liquid, supplied from a liquid nitrogen supplying source 22 and a liquid oxygen supplying source 24, are controlled by a nitrogen flow control valve 26 and an oxygen flow control valve 28. In this case, the valves 26, 28 can be controlled by a control unit 30 to realize a desired low- temperature mixture containing 18-25% of oxygen. Further, the valves 26, 28 can be controlled manually. In order to guarantee a safe working condition for a worker in a room, wherein a freezing device is installed, one or plurality of sets of oxygen detectors 32 are arranged in the room. In this case, the control unit 30 can use information from the oxygen detector 32 to control the mixture of nitrogen and oxygen by changing a flow rate employing the valves 26, 28 when it is required.

摘要： PROBLEM TO BE SOLVED: To provide a new method for separating and purifying a mixture of perfluoro compounds(PFC's) to satisfy the requirement of a semiconductor manufacturing industry and overcome incompleteness of a related technique, especially a method for treating a discharged flow from a semiconductor-processing tool. SOLUTION: This method for separating and purifying a mixture of PFC's comprises (a) a step for introducing a perfluoro compound-containing gas flow into a first distillation column, (b) a step for taking out the light product from the first distillation column and taking out the heavy product from the first distillation column, (c) a step for introducing the light product from the first distillation column to a second distillation column, (d) a step for taking out the light product from the second distillation column and taking out the heavy product from the second distillation column, (e) a step for introducing the light product of the second distillation column to a third distillation column and (f) a step for taking out the light product from the third distillation column and taking out the heavy product from the third distillation column. The method is effectively used for treatment of a waste gas from a semiconductor processing tool, and the PCF is cyclically used without discharging the PCF to the environment.

摘要： PROBLEM TO BE SOLVED: To improve thermal efficiency of a boiler, by a method wherein oxygen contained in at least one level of air in the level of secondary air or a level higher than the secondary air is enriched, in a black liquor recovery boiler equipped with at least two levels of air injection. SOLUTION: Primary air 2 is introduced into a boiler 1 in a level A, secondary air 3 is introduced in a level B and tertiary air 4 is introduced in a level C, respectively, while a liquid gun for injecting black liquor is arranged in a level D. Further, a superheating unit 5, a boiler bank 6 and an economizing device unit 7 are provided continuously above the boiler 1. Upon operating such a boiler 1, combustion oxidizing agent is injected under secondary air or the same level to increase the concentration of oxygen from 21% into the degree of 30% in order to effect the complete combustion of the black liquor. According to this method, necessary air is reduced and the thermal efficiency of the boiler 1 is improved. The third level is preferably arranged at the same level as or near that of the injection port of the black liquor.

摘要： PROBLEM TO BE SOLVED: To effectively remove metal impurities from corrosive liquefied gas by transferring the liquefied gas in a gas phase state when the corrosive liquefied gas is filled from a feed vessel to a receiver. SOLUTION: A feed vessel 102 is arranged in a heating tank 106 and is in an equilibrium state prior to start. A receiver 104 is cooled and is also in an equilibrium sate. The feed vessel 102 and the receiver 104 are connected each other through a gas line 116. A gas line 124 is connected to a gaseous nitrogen supply source 130. A gas line 134 is connected to an evacuating device 140 and a scrubber 146. A valve 138 is opened and a device 100 is purged in vacuum several times to completely remove air inside it. Then, the valve 138 is closed, a valve 144 is opened and a part of gas is sent to the scrubber 146 to regulate the condition inside the device 100. After that, the valve 144 is closed and corrosive gas is vaporized in the feed vessel 102 and is sent to the gas line 116. The corrosive gas enters the receiver 104 and is cooled and recondensed in the receiver 104.
