摘要： PURPOSE: To increase power generating efficiency per unit fuel by reforming steam of hydrocarbon with hot exhaust gas as a heating source obtained after power generation by driving a gas turbine and feeding the obtained high purity hydrogen to a fuel cell for power generation. CONSTITUTION: Outside air taken in is compressed by a compressor 2 and fed into a combustor 4. Also natural gas 3 and off-gas 9 from which hydrogen is separated are fed into the combustor 4. Burnt gas 5 generated in the combustor 4 drives a gas turbine 6, and a shaft rotating power is used for power generation. Hot exhaust gas 7 obtained after power is taken out from the gas turbine 6 is led into a waste heat recovery boiler 10, and its temperature is 400 to 650 deg.C at normal pressure. In the boiler 10, a membrane reactor 8 and a heater 14 to obtain steam used for reforming steam are installed, and heated by hot exhaust gas 7. In addition, hydrogen generated by reforming reaction in the membrane reactor 8 is fed to a fuel cell 12 as high purity hydrogen 11 by the action of the membrane, and used for power generation.

摘要： PURPOSE:To obtain high-purity hydrogen at a low reaction temp. by forming a vertical furnace with an inner cylinder, arranging an intermediate cylinder and an outer cylinder successively outside the furnace, packing an inner-layer annular space with a reforming catalyst to form a catalyst bed and providing a hydrogen-permeable tube in the bed to form a reaction/ separation region. CONSTITUTION:The heat energy necessary to a steam reforming reaction is supplied to a reforming catalyst bed 30 by a suspended combustion burner 44. The combustion gas is passed through an inner-cylinder hollow part 26 and a space demarcated by the bottom 12 of an outer cylinder 14 and an annular bottom 22 and then through an outer-layer annular space 24 and discharged to the outside from a combustion gas outlet 46. Meantime, the raw gas is passed through a raw gas inlet tube 41 and a pipe header 43, introduced into the bed 30 from the bottom of the inner-layer annular space 30 and converted to hydrogen at a high temp. The generated hydrogen is selectively separated and collected by a hydrogen-permeable tube 32 and discharged together with a sweep gas from a hydrogen outlet 52. Steam or inert gases are used as the sweep gas. Meanwhile, the unreacted raw gas is discharged outside the system from an off gas outlet 54.

摘要： PURPOSE:To permit decrease of the amt. of the steam to be directly added to gaseous hydrocarbon for reforming to a greater extent by using steam of a relatively low pressure within the same plant and evaporating the makeup water of low purity by the latent heat of condensation thereof. CONSTITUTION:The gaseous hydrocarbon (a) flowing out of a desulfurizer is first introduced into a packed column 1 and is brought into contact with circulating water in a liquid state, by which the water is evaporated and the gaseous hydrocarbon is humidified. The humidified gaseous hydrocarbon (b) is allowed to flow down in the tubes of a multi-tubular heat exchanger 2 and the circulating water is sprayed from above and is allowed to flow down the inside wall of the tubes so that both are brought into contact. Part (e) of the steam (d) generated from a methanol synthesis reactor 3 is introduced to the outside of the tubes and is condensed on the outside wall of the tubes. On the other hand, the steam (d) formed by the reactor 3 is subjected to removal of the condensed water and thereafter part thereof is introduced to the tube outside of the exchanger 2 so as to be utilized as a heat source; in addition, the other part (g) is allowed to flow down in the tubes of the exchanger 2 and is directly added to the humidified gaseous hydrocarbon (c) to makeup the deficiency of the moisture, by which the gaseous hydrocarbon (j) for reforming is obtd.

摘要： PURPOSE:To improve methanol synthetic power by providing two lines of branch tubes leading mixed gas into a space divided with an upper end plate and an upper tube sheet of reactor and installing a heat exchanger to heat up mixed gas on one of the lines. CONSTITUTION:Modified gas is mixed with discharged gas composed of the recycled gas taken out of a gas outlet nozzle 9 of a reactor 1 and heated up by a compressor K2, and fed into the reactor 1. The gas reaching the point M is operated by closing FCV-2 and FCV-3, or in other words, by making the flow rate zero and opening FCV-1, during the normal stationary operation. That is, the total gas volume is fed from the lower section of the reactor 1 into a space A rising up inside a plurality of internal tubes 14. When catalyst activity is large or CO/H2 is large, the opening degree of FCV-2 is so adjusted as to flow a proper flow of unreacted gas of the temperature at the point M from an upper section gas inlet nozzle 10 into an upper section space B through a tube system.

摘要： PURPOSE:To purify an ultraviolet ray irradiation chamber within a short time, by providing a liquid jet nozzle and a wiper to the inside periphery of the irradiation window of a reactor for treating exhaust gas by the irradiation of ultraviolet rays and providing a wiper driving part outside the reactor. CONSTITUTION:A liquid jet nozzle 12 and a wiper 10 are provided to the inside periphery of the irradiation window (synthetic quarts glass plate) 4 of a reactor 1 for treating exhaust gas by the irradiation of ultraviolet rays and a drive part 7 for sliding the wiper 10 is provided outside the reactor 1 to constitute a purifying chamber. Therefore, even when the dust in exhaust gas or a reaction product such as ammonium sulfate due to the irradiation of ultraviolet rays is adhered to the inner surface of the quartz glass plate 4, water is injected from the liquid jet nozzle 12 to make it possible to wash off the greater part of the adhered dust or reaction product. Further, when the wiper 10 is operated while water is injected, the adhered substance remaining after washing can be removed.

摘要： PURPOSE:To reduce the wt. of a reactor, by connecting a compressed gaseous mixture header and a reaction finished gas header to the upper and lower ends of a large number of reaction tubes fixed and supported by a support plate and a buffle plate. CONSTITUTION:In a multitube reactor for the synthesis of methanol, the unreacted gas introduced from a gas introducing pipe 11 is guided to each reaction tube 6 from an upper header 14 and contacts the catalyst 7 in said tube 6 to generate reaction and taken out to the outside as reaction finished gas through a lower header 15. Further, each reaction tube 6 is supported by a support plate 4 provided with steam and water moving holes 25 and a lower buffle plate 5. When the synthetic reaction of methanol is performed using a copper-based catalyst and the pressure of pressurized water having saturation temp. contacting the outer surface of each reaction tube 6 is considered to become about 40 atm., the body, lower bottom and upper cover of this reactor are reduced in a thickness to a large extent and, since a tube plate is not provided especially, the wt. and cost of the reactor are reduced in an extremely effective manner.
