摘要： PURPOSE:To remarkably reduce the adsorption time of the subject adsorber by superposing the passages formed by partition plates provided with a heat- transfer fin on one another so that the direction of one fin crosses that of the other fin. CONSTITUTION:The gas 6 to be treated is introduced into a passage 4B for the gas to be treated, the materials in the gas are adsorbed by the adsorbent 3 while the gas passes through the passage 4B, and the refined gas 7 is discharged. The adsorbent 3 having adsorbed the materials is heated by a heating medium 5 flowing in the heating medium passage 4A, the adsorbate is desorbed, and the adsorbent is cooled and regenerated. Since the heating area is increased by the heat-transfer fins 2A and 2B provided in the passages 4A and 4B, cooling and heating are efficiently carried out, and a uniform temp. distribution is obtained in a short time. As a result, the size of an adsorption tower can be remarkably reduced.

摘要： PURPOSE:To improve the yield of a gaseous product by storing an adsorption after gas formed in an adsorption stage in a storage tower, introducing the adsorption after gas in the direction opposite to the feed gas flow in the adsorption stage, and pressurizing the after gas. CONSTITUTION:The adsorption after gas is introduced from a tank 3 into the tower 4 wherein a pressure reducing state is finished, raw gas is introduced from a tank 1 into an adsorption tower 5 wherein a pressure increasing stage is finished, the desired component is adsorbed, and the adsorption after gas is stored in the tank 3. The gaseous product is introduced by a blower 8 into a tower 6 wherein an adsorption stage is finished from a tank 2, the gaseous impurities are purged, and the purge after gas is returned to the tank 1 and reutilized. A tower 7 wherein a gaseous product purge stage is finished is sucked by a vacuum pump 9, and the desired component is desorbed and introduced into the product tank 2. These stages are successively carried out in the respective towers, and the gaseous product is continuously obtained.

摘要： PURPOSE:To reduce the energy required for separating and recovering concd. CO by separating the reformed gas obtained by the reaction of hydrocarbons with steam and gaseous CO2 by pressure-swinging adsorptive separation. CONSTITUTION:The hydrocarbons 6 are introduced into a reforming furnace 1 along with a CO2-rich gas 7 as the by product, allowed to react with steam 8 in the presence of a reforming catalyst 3, and reformed to obtain the reformed gas 9 contg. H2, CO2, CO, CH4, etc. The reformed gas 9 is then introduced into a pressure-swinging adsorptive separator(PSA) device 4, and separated into the gas 7 and a gaseous mixture of CO and H2. The gas 7 is returned to the furnace 1, and the gaseous mixture is separated into high-purity gaseous CO 10 and an H2-rich gas 11. The gaseous CO 10 is recovered as a product, and a part of the gas 11 is supplied to the furnace 1 along with the air 12, burned, and used as the heat source necessary for the reforming reaction. The remainder is supplied to a gas-turbine generator 5, and used as the power source.

摘要： PROBLEM TO BE SOLVED: To provide a pressure variation adsorption tower capable of increasing a thermal efficiency in the same device structure as conventional one and capable of efficiently separating and recovering an objective component without necessitating a special device and the huge energy. SOLUTION: In the pressure variation adsorption tower of an adsorption separation device, the objective component in a mixed gas is separated and recovered by properly combining an adsorption stage, a blow down stage, a pressure equalization stage, a purge stage, a desorption stage and a pressurizing stage by using the adsorption tower 1 provided with a bed 2 filled with an adsorbent. In such a case, a filled layer 5 is formed by filling an inert filler in space parts at both ends of the bed 2 filled with the absorbent and provided in the adsorption tower 1.

摘要： PURPOSE:To completely prevent the leakage of a liquid from a gap between the drum and the longitudinal baffle by fixing a pair of gasket guides within the drum of a heat exchanger to hermetically attach the same therein. CONSTITUTION:A pair, right and left, of gasket guides 18 are welded and fixed to the inner wall surface 22 of a drum 11 in opposition to a longitudinal baffle 12. Each gasket guide 18 is concave in cross section and loaded in its groove 19 with a gasket 20. On the other hand, to the lower surface in the vicinities of both ends of the longitudinal baffle 12 a gasket keeper 21 is fixed by welding in opposition to the groove 19. After assembling, the longitudinal baffle 12 is pressed longitudinally into the drum 11 so that the gasket keeper 21 is fitted into the groove 19. After the assembly, the gasket keeper 21 presses the gasket 20 within the groove 29 to hermetically attach the same thereto. Therefore, the leakage of a liquid from a gap 23 between the longitudinal baffle 12 and the inner wall surface 22 of the drum 11, is completely prevented.
