HYDROGEN SEPARATION REFORMED GAS TURBINE SYSTEM

PROBLEM TO BE SOLVED: To increase an exhaust heat recovering amount, and to reduce a pressure loss of a reformer. SOLUTION: This system has a compressor 12 compressing a fluid containing combustion oxygen; the reformer 1 having a reforming chamber 1a filled with a catalyst and a scavenging chamber 1b separated by a hydrogen separation membrane selectively separating hydrogen, and chemically reforming a fuel gas to generate a reformed gas; a combustor 9 allowing an inflow of the fluid compressed by the compressor 12 together with the reformed gas reformed by the reformer 1 for combustion to generate a combustion gas; and a gas turbine 13 converting the combustion gas into power. Vapor is made to flow into the scavenging chamber 1b, a mixed gas of water vapor and a fuel gas is led into the reforming chamber 1a to change the mixed gas into a hydrogen-containing gas with a gas turbine exhaust gas as a heat source, a part of hydrogen in the hydrogen-containing gas is led into the vapor flowing ...

POWER GENERATING SYSTEM

PROBLEM TO BE SOLVED: To provide a power generating plant which efficienctly and economically collect a large quantity of carbon dioxide exhausted from a thermal power plant, fuel cell generating plant, etc., without requiring special separating processings. SOLUTION: A fuel cell 51 is supplied with a fuel and oxygen, where chemical reactions take place at a specified temp. to make power generation, and the gas exhausted from the fuel cell 51 is fed to a combustor 52. The combustor 52 is supplied with a fluid which contains chiefly a compound consisting of oxygen or carbon atoms or oxygen atoms or hydrogen atoms, and this is mixed with a fluid containing the gas exhausted from the fuel cell 51, and the mixture is combusted. The fluid exhausted from the combustor 52 is fed to a separator 53, where the carbon dioxide is separated from water vapor and collected. Such a configuration permits efficient and economical collecting of only carbon dioxide, without requiring special separation devices ...

DESULFURIZER AND ELECTRIC POWER PLANT USING THE SAME

PROBLEM TO BE SOLVED: To obtain a miniaturized low cost desulfurizer free from the lowering of the temp. of a gas to be treated and to unnecessitate the circulation or the generation of a desulfurizing agent and to obtain an electric power plant using the same. SOLUTION: A desulfurizer is provided with a sulfide ion forming part 54 for forming a sulfide ion by the reaction with a sulfur compound, a sulfur compound supply part 52 for supplying a gas containing the sulfur compound to the sulfide ion forming part 54 and a sulfide compound discharge part 53 for discharging the sulfur compound produced by the reaction of the sulfide ion from the sulfide ion forming part 54. By this constitution, a sulfur portion in the gas supplied from the sulfur compound supply part 52 is concentrated and transferred to the gas passing through the sulfur compound discharge part 53 to be removed and to be efficiently recovered.

CO2 RECOVERY SYSTEM AND CO2 ABSORPTION LIQUID

PROBLEM TO BE SOLVED: To provide a CO2 recovery system in which heat energy necessary for recovering CO2 is reduced, and a CO2 absorption liquid. SOLUTION: In an embodiment, the CO2 recovery system includes an absorber, a regenerator, and a circulation tool. The absorption liquid includes an aqueous solution of an amine having an alcohol group, and dimethyl silicone oil in which a part of methyl groups is substituted by at least one group selected from among an aminoalkyl group, a carboxyl group, and a hydroxyl-containing alkyl group. The absorber makes a combustion exhaust gas of a fossil fuel contact with the absorption liquid for the absorption liquid to absorb CO2, which is contained in the combustion exhaust gas. The regenerator releases CO2 by applying thermal energy to the CO2-absorbed absorption liquid. A circulation tool circulates the absorption liquid between the absorber and the regenerator.
