摘要： The invention relates to an industrial production plant (1), which comprises a first production plant (2), which produces a CO2-poor and H2-rich exhaust gas from a carbon-containing feed material and which has an associated first exhaust-gas cleaning device (3) and an associated second exhaust-gas cleaning device (14). The problem addressed by the invention is that of creating a solution by means of which a carbon capture and utilization method can be effectively and efficiently performed. This problem is solved in that the industrial production plant (1) also comprises a gas-processing plant (4), which divides the exhaust gas into a carbon-containing, at least substantially H2-free partial gas flow (6) and a carbon-free, H2-rich partial gas flow (7); comprises an apparatus (19) for producing a CO2-rich gas flow, to which apparatus at least a part of a CO2-containing exhaust-gas flow (17) arising in a firing apparatus (11) can be fed after flowing through the second exhaust-gas cleaning device (14); and comprises a water electrolysis plant (24), which produces hydrogen (H2) and oxygen (02), and a second production plant (20), which produces methanol and/or secondary methanol products and which has a CO2 line connection (21) to the apparatus (19) on one side and an H2 line connection (23) to the gas-processing plant (4) and the water electrolysis plant (24) on the other side.

摘要： A method for producing electrical energy in a combined energy generation plant which comprises an air treatment unit and a power station unit is proposed. In a first operating mode, air is liquefied to form an air liquefaction product and, in a second operating mode, an air liquefaction product is converted into a gaseous or supercritical state, in which said product is introduced into the power station unit and is used for producing electrical energy. In a third operating mode, air is condensed in the air treatment unit and used in the power station unit directly for producing electrical energy. It is envisaged that, in the first operating mode, the air is cooled to several temperature levels by two liquid coolants and the air liquefaction product is correspondingly heated. In addition, in the first operating mode, the air is condensed stepwise over several pressure levels.

摘要： The invention relates to a method for storing and recovering energy, wherein an air liquefaction product (LAIR) is formed during an energy storage period, and a fluid pressure flow (12) is formed during an energy recovery period using at least one part of the air liquefaction product (LAIR) and is expanded for operation in at least one energy recovery device (14, 17). The air liquefaction product (LAIR) is obtained as a liquid medium during the energy storage period by compressing air in an air conditioning device (3), said compression being operated while supplying energy, in particular while supplying a current (9), optionally stored in a cold state, and fed to an evaporator unit (7). The air liquefaction product (LAIR) is expanded for operation as a fluid pressure flow (12) in the at least one energy recovery device (14, 17) during the energy recovery period after a pressure increase. The aim of the invention is to provide a solution with which even existing gas and steam power plants or open gas turbines are to be equipped with an energy storage capability. This is achieved in that the fluid pressure flow (12), in particular an air flow, is expanded in a first energy recovery device (14) and conducted through a recuperator device (13), in particular a heat boiler, upstream of said first energy recovery device (14), and thermal energy which has been decoupled from a flue gas flow (23) fed to the recuperator device (13) is coupled into the fluid pressure flow (12) in said heating tank. The flue gas flow (23) is fed to the recuperator device (13) from a fuel-fired second energy recovery device (17), in particular a gas turbine.

摘要： In the case of a method for the heat treatment of erected, preferably large-area tube wall regions or tube wall segments, in particular of a diaphragm wall, of a steam generator, in particular of a power plant, in the installed state, it is sought to provide a solution which permits the use of steel types which are more problematic with regard to power plant operation with elevated steam parameters, in particular the steels T23 and T24, in the erection of steam generators. This is achieved in that the tube wall regions or tube wall segments for heat treatment are subjected, in the installed state in the steam generator, and in particular over a large area, to a stress-relief annealing process.
