Patent ID: 10196574

Abstract:
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.
