Industrial production plant having minimal emission of greenhouse gases, in particular emission of carbon dioxide, and method for the operation thereof

Abstract

The invention relates to an industrial production plant (), which comprises a first production plant (), which produces a CO-poor and H-rich exhaust gas from a carbon-containing feed material and which has an associated first exhaust-gas cleaning device () and an associated second exhaust-gas cleaning device (). 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 () also comprises a gas-processing plant (), which divides the exhaust gas into a carbon-containing, at least substantially H-free partial gas flow () and a carbon-free, H-rich partial gas flow (); comprises an apparatus () for producing a CO-rich gas flow, to which apparatus at least a part of a CO-containing exhaust-gas flow () arising in a firing apparatus () can be fed after flowing through the second exhaust-gas cleaning device (); and comprises a water electrolysis plant (), which produces hydrogen (H) and oxygen (), and a second production plant (), which produces methanol and/or secondary methanol products and which has a COline connection () to the apparatus () on one side and an Hline connection () to the gas-processing plant () and the water electrolysis plant () on the other side.
