METHOD AND COMPLEX OF EQUIPMENT FOR PROCESSING CARBON OXIDES OBTAINED DURING PRODUCTION OF ALUMINIUM Russian patent published in 2024 - IPC C25C3/22 

Abstract RU 2817093 C2

FIELD: chemistry.

SUBSTANCE: group of inventions relates to a method of processing a stream of exhaust gases formed in an aluminium production plant by electrolytic reduction of aluminium oxide in a melt, using at least one anode from carbon-containing material, which contains carbon oxides due to reduction of aluminium oxide using carbon. Method of processing a stream of exhaust gases formed in an installation for production of aluminium by electrolytic reduction of aluminium oxide in a melt, using at least one anode of carbon-containing material, which contains carbon oxides due to reduction of aluminium oxide by carbon. At that, at least one partial flow of carbon oxides contained in the flow of exhaust gases is subjected to interaction with hydrogen or is mixed with a flow of hydrogen and supplied for further use. After cleaning and conditioning the flow of exhaust gases in the device, further in the reactor, for example, enrichment with carbon monoxide can be carried out, and thus, obtained synthesis gas can be supplied to a chemical or biotechnological plant for synthesis of valuable chemicals. Object of the invention is also a complex of equipment for processing a stream of exhaust gases, comprising an electrolysis device for production of aluminium by electrolytic reduction of aluminium oxide in a melt, at least one heat exchanger, in which at least one first partial flow of exhaust gases flow, as well as at least one device for cleaning and/or conditioning of exhaust gases flow from installation for aluminium production.

EFFECT: group of inventions makes it possible to direct carbon oxides obtained during electrolytic production of aluminium, at least partially, to economically feasible use and to direct to rational use of exhaust gases formed during production of anodes.
