WIPO Patent Application WO/2023/136065
Kind Code:
A1
Abstract:
This carbon dioxide recovery system is provided with: a distillation column for heating an absorption solution having carbon dioxide absorbed therein to cause the carbon dioxide to be released from the absorption solution; a first reboiler that causes heat exchange to occur between a heating medium and the absorption solution extracted from the distillation column; a methanation device that includes a reactor for producing methane by causing a reaction between carbon dioxide and hydrogen; a reaction gas supply line for supplying the reaction gas flowed out from the reactor, to the first reboiler, as a heating medium; and a reaction gas return line for returning, to the methanation device, the reaction gas that had exchanged heat with the absorption solution in the first reboiler.
