Title:

CARBON DIOXIDE RECOVERY SYSTEM

Document Type and Number:

Japanese Patent JP2023103749

Kind Code:

A

Abstract:

To provide a carbon dioxide recovery system improved in heat efficiency that dissipates carbon dioxide from liquid absorbing the carbon dioxide.SOLUTION: A carbon dioxide recovery system is provided with: a distillation column that heats liquid absorbing carbon dioxide and dissipates the carbon dioxide from the liquid; a first reboiler that performs heat exchange between the liquid extracted from the distillation column and a heat medium; a methanation device including a reactor vessel that makes carbon dioxide with hydrogen to manufacture methane; a reaction gas supply line through which reaction gas flowing out from the reactor vessel is supplied as the heat medium to the first reboiler; and a reaction gas return line through which the reaction gas whose heat is exchanged with the liquid absorbing carbon dioxide in the first reboiler is returned to the methanation device.SELECTED DRAWING: Figure 1
