Title:
CARBON DIOXIDE RECOVERY SYSTEM AND CARBON DIOXIDE RECOVERY METHOD
Document Type and Number:
Japanese Patent JP2023013169
Kind Code:
A
Abstract:
To provide a carbon dioxide recovery system which can prevent amine evaporation of amines when absorbing/emitting CO2 while suppressing an amount of heat required for recovering CO2, and can prevent decrease in an amount of absorption/emission of CO2.SOLUTION: A carbon dioxide recovery system comprises: at least two structures having an adsorption plate that is composed of with an amine compound carried thereon and adsorbs/desorbs carbon dioxide, and a medium circulation pipe in which a heating medium for heating the adsorption plate or a cooling medium for cooling the same circulates; and two-route structure connection pipes which connect these structures. The structure connection pipes are piping for circulating the cooling medium or the heating medium, flow out the heating medium from one structure for absorbing carbon dioxide to one structure connection pipe, and flow the heating medium into the other structure for emitting carbon dioxide, and simultaneously, flow out the cooling medium from the other structure for emitting carbon dioxide to the other structure connection pipe, and flow the cooling medium into one structure for absorbing carbon dioxide.SELECTED DRAWING: Figure 7
