METHOD FOR ABSORBING CARBON DIOXIDE GAS AND CARBON DIOXIDE GAS ABSORPTION DEVICE

Japanese Patent JP3845541

B2

PROBLEM TO BE SOLVED: To provide a carbon dioxide gas absorption device capable of continuously absorbing carbon dioxide gas with a small amount of carbon dioxide gas absorbent powder by reducing an amount of the carbon dioxide gas absorbent powder present in a regeneration step.
SOLUTION: A fluidized bed 9 of the carbon dioxide gas absorbent powder is formed in a reaction tube 1 using a fluid gas of the carbon dioxide gas and the absorption of the carbon dioxide gas is performed in this state. The carbon dioxide gas absorbent powder in the progressed state of the carbon dioxide absorption reaction is unevenly distributed at the lower part of the fluid layer. It becomes possible that only the carbon dioxide absorbent after the absorption is taken out selectively and regenerated by discharging the carbon dioxide gas absorbent from the lower part of the fluid layer and heating/regenerating at a supply source 2.
