Title:
GAS RECOVERY AND CONCENTRATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/012873
Kind Code:
A1
Abstract:
[Problem] To provide a thermal swing type carbon dioxide recovery and concentration device which is a honeycomb rotor recovery and concentration device for recovering carbon dioxide gas from duct gas and the like, that can recover carbon dioxide gas at as high a recovery rate as possible and concentrate to as high a concentration as possible, that can be made smaller, that can use low-temperature heat waste of 100°C or less and reduce the amount of energy for recovery and concentration, and that has high durability. [Solution] A honeycomb rotor carrying adsorption material (solid amines, and the like) particles having adsorption capacity for carbon dioxide gas is rotated in a casing divided and sealed into at least an adsorption zone and a desorption zone and is brought into contact with raw material that includes carbon dioxide in a state wherein the honeycomb in the adsorption zone is moist so as to adsorb the carbon dioxide gas while carrying out evaporative cooling of water, and then the honeycomb that has adsorbed the carbon dioxide gas is moved to the desorption zone and brought into contact with low pressure vapor so as to desorb high concentration carbon dioxide gas. Thus, it is possible to continuously recover carbon dioxide gas at a high recovery rate and high concentration.
