|発明の名称||METHOD AND DEVICE OF SEPARATION, REMOVAL AND STORAGE OF CARBON DIOXIDE IN PROCESSING OBJECT GAS|
PROBLEM TO BE SOLVED: To provide a technique improving the absorption efficiency of carbon dioxide and suppressing initial cost and running cost by using an apparatus of simple constitution in the separation, removal and storage of carbon dioxide in a processing object gas.
SOLUTION: In a separation and removal method of carbon dioxide,: a sealed high concentration gas dissolving device 3 is provided with a body part 4 having a sealed container shape and a cup-shaped body 5 disposed within the body part; a gas-liquid mixture pre-mixed with a liquid and a processing object gas is supplied into the high concentration gas dissolving device 3 in a pressurized state; liquid bubbles are generated by being injected like a shower toward the bottom of the cup-shaped body 5 disposed in the high concentration gas dissolving device 3; as the result, a gas-liquid contact area is increased and the separation and removal efficiencies of carbon dioxide are improved; and then a liquid dissolved with carbon dioxide and a gas removed with carbon dioxide by dissolution are separately discharged and recovered.
