  • Publication number: 20180099244
    Abstract: A honeycomb rotor recovering and concentrating apparatus recovers a gas such as carbon dioxide from flue gases and the like and may be capable of utilizing low-temperature waste heat 100° C. or less. The proposed method involves sorbing carbon dioxide while vaporizing and cooling by contacting a water-insoluble carbon dioxide sorbing material (solid amines, etc.) having an acidic gas sorptive capacity with a mixed gas containing carbon dioxide in a wet state. Warm water is brought into contact with the water-insoluble carbon dioxide sorbing material sorbed with carbon dioxide to desorb high concentration of carbon dioxide. The warm water is separated from the water-insoluble carbon dioxide sorbent material desorbed from carbon dioxide. Then the apparatus is returned from the separation step to the sorption step. Thereby, it is possible to drastically increase the recovery rate and recovery concentration of acidic gas (carbon dioxide) continuously.

  • Patent number: 9908083
    Abstract: An absorption-type carbon dioxide removal/condensing apparatus is removes or condenses carbon dioxide so that the apparatus secures high recovery efficiency. The apparatus has a honeycomb rotor holding a carbon dioxide absorbent, which is divided into at least a processing zone and a reproduction zone. After anyone of reproduction air for heating and a processing air is humidified by a humidifying device, both airs are ventilated into the zones, respectively. Thereby, the apparatus can improve absorption performance and density performance. If the honeycomb rotor is further divided into at least first and second processing zones, an air to be processed is humidified by a humidifier to ventilate into the first processing zone, and then a portion or all of the processing air which passed through the first procession zone is passed through the second procession zone (second pass).
