Publication number: 20180099244Abstract: 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.Type: ApplicationFiled: October 10, 2017Publication date: April 12, 2018Applicant: SEIBU GIKEN CO., LTD.Inventor: Hiroshi OKANO
