Title:
CARBON DIOXIDE SEPARATION/RECOVERY DEVICE, COMBUSTION SYSTEM USING SAME, THERMAL POWER GENERATION SYSTEM USING SAME, AND METHOD FOR SEPARATING AND RECOVERING CARBON DIOXIDE
Document Type and Number:
WIPO Patent Application WO/2017/126149
Kind Code:
A1
Abstract:
This carbon dioxide separation/recovery device for separating and recovering carbon dioxide from a gas to be processed, which contains nitrogen oxides and carbon dioxide, with use of a carbon dioxide scavenger is provided with a carbon dioxide trapping unit that comprises a carbon dioxide scavenger. The carbon dioxide trapping unit comprises: a gas inlet for introducing the gas to be processed; a heating unit for heating a scavenger heating gas to a predetermined temperature, said scavenger heating gas being used when carbon dioxide trapped by the carbon dioxide scavenger is separated therefrom; a cooling gas feed port for introducing a scavenger cooling gas that is used when the carbon dioxide scavenger is cooled; and a moisture mixing part for adding moisture to a nitrogen oxide separation gas that is used when nitrogen oxides are separated from the carbon dioxide scavenger. Consequently, NOx accumulated in the carbon dioxide scavenger is separated, thereby suppressing decrease in the performance of the carbon dioxide scavenger and reducing the running cost.
