Title:
二酸化炭素回収システムおよびその運転方法
Document Type and Number:
Japanese Patent JP7189747
Kind Code:
B2
Abstract:
To provide a carbon dioxide recovery system capable of decreasing absorption liquid components accompanied by processing object gas from which carbon dioxide is removed by an absorption tower.SOLUTION: A carbon dioxide recovery system according to an embodiment includes an absorption tower discharging absorbent absorbing carbon dioxide by contacting processing object gas including carbon dioxide with the absorbent, and absorption tower discharging gas including the processing object gas from which carbon dioxide is removed. The system includes a regeneration tower discharging the absorbent diffusing carbon dioxide by diffusing the carbon dioxide from the absorbent discharged from the absorption tower, and regeneration tower discharging gas including the carbon dioxide. And the system includes a cleaning part including an absorption tower discharging gas passage member having at least one vacancy through which the absorption tower discharging gas passes, and an injection part injecting cleaning fluid to the absorption tower discharging gas passing through the vacancy to clean the absorption tower discharging gas by use of the cleaning fluid.SELECTED DRAWING: Figure 1
