The rich liquid enters the analysis tower to realize analysis, and the analyzed carbon dioxide is sent to the carbon capture system room 3.

[0031] The carbon dioxide processing room 3 processes the carbon dioxide captured and analyzed by the carbon capture system room 1, including but not limited to liquefaction and vaporization.
