Abstract
The invention discloses a carbon dioxide capturing system and method, which are used for capturing carbon dioxide from carbon dioxide gas. The carbon dioxide capturing system comprises at least one carbon dioxide absorption tower, a stripping tower, a first flash evaporator and a compressor, wherein the carbon dioxide absorption tower is provided with an absorbent; the stripping tower is communicated with the liquid outlet of the carbon dioxide absorption tower; the first flash evaporator is communicated with the liquid outlet of the stripping tower; the compressor is communicated between thegas outlet of the first flash evaporator and the gas inlet of the stripping tower. By adopting the carbon dioxide capturing system and method, the energy loss generated in the capturing of the carbondioxide can be lowered effectively.
