Carbon Capture and Sequestration (CCS) technology remains the only economically viable approach to the greenhouse gas problem for some time that is visible in the future. In the CCS technology, the capture cost accounts for 80% of the whole operation cost, and the regeneration energy consumption accounts for 1/2-1/3 of the energy consumption of the whole capture process, so the development of the low-energy regeneration technology becomes the key point for realizing the CCS technology.
Methods of capturing carbon dioxide include chemical absorption, physical adsorption, or membrane separation. The chemical absorption process can treat a large volume of exhaust gas with high removal efficiency even at low carbon dioxide concentrations (carbon dioxide content in combustion exhaust gas discharged from various sources ranges from 8 to 15%). Therefore, the absorption of carbon dioxide in flue gas after combustion based on chemical absorption is the mainstream carbon capture technology at present. In industry, it is common to use alkaline chemical absorption liquid to absorb carbon dioxide, such as alcohol amine, potash, ammonia water, etc. The alcohol amine absorbent has the characteristics of good absorption effect, low cost and recyclable absorbent, and becomes a common absorbent for capturing carbon dioxide gas.

In the field, a small amount of carbon dioxide capturing absorbent remained in a container is generally treated by a method of washing with tap water or medium water, the content of the carbon dioxide capturing absorbent in the waste water after washing is small, and the washing waste water is generally treated by a combustion method.
