Problems solved by technology

Amine absorbents are certainly a good CO 2 Adsorb the solvent, but the amine is a toxic and harmful compound, and the subsequent analysis of CO 2 It still needs to use a certain high temperature, which again increases a lot of energy consumption
In recent years, capacitive deionization technology (CDI), which has been applied in the field of seawater desalination, has entered our field of vision. Capacitive deionization technology and other absorbents are used to capture CO in exhaust gas. 2 The temperature will no longer be too high, and the power consumed by the capacitor is also low, so the CDI captures CO 2 not a viable option

Description

technical field [0001] The invention relates to the field of carbon capture, in particular to a carbon capture system for adjusting pH based on potassium carbonate absorbent combined with capacitive deionization technology. Background technique [0002] There are many CO 2 capture process, but for CO in boiler exhaust gas 2 Capture almost always involves amine absorbents. Amine absorbent is certainly a good CO 2 Adsorbs solvents, but amines are toxic and harmful compounds, and CO will be desorbed later 2 It is necessary to use a certain high temperature, which again increases a lot of energy consumption. In recent years, capacitive deionization technology (CDI), which is applied to the field of seawater desalination, has come into our field of vision. Capacitive deionization technology is used in conjunction with other absorbents to capture CO in exhaust gas. 2 The temperature will not be too high, and the power consumed by the capacitor is also lower, so the CDI captur...
