Explanation
Some solvents with high water solubility for CO2, such as medium alcohol, polyethylene glycol dimethyl ether, N-2-methylpyrrolidine rigid, propylene carbonate, etc. By selectively absorbing CO2 molecules in a mixed gas through the affinity of solvent molecular functional groups, the goal of separating CO2 is achieved. The physical absorption of CO2 is carried out at low temperature and high pressure, with high absorption capacity,
