Carbon dioxide is a condensable gas with strong polarization. Its solubility coefficient in membrane materials is relatively large, so its permeability coefficient and separation coefficient are also large. Generally, almost all membrane materials with good oxygen permeability can use oxygen-rich membranes to separate carbon dioxide, such as polydimethylsiloxane membranes, poly-4-methyl-1-pentene membranes for the separation of CO2 and N2, polyethersulfone membranes, polyimide membranes, etc. for the separation of CO2 and CH4. Carbon dioxide separation membrane devices can be used for oil extraction, natural gas refining, biogas refining, and carbon dioxide for fertilization.
