Carbon dioxide gas separation using organic-vapor-resistant membranes |
摘要 |
A process for separating carbon dioxide from a multicomponent gas mixture containing carbon dioxide and a hydrocarbon, such as natural gas or associated gas, using gas-separation membranes selective for carbon dioxide over the hydrocarbon. The membranes use a selective layer made from a polymer having repeating units of a fluorinated polymer, and demonstrate good resistance to plasticization by the organic components in the gas mixture under treatment, and good recovery after exposure to liquid aromatic hydrocarbons.
