  • Fluid separation membranes and use thereof
    Patent number: 12673298
    Abstract: A process is disclosed for the production of highly asymmetric hollow fibers suitable for use as permselective gas separation membranes and for the fabrication of composite membranes derived from polyetherimide. The resulting polyetherimide membranes exhibit superior selectivity and permeability characteristics and are particularly advantageous for the separation of carbon dioxide from natural gas, biogas, and other gas streams containing acid gases.
