Research Institution
70317 About 17% of known U.S. natural gas reserves are subquality due to a high carbon dioxide content. Membrane separation would be an attractive technology to remove this carbon dioxide if more robust membranes with higher selectivities and fluxes were available. This project will develop a new type of perfluoro membrane that has exceptionally good permeation characteristics and is resistant to plasticization and attack by higher hydrocarbons, aromatics, and other liquids. In Phase I, the carbon dioxide/methane separation characteristics of a number of perfluoro materials will be evaluated. The best material will be fabricated into composite membranes and then incorporated into bench-scale, spiral-wound modules. These modules will be tested with model gas mixtures to determine their separation performance. Commercial Applications and Other Benefits as described by the awardee: Currently, membrane separation is used in only 2-3% of the total carbon dioxide/natural gas separation market. Improved membranes would lower the cost of membrane processes and substantially increase market share.
