摘要： The separation factor with respect to a gas binary of a selectively gas permeable membrane of a fluoropolymer can be increased by fabricating the membrane from a composition of a blend of the fluoropolymer with a nonfugitive, nonpolymeric fluorinated adjuvant. The composition can be made by dissolving the adjuvant and the polymer in a suitably compatible solvent then forming the membrane from the solution for example by casting, dipping, or spraying the solution on a substrate and devolatilizing the solvent. The extent of the selectivity increase varies widely with the combination of fluoropolymer and adjuvant and largely increases in direct relation with the proportion of adjuvant in the membrane composition. Novel membranes of fluoropolymers adapted for separation of chemically aggressive gases can be made to have higher selectivity than previously available from the adjuvant free fluoropolymers
摘要翻译：相对于含氟聚合物的选择性气体渗透膜的气体二元体的分离因子可以通过从氟聚合物与非挥发性非聚合氟化佐剂的共混物的组合物制造膜来增加。组合物可以通过将佐剂和聚合物溶解在适当相容的溶剂中，然后通过例如通过浇铸，浸渍或将溶液喷涂在基材上并使溶剂脱挥发挥从溶液形成膜来制备。选择性增加的程度随氟聚合物和佐剂的组合而变化很大，并且在膜组合物中与佐剂的比例直接相关地大大增加。适用于分离化学腐蚀性气体的新型含氟聚合物膜可以具有比以前可获得的无辅助氟聚合物更高的选择性

摘要： The present invention provides a process for recovering hydrogen and carbon dioxide from a process stream utilizing a carbon dioxide separation unit and two membrane separation units. The present invention further provides a process within a hydrogen generation plant to increase recovery of hydrogen and capture equal to or greater than 80% of the carbon dioxide in the syngas stream. By using the process of the present invention, especially in terms of a hydrogen generation plant, it is possible to increase recovery of hydrogen and capture of the carbon dioxide in the syngas stream by balancing the recycle of the hydrogen rich permeate from the hydrogen membrane separation unit to the process unit and/or the water gas shift as capacity allows when a carbon dioxide separation unit, a carbon dioxide membrane separation unit and a hydrogen membrane separation unit are utilized.
