摘要： A method for designing and making composite membranes having a microporous support membrane coated with a permselective layer. The method involves calculating the minimum thickness of the permselective layer such that the selectivity of the composite membrane is close to the intrinsic selectivity of the permselective layer. The invention also provides high performance membranes with optimized properties.

摘要： A method of manufacturing an integral asymmetric membrane for separating gases from each other, wherewith a membrane-former, a solvent, and/or an agent which is not a solvent for the membrane-former are mixed, are spread out or otherwise extended over a greater area, and are contacted with a precipitation agent. The integral asymmetric membrane for gas separation is particularly suitable for CO.sub.2 /CH.sub.4 separation, has improved insensitivity to water and relatively high strength and durability, and has high separation throughput and selectivity (permeability of .gtoreq.=0.1 cu m/sq m/hr/bar for CO.sub.2, and CO.sub.2 /CH.sub.4 selectivity of about 30-40), which high separation throughput and selectivity are necessary for economical separation of materials. The integral asymmetric membrane is made from a polymer, particularly polyether sulfone, as a membrane-former, is mixed with a halogenated hydrocarbon, as a solvent, as well as with a non-solvent in the form of an aliphatic alcohol, which non-solvent may possibly comprise, in addition to the aliphatic alcohol, an aliphatic carboxylic acid or an alkylbenzene.
