摘要： Various embodiments of the present invention relate to a method of drying a feed gas mixture. The method includes contacting a first side of one or more membranes with a feed gas mixture. The feed gas mixture includes at least water and a second gas component. Contacting the first side of the one or more membranes with the feed gas mixture produces a permeate gas mixture on a second side of the one or more membranes and a retentate gas mixture on the first side of the one or more membranes. The permeate gas mixture is enriched in water, and the retentate mixture is depleted in water. The one or more membranes have a H2O vapor permeability coefficient of at least about 25,000 Barrer at room temperature. Various embodiments of the present invention relate to a method of drying a material. The method includes contacting a material with the retentate gas mixture, to provide a dried material. Various embodiments also relate to membranes useful for performing the drying method, devices or machines that can perform the drying method, and materials dried by the drying method.

摘要： The present invention relates to silicone compositions that are useful for the production of membranes that are selectively permeable to at least one component of a gas mixture. The invention provides a method of forming the membrane. The invention also provides a method of separating components in a feed mixture using the membrane. The membrane includes a reaction product (e.g. cured product) of a silicone composition including an organopolysiloxane having at least two unsaturated aliphatic carbon-carbon bond-containing groups per molecule; a crosslinking agent having at least two silicon-bonded hydrogen atoms per molecule; a hydrosilylation catalyst; a polyether containing at least one unsaturated aliphatic carbon-carbon bond-containing group; and a siliceous filler.
