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.本發明的各個實施方案涉及一種乾燥原料氣體混合物的方法。該方法包括使一個或多個膜的第一側與原料氣體混合物接觸。該原料氣體混合物包含至少水和第二氣體組分。使該一個或多個膜的第一側與所述原料氣體混合物接觸,在該一個或多個膜的第二側產生滲透氣體混合物,並在該一個或多個膜的第一側產生阻留物氣體混合物。該滲透氣體混合物富含水,且該阻留物混合物貧含水。該一個或多個膜在室溫具有至少約25,000 Barrer的H2O蒸氣滲透係數。本發明的各個實施方案涉及一種乾燥材料的方法。該方法包括使材料與阻留物氣體混合物接觸,以提供經乾燥的材料。各個實施方案也涉及可用於進行該乾燥方法的膜,可進行該乾燥方法的設備或機器,以及藉由該乾燥方法乾燥的材料。
