    摘要: A material is separated from a fluid mixture by contacting the mixture containing the material with a first side of essentially solid, water-insoluble, hydrophilic, semi-permeable membrane in contact with an aqueous liquid barrier having ions which combine with the material to be separated to form a water-soluble complex. The partial pressure of the material on a second side of the semi-permeable membrane is sufficiently less than the partial pressure of the material in the mixture to provide separated material on the second side of the membrane. The separated material can be removed from the vicinity of the second side of the membrane by a gas stream. The second side of the membrane is contacted with an aqueous liquid medium to reduce the loss of the aqueous liquid barrier from the membrane which may otherwise decrease in separation efficiency during use due to water losses. The gas stream used to remove the separated material may be supersaturated with the aqueous medium, e.g. water, and may contact the membrane with the aqueous medium via condensation. Alternatively, the aqueous medium such as water may be applied by a continuous or intermittent film, spray or mist. The process is particularly useful for separating olefins, especially ethylene.

    摘要: Semi-permeable membranes are made from polyamides, especially N-alkoxyalkyl polyamides, and water-soluble polyvinyl alcohols. The membranes are preferably formed as fibers. The membranes can be made from compositions containing the polymer components and a di(lower alkyl) sulfoxide, e.g. dimethyl sulfoxide. The membranes may contain complex-forming metal components. The membranes are useful for separating chemicals from their mixtures by techniques using an aqueous liquid barrier and complex-forming metals, e.g. for the separation of aliphatically-unsaturated hydrocarbons such as ethylene from close-boiling hydrocarbons.

    摘要: There is described the preparation of hydrophilic, semi-permeable film membranes having an increase in pores and containing complex-forming metals. The films can be formed from solutions having film-forming material and pore-forming material dissolved in a solvent. The films can be useful for separating a component, e.g. an aliphatically-unsaturated hydrocarbon, from mixtures by the combined use of liquid barrier permeation and metal complexing techniques. The liquid barrier is at least partially within the hydrophilic film membrane during use, and the barrier contains complex-forming metal ions in aqueous solution. The metal ions may be, for example, noble metal, nickel, mercurous, cuprous or other metal ions, and mixtures of these metal ions, and the aqueous solution may contain other cations. The separation of ethylene from ethane and methane is of particular interest.

    摘要: Novel gas separation film membranes are made by grafting alpha-olefinic, polymerizable monomers having hydrophilic functional groups and having, e.g., about from 2 to about 12 carbon atoms, to nylon, and forming a film from the resulting copolymers. A complex-forming metal component which is active in the presence of water is provided in the film. The invention also includes the process of separating components from gaseous mixtures using the membranes. Of particular interest is the separation of aliphatically-unsaturated hydrocarbons from mixtures, for example, the separation of ethylene from one or more of ethane, methane and hydrogen.
