摘要： The present invention is directed to non-porous isocyanurate-crosslinked polyurethane membranes. These membranes are useful for the separation of aromatic hydrocarbons from non-aromatic hydrocarbons. The separation can be performed using any commonly accepted membrane separation technique, e.g. reverse osmosis, dialysis, pervaporation or perstraction but is preferably performed under pervaporation or perstraction conditions.

摘要： Thin film membranes of polyurea, polyurea-polyurethane alloy, polyurea-polyurea/urethane alloy or polyurea/urethane are prepared by deposition of a thin film of polyurea/urethane on a thick permeable support layer by the technique of preparing a suspension of the polyurea/urethane in a solvent which does not dissolve the thick permeable support layer and permitting the solvent to evaporate and/or permeate through the thick-permeable layer. The resulting composite membranes are useful for the selective separation of aromatic compounds from mixtures of aromatic and non-aromatic compounds.

摘要： Improved separation of feed streams containing multiple components is effected by means of a multi membrane staged pervaporation process wherein each membrane stage in series is run at progressively higher temperature, stronger vacuum or both than the preceding stage. This process is especially useful for separating components from wide boiling range mixtures.

摘要： Novel membranes, useful for the separation of aromatics from mixtures thereof with non-aromatics, in, for example, a naphtha feed stream, are characterized by possessing a urea index of at least about 20% but less than 100%, an aromatic carbon content of at least about 15 mole percent, a functional group density of at least about 10 per 1000 grams of polymer and a C = O/NH ratio of less than about 8.0. These highly aromatic polyurea/urethane membranes are symmetric, dense film membranes made from the corresponding polyurea/urethane copolymers by standard membrane casting techniques. The polyurea/urethane copolymers are preferably produced by reacting dihydroxy or polyhydroxy compounds, such as polyethers or polyesters having molecular weights in the range of about 500 to 5000 with aliphatic, alkylaromatic or aromatic diisocyanates or polyisocyanates and low molecular weight chain extenders, such as diamines, polyamines or amino alcohols. The membranes are useful for separating aromatics from non-aromatics in e.g., petroleum refining and chemical applications.

摘要： An anisotropic elastomeric membrane preferably made from polyurea/urethane is described. These anisotropic membranes may be made from the corresponding polymeric material by preparing the polymeric material in a good solvent containing less than 5 vol% non-solvent, producing a film of the polymer solution on a support with a maximum pore size less than 20 microns (µm), subjecting the film to conditions such that the solvent vapor pressure-time factor is 1000 mm Hg (133 kPa)-min. or less, preferably 200 mm Hg (26.5 kPa)-min or less, most preferably approaching 0 mm Hg (0 kPa)-min and quenching the membrane film in a non-solvent yielding a three-layered anisotropic membrane. The preferred anisotropic membranes made from the polyurea/urethane copolymer, useful for the separation of aromatics from mixtures thereof with non-aromatics and saturates, in, for example, a naphtha feed stream, are characterized by possessing a urea index of at least about 20% but less than 100%, an aromatic carbon content of at least about 15 mole percent, a functional group density of at least about 10 per 1000 grams of polymer and a C=O/NH ratio of less than about 8.0.
