摘要： An asymmetric microporous membrane with exceptional solvent resistance and highly desirable permeability is disclosed. The membrane is made by a solution-casting or solution-spinning process from a copolyamic acid comprising the condensation reaction product in a solvent of at least three reactants selected from certain diamines and dianhydrides and post-treated to imidize and in some cases cross-link the copolyamic acid. The membrane is useful as an uncoated membrane for ultrafiltration, microfiltration, and membrane contactor applications, or may be used as a support for a permselective coating to form a composite membrane useful in gas separations, reverse osmosis, nanofiltration, pervaporation, or vapor permeation.

摘要： A process for the dehydration of a vaporous mixture. The basic process involves directing a predominantly condensable water vapor-containing vaporous mixture against the feed side of a membrane while maintaining the feed near saturation without condensing it, directing a condensable vapor sweep stream past the permeate side of the membrane in a countercurrent flow, thereby transporting water vapor in the vaporous mixture from the feed side to the permeate side of the membrane to form a noncondensed combined permeate side mixture of condensable vapor and transported water vapor.

摘要： Composite cellulosic semipermeable membranes are disclosed which are the covalently bonded reaction product of an asymmetric cellulosic semipermeable membrane and a polysiloxane containing reactive functional groups. The two reactants chemically bond by ether, ester, amide or acrylate linkages to form a siloxane-grafted cellulosic membrane having superior selectivity and flux stability. Selectivity may be enhanced by wetting the surface with a swelling agent such as water.

摘要： The process comprises delivering a spray solution comprising an active agent and a matrix material in an organic solvent to a spray-drying apparatus, atomizing the spray solution into droplets within the spray-drying apparatus to remove at least a portion of the organic solvent from the droplets to form a plurality of particles, and collecting the particles. The spray solution may be formed by forming a feed suspension comprising the active agent, the matrix material, and the organic solvent, wherein the feed suspension is at a temperature T1, and directing the feed suspension to a heat exchanger, thereby increasing the temperature of the feed suspension to a temperature T2, wherein T2 is greater than T1, and the spray solution is at a pressure greater than the vapor pressure of the organic solvent at T2, such that the active agent and matrix material are soluble in the organic solvent at T2.

摘要： The process comprises delivering a spray solution comprising at least one solute in a solvent to a spray-drying apparatus, using a flash nozzle to atomize the spray solution into droplets within the spray-drying apparatus to remove at least a portion of the solvent from the droplets to form a plurality of particles, and collecting the particles. The spray solution is directed to a heat exchanger, thereby increasing the temperature of the spray solution to a temperature T2, wherein T2 is greater than T1. The flash nozzle comprises a central tube through which the spray solution is delivered and an outer tube through which a sweep gas is delivered. The central tube may have a first outer diameter at an inlet and a second outer diameter at an outlet, wherein the first outer diameter is greater than the second outer diameter.
