摘要： The present invention is directed to methods of separating a fluid emulsion stream into a hydrocarbon stream and an aqueous stream, by contacting the stream with a microporous membrane to yield a hydrocarbon product stream and an aqueous product stream. The membrane comprises a substantially hydrophobic, polymeric matrix, and substantially hydrophilic, finely divided, particulate, substantially water-insoluble filler distributed throughout the matrix. The polymeric matrix has a mean pore size less than 1.0 micron, and the purities of the product streams are independent of the flux rate of the aqueous product stream and the pore size of the membrane.

摘要： The present invention is directed to microfiltration and ultrafiltration membranes comprising a microporous material. The microporous material comprises: (a) a polyolefin matrix present in an amount of at least 2 percent by weight, (b) finely divided, particulate, substantially water-insoluble silica filler distributed throughout said matrix, said filler constituting from about 10 percent to about 90 percent by weight of said coated microporous material substrate, (c) at least 20 percent by volume of a network of interconnecting pores communicating throughout the coated microporous material, and (d) at least one coating composition applied to at least one surface of the membrane to adjust the surface energy of the membrane.
