FLUID EMULSION PURIFICATION PROCESSES USING MICROPOROUS MEMBRANES HAVING FILTRATION AND ADSORPTION PROPERTIES

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 hydroph...

description 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.
