FIELD: chemistry.
SUBSTANCE: method for separating a stream of a fluid emulsion having a continuous aqueous phase into a hydrocarbon stream and an aqueous stream in which a stream of a fluid emulsion is passed through a microporous membrane to produce a hydrocarbon product stream and an aqueous product stream, the membrane comprises substantially a hydrophobic, polymer matrix and substantially a hydrophilic, finely divided, fine-grained, essentially water-insoluble filler distributed throughout the matrix. The polymer matrix has an average pore size of less than 1.0 micron, and the purity of the product streams is independent of the stream rate of the aqueous product and the pore size of the membrane.
EFFECT: improving the efficiency of oil separation from water in real time.
