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...

Beschreibung
Zusammenfassung:	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. La présente invention concerne des procédés permettant de séparer un courant d'émulsion fluide en un courant d'hydrocarbures et un courant aqueux, en mettant en contact le courant avec une membrane microporeuse pour produire un courant de produit hydrocarboné et un courant de produit aqueux. La membrane comprend une matrice polymère sensiblement hydrophobe, et une charge sensiblement hydrophile, à particules fines, sensiblement insoluble dans l'eau, répartie dans toute la matrice. La matrice polymère a une taille de pore moyenne inférieure à 1,0 micron, et les puretés des courants de produit sont indépendantes de la vitesse du courant de produit aqueux et de la taille de pore de la membrane.
