Abstract

Heavy crude oils which contain metal contaminants such as nickel, vanadium and iron may be separated from light hydrocarbon oils by passing a solution of the crude oil dissolved in a cycloparaffinic hydrocarbon solvent containing from about 5 to about 8 carbon atoms by passing through a polymeric membrane which is capable of maintaining its integrity in the presence of hydrocarbon compounds. The light hydrocarbon oils which possess relatively low molecular weights will be recovered as the permeate while the heavy oils which possess relatively high molecular weights as well as the metal contaminants will be recovered as the retentate.

Membrane separation of hydrocarbons using cycloparaffinic solvents

Patent Kulkarni, S; Chang, Y; Gatsis, J; ...

A process is described for the separation of a metal-containing heavy hydrocarbon oil fraction from a light hydrocarbon oil fraction which comprises dissolving a heavy hydrocarbon crude oil in a cycloparaffinic hydrocarbon solvent containing from 5 to about 8 carbon atoms to provide a solution comprised of the crude oil and the solvent, passing the resultant solution across a porous membrane which possesses pore sizes in the range of from about 5 to about 500 Angstroms. The membrane possesses a solubility parameter in which the absolute value (delta - 8.0) (cal/cm/sup 3/)/sup 1/2/ is greater than 1 and which ismore »« less

Patent Funk, Edward; Kulkarni, Sudhir; Chang, Y

Mixtures of heavy oils and light hydrocarbons may be separated by passing the mixture over a polymeric membrane which comprises a polymer capable of maintaining its integrity in the presence of hydrocarbon compounds at temperature ranging from about ambient to about 100.degree. C. and pressures ranging from about 50 to about 1000 psi. The membranes which possess pore sizes ranging from about 10 to about 500 Angstroms are cast from a solvent solution and recovered.

Membrane separation of hydrocarbons

Patent Chang, Y; Kulkarni, S; Funk, E

A process is described for the separation of a deasphalted crude oil and a light hydrocarbon solvent from a mixture thereof comprising passing the mixture across a polysulfone membrane at separation conditions whereby the light hydrocarbon solvent is recovered as the permeate and the deasphalted crude oil is recovered as the retentate. The membrane is prepared by a process wherein the polysulfone polymer is initially contacted in the form of a solution with a sulfonation agent under conditions suitable to achieve a degree of sulfonation of the polysulfone of from about 15 to about 50 percent, with the polysulfone subsequentlymore »« less
