Abstract:
1. A process for producing an improved product stream, comprising: a) conducting a high molecular weight hydrocarbon feedstream with a final boiling point of at least 1100° F. to a membrane separation zone wherein the feedstream contacts a first side of at least one porous membrane element, wherein the porous membrane element has an average pore size from about 0.001 to about 2 microns; b) retrieving at least one retentate product stream from the first side of the porous membrane; and c) retrieving at least one permeate product stream from a second side of the porous membrane element; wherein the transmembrane pressure across the porous membrane element is from 1000 to about 2000 psig, the retentate product stream has a higher wt % of Conradson Carbon Residue than the hydrocarbon feedstream, and the permeate product stream has a lower wt % of Conradson Carbon Residue than the hydrocarbon feedstream.
