Abstract:
1. A process for separating a heavy hydrocarbon stream, comprising: a) contacting the heavy hydrocarbon stream having a final point of at least 1100° F., with at least one porous membrane element in a membrane separation zone wherein the heavy hydrocarbon feedstream contacts a first side of the porous membrane element; b) retrieving at least one permeate product stream from a second side of the porous membrane element, wherein the permeate product stream is comprised of selective materials which pass through the porous membrane element from the first side of the porous membrane element and are retrieved in the permeate product stream from the second side of the porous membrane element; c) retrieving at least one retentate product stream from the first side of the porous membrane element; d) conducting at least a portion of the permeate product stream to a first refinery process unit selected from a fluid catalytic cracking (FCC) unit and a steam cracking unit; and e) conducting at least a portion of the retentate product stream to a second refinery process unit; wherein the CCR % Rejection based on the permeate product stream and the heavy hydrocarbon stream is at least 10%.
