Abstract:
1. A method for blending components obtained from a hydrocarbon stream comprising: (a) conducting the hydrocarbon stream through a membrane member, said membrane member having a first wafer assembly comprising a first thin film polymer membrane, a first permeate zone, and a first heat transfer means for transferring heat from said first permeate zone to said polymer membrane; (b) exposing the hydrocarbon stream to said polymer membrane; (c) providing a heated fluid to said heat transfer means in order to heat said permeate zone and said polymer membrane as the hydrocarbon stream is being conducted through said first wafer assembly; (d) removing a permeate stream from said permeate zone; and (e) conducting the permeate stream to at least one refinery process unit for further processing; wherein aromatic compounds are separated from the hydrocarbon stream.
