    摘要: A method for separating aromatic hydrocarbons from a feed stream. The method includes flowing the feed stream through a first channel within a first wafer assembly that may contain an underflow distribution weir. Next, the feed stream is exposed to a first thin film polymer membrane. A stream permeates through the first thin film polymer membrane, and the permeate is produced from the first wafer assembly. The retentate is directed via a redistribution tube to a second wafer assembly that may contain an underflow distribution weir. This retentate is exposed to a second thin film polymer membrane. A second permeate stream is created that permeates through the second thin film polymer membrane. The second permeate stream is flown into the permeate zone and ultimately produced from the second wafer assembly. An apparatus for separating aromatic components from a feed stream is also disclosed. In the preferred embodiment, the apparatus includes a series of tandem wafer assemblies. The wafer assemblies comprise a first wafer, second wafer and third wafer. First and second membrane members are disposed within the wafer assemblies.

    摘要: A method and system for blending components obtained from a feed stock. The method includes flowing a first stream through a membrane member, with the membrane member having a first wafer assembly comprising a first thin film polymer membrane, a first permeate zone, and heat transfer means for transferring heat from the first permeate zone to the polymer membrane. The method includes exposing the first stream to the polymer membrane and providing a heated fluid to the heat transfer means in order to heat the permeate zone and the polymer membrane as the first stream is being flown through the first wafer assembly. The method further includes removing a permeate stream from the permeate zone. The permeate stream may be conducted to at least one refinery process unit for further processing. In the preferred embodiment, the feed stock is a naphtha. The system includes a wafer assembly adapted to receive the first stream, with the first wafer assembly comprising a plurality of wafers, and a first and second membrane member having a thin film polymer member. The system also includes heat transfer means for heating a permeate zone and the polymer membrane, as the first stream is being flown through the wafer assembly, and means for processing the produced permeate.
