Abstract: Disclosed are methods and apparatuses for separating a wax product from a hydrocarbon feedstream by a) conducting a hydrocarbon feedstream to a membrane separation zone; b) retrieving at least one retentate product stream from the first side of the membrane element; c) retrieving at least one permeate product stream having a wax phase and an oil phase from a second side of the membrane element, wherein a pour point of the wax phase of the permeate product stream is higher than a pour point of the oil phase of permeate product stream; and d) separating a wax product from the wax phase of the permeate product stream.
