摘      要：Separation of refined soybean oil/n-hexane miscellas was studied using different commercial ultra- and nanofiltration membranes, with cut-oil＇s in the range of 1 to 5 kDa and salt rejection higher than 97% （MgSO4）. Commercial soybean oil and n-hexane miscellas with 1：3 and 1：1 mass ratios were permeated in a dead-end module. The effects of the feed pressure （2-25 bar） on oil and n-hexane fluxes and rejection were investigated. Oil rejection ranged from negative values to 30.8%, soybean oil flux from 28.9 to 617.8 g/m2 hl and n-hexane flux from 8.5 to 1,078.5 g m2 hl. Membrane fouling was observed at all experimental conditions studied. The membrane separation process has proven to be a promising alternative to solvent recovery in soybean oil extraction.
