Abstract:Separation of refined soybean oil/n-hexane miscellas was studied using different commercial ultra-and nanofiltration membranes, with cutoffs in the range of 1 to 5 kDa and salt rejection higher than 97% (MgSO 4). 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.…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
