“…Characteristic absorption bands of the oil were also found by FT-IR, even after several washes of the membrane with n-hexane, reinforcing the hypothesis of membrane fouling by the oil. The results obtained for oil fluxes are comparable to those reported for polymeric and inorganic ultra-and nanofiltration membranes (Ribeiro et al, 2006;Carvalho et al, 2006). Moura et al (2007) tested reverse osmosis membranes (BW30 -4040, DOW) and nanofiltration (DL404 -HL4040 and C -F, Osmonics) poly (amide) (PA) membranes in the permeation of triacylglycerols and free fatty acids/ethyl esters in supercritical CO 2 .…”

-The aim of this work was the study on the separation of soybean oil/n-butane mixtures using a commercial hollow fiber ultrafiltration membrane (50 kDa). Oil/n-butane mixtures with mass ratios of 1:1 and 1:3 (wt), with the feed pressures of 5, 7 and 10 bar and transmembrane pressure of 1 bar were studied. Rejections of oil between 21 to 97.2%, oil fluxes between 0.04 and 0.98 kg/m 2 h and n-butane fluxes between 4 and 46 kg/m 2 h were observed, strongly influenced by the feed concentration. The increase in oil/n-butane mass ratio caused an increase in oil rejection and a decrease in the permeate flux of oil for most assays. The increase in the operating pressure caused an increase in oil flux and a consequent decrease in oil rejection. No degradation was observed in the membrane module during the operation with this non-aqueous feed stream, as confirmed by integrity tests.

“…Ceramic membranes, in spite of the higher initial cost, present a great potential application in the separation of solutes from non-aqueous solutions, since the interactions of the solutes and solvents with the membrane ceramic material are much smaller when compared with polymeric membranes [13][14][15]. Such characteristic increases membrane stability and, consequently, provides longer shelf life.…”

The removal of gummy or mucilaginous substances from vegetable oils, commonly known as degumming, is required for the use of crude vegetable oils as the feedstock for biodiesel production. These gums reduce the rate of transesterification reactions by deactivation of the catalyst and they hinder the separation of the glycerol phase from the biodiesel. They also cause the deposition of carbon particles within engine machinery and affect performance. To take care of these issues, gums should be separated from the oils to make the oils suitable for use as fuel. Chemical treatment, membrane separation, and biological separation processes have been reported in the literature for this purpose. In the chemical treatment process aqueous solutions of chemicals like acids, bases, ethylenediaminetetraacetic acid (EDTA), and water are used for separating gums. The membrane separation process is based on size exclusion, and polymeric, ceramic, and inorganic membranes are used to separate gums from oil. In biological degumming, phospholipase groups of enzymes are used. These enzymes hydrolyze gums into fatty acids and lipophilic substances. Enzyme degumming also enhances oil‐phase yield. This paper reviews the chemical nature of gums and presents a comprehensive critical summary of different degumming technologies, their specific features, effecting parameters, advantages and disadvantages, and industrial uses. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd.
