Abstract
Various types of commercial membranes (18) were used to separate the constituents of oils including triglycerides (TG), diglycerides (DG), monoglycerides (MG) and free fatty acids (FFA) in organic solvents. Cellulose acetate (CA) membrane in ethanol and gas separation membrane in hexane gave higher permeate fluxes, and large rejection differences between solutes. When membrane separation of the oil-ethanol mixture using CA membrane (NTR-1698) was repeated 16 times in batch mode (diafiltration mode, initial retentate weight 100g, and total permeate weight 504g), the composition (TG:DG:MG:FFA) of retentate changed from 31:28:9:32 to 65:29:2:4, respectively.
