Liquid-liquid equilibria for systems composed of rice bran oil and alcohol-rich solvents: Application to extraction and deacidification of oil

► Extraction and deacidification of vegetable oils were examined when using ethanol as the solvent. ► The effects of solvent hydration and temperature on mutual solubility of the compounds were determined. ► The experimental data were correlated using the UNIQUAC model. ► The number of theoretical stages in a solid-liquid extractor depends on solvent hydration and temperature. ► Using the UNIQUAC parameters, the solvent degree-of-recovery was determined for phases downstream of the chilling process.
