  • Does solvent composition influence mass transfer during soybean oil packed-bed extraction?
  • Ethanol-rich mixtures are more suitable to obtain high yield extraction. An experimental and numerical analysis is presented to investigate the influence of solvent composition and temperature on mass transfer during soybean oil packed-bed extraction using ethanol/isopropyl alcohol mixtures.
  • Which solvent is best for soybean oil extraction?
  • Isopropyl alcohol is also indicated as the most effective solvent for soybean oil extraction by Tuntiwiwattanapun et al. , when compared with methanol, ethanol and acetone.
  • What solvents are used to make oil-rich soybean flakes?
  • Oil-rich soybean flakes samples were provided by a local soybean oil processing industry. As solvents, ethanol 99.8% and isopropyl alcohol 99.8% were used. The packed bed temperature was kept constant by using a water bath. An overview of the packed bed characteristics and the solid matrix properties is presented in Table 2.
  • Can alcoholic solvents be used for soybean oil extraction?
  • Several studies focusing in thermodynamics aspects indicate alcoholic solvents as viable options for soybean oil extraction , , , . For example, Seth et al. mention that isopropyl alcohol resulted in higher oil recovery from soy flakes (between 1.5–4.7%) when compared with n-hexane in Soxhlet extractions.
  • Can ethanol/isopropyl alcohol be used for packed-bed soybean oil extraction?
  • In this work, we will present experimental data of packed-bed soybean oil extraction, using ethanol/isopropyl alcohol mixtures as solvent, and apply it to estimate the mass transfer coefficient and the intra-particle effective diffusion coefficient.
  • Is soybean oil soluble in solvent?
  • Since the soybean oil is completely soluble in this solvent, it is expected a high yield extraction. To reduce the solvent cost and allow longer analysis time, the flow rate was reduced to 1 m L / m i n. Figure 4 shows the average value for the extraction yield and the error bars constructed using the standard deviation.
