  • Which solvent is used in soybean oil production?
  • Solvent extraction and expelling are the main processes used in soybean oil production. Hexane is currently the leading solvent in extraction , . This solvent has a high solubility for oil extraction, availability, low price, low boiling point, and heat of vaporization .
  • Which mathematical models are applied to soybean oil extraction through immersion and percolation?
  • Another mathematical model was applied to soybean oil extraction through immersion and percolation by Pramparo et al. . Despite not presenting the equations, it is interesting to highlight that all these models have considered the external mass resistance in the form of a general boundary condition given by Eq. (13).
  • Is ethanol better than hexane for soybean oil extraction?
  • Despite the fact that soybean oil extraction with hexane is more efficient, in terms of a more concentrated miscella, the outcomes obtained in this study revealed that is possible to exhaust the raw material with ethanol, and that a high oil recovery value can be reached when a S / F = 3/1 is employed.
  • How is soybean oil extracted in a continuous and countercurrent process?
  • Extraction of soybean oil in a continuous and countercurrent process. Multistage extraction was experimentally reproduced from batch single-stage assays. The process efficiency was mainly limited by the oil solubility in the solvent. The minimum solvent mass flow and the number of ideal stages were calculated.
  • Which model is best for soybean oil extraction?
  • In a general conclusion, it can be affirmed that the empirical So and Macdonald model is the best model to describe the soybean oil extraction, followed by the mass transfer kinetic model when correctly used. The typical values for the mass transfer parameters found in the literature for soybean oil extraction are presented in Table 7. Table 7.
  • Can ethanol be used as a co-solvent for soybean oil extraction?
  • The extraction of soybean oil using ethanol mixed with biodiesel as a co-solvent was analyzed by Dagostin et al. . It was noticed that high temperatures positively affect the extraction. To use hydrated ethanol as a solvent, it was necessary to use vast amounts of biodiesel as co-solvent to reach the exact extraction yield as anhydrous.
