  • What is solvent extraction?
  • Solvent extraction is the preferred method for the final separation of oil from oleaginous materials containing less than 30% oil by weight.
  • Which oilseeds are solvent-extracted?
  • The second most prevalent solvent-extracted oilseed is rapeseed and/or the varieties called Canola . Sunflower is also quite high in volume. A much lower volume or secondary use for soybean oil and rapeseed oil, gaining popularity in recent years, is as a feedstock for biodiesel fuels for diesel engines.
  • What solvents are used in oil extraction?
  • Various alcohols, isohexane, heptane, butane – many other solvents have found applications in niche markets. For the standard oil removal plant, only isohexane – an isomer with properties very close to hexane - has replaced hexane in a significant number of extraction plants.
  • How is oleaginous oil extracted?
  • For oleaginous materials with more than 30% oil by weight, such as rapeseed, sunflower, ground nuts, and copra, the material is mechanically and thermally prepared, mechanically deoiled to approximately 20% oil by weight and then sent to the solvent extraction process for oil separation.
