Solvent Extraction

  • 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.
  • 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.
  • How does hexane extraction work?
  • As the solvent (usually hexane) passes down through the bed of oil-bearing material, the oil is dissolved in the solvent and carried away. When properly carried out with stages of extraction (as will be described), the extraction process results in a very good separation of the edible oil from the solids or nutritious meal fraction. Figure 4.
  • Which oil extraction process is best?
  • This combination combines the best of each system: the pressing operation removes the higher percentages of oil which are by far the easiest to squeeze out of the solids, and the solvent extraction process is best at removing oil from about 20% down to near ½%.
