Understanding Hexane Extraction of Vegetable Oils
Hexane (C6H14) is a hydrocarbon extracted from crude oil. In fact, hexane is similar to the gasoline we put in our cars; it’s just a slightly lighter molecule made of six carbon chains—compared to octane’s eight. In its pure form, hexane is a colorless solvent that evaporates easily and dissolves only slightly in water.
The process of extracting oil using hexane has two primary steps: pretreatment and extraction. Soybean Pretreatment = Soybeans are cleaned and prepared in the most suitable condition for extraction to occur. This step includes the soybeans going through cleaning, crushing, softening, flaking, and cooking machines.
Recent advances in green soybean oil extraction: A review
The application of green solvents in soybean oil extraction is reviewed. • Hansen parameters and COSMO-based models can serve as a solvent selection tool. • Direct substitution of hexane with green solvents is the most promising alternative. • Kinetic models and the thermodynamic assessment are analyzed comprehensively. •
Abstract. A minimal residual oil content in the meal coming out of the hexane extractor is a clear benefit for a crushing plant; the more oil yield the better revenue for the crusher. In a modern and efficient extraction plant, a residual oil content ≤ 0.5% for soybean meal is expected.
Green solvents and technologies for oil extraction from oilseeds
The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n -hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents. However, usage of hexane as a solvent has lead to several
In comparison, solvent extraction with hexane (the primary solvent used worldwide) will remove all but about ½% of residual oil, uses less horse power, and requires less maintenance. It is relatively efficient and reliable, and this is one reason why solvent extraction is the primary means of separating large tonnages of oil from protein meal.
Profitability Analysis of Soybean Oil Processes - PMC

- 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 .
- How to extract soybean oil?
- Soybean oil can be obtained by expelling or using an organic solvent. Although, the employment of solvent will always follow the expelling to increase lipid extraction yield .
- Can hexane be used for soybean oil extraction?
- In contrast, some advanced technologies such as enzyme-assisted, supercritical fluids, deep eutectic solvent, and ionic liquids seem less efficient than ordinary processes using hexane for soybean oil extraction. The best alternatives for replacing hexane seem to be ethanol, ethyl acetate, the terpenes, 2-MeTHF, and CPME.
- How do modern processing plants extract Soyabean oil?
- Modern processing plants extract soyabean oil by solvent liquid transfer. Soyabeans are cleaned, cracked, dehulled and conditioned into a thin flake before they enter the extractor. Extraction is by successive, countercurrent washes of hexane solvent.
