Solvent Extraction - AOCS Lipid Library
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.
