Recovery of water-soluble solvents from oilseeds

Water-soluble solvents such as ethanol and isopropanol are recovered from oilseeds in equipment similar to that used for recovering hexane, but the bases for design are considerably different. Present and future commercial processes employing aqueous solvents are described, and desolventizing extracted particulates from them examined, particularly as they are affected by the concentration of alcohol in the solvent.
