摘要： A method of removing a polar solvent from a fluid volume contaminated with at least one polar impurity, such as a free fatty acid, is provided. The method comprises providing a fluid volume that includes at least one polar impurity dissolved in at least one solvent. The fluid volume is contacted with an expanding gas to remove the at least one solvent. The expanding gas may be dissolved into the at least one solvent in the fluid volume to form a gas-expanded solvent. The immiscibility of the polar impurities in the gas-expanded solvent enables separation of the polar impurities from the gas-expanded solvent. After separation of the polar impurities, at least one of the temperature and pressure may be reduced to separate the solvent from the expanding gas such that the clean solvent may be reused.

摘要： A method of removing a nonpolar solvent from a fluid volume that includes at least one nonpolar compound, such as a fat, an oil or a triglyceride, is provided. The method comprises contacting a fluid volume with an expanding gas to expand the nonpolar solvent and form a gas-expanded solvent. The gas-expanded solvent may have a substantially reduced density in comparison to the at least one nonpolar compound and/or a substantially reduced capacity to solubilize the nonpolar compound, causing the nonpolar compounds to separate from the gas-expanded nonpolar solvent into a separate liquid phase. The liquid phase including the at least one nonpolar compound may be separated from the gas-expanded solvent using conventional techniques. After separation of the liquid phase, at least one of the temperature and pressure may be reduced to separate the nonpolar solvent from the expanding gas such that the nonpolar solvent may be recovered and reused.
摘要翻译：提供了从包含至少一种非极性化合物（例如脂肪，油或甘油三酸酯）的流体体积中除去非极性溶剂的方法。该方法包括使流体体积与膨胀气体接触以膨胀非极性溶剂并形成气体膨胀溶剂。气体膨胀溶剂与至少一种非极性化合物相比可具有显着降低的密度和/或增加非极性化合物溶解能力的基本上降低的作用，导致非极性化合物与气体膨胀的非极性溶剂分离成单独的液体相。可以使用常规技术将包含至少一种非极性化合物的液相与气体膨胀溶剂分离。在分离液相后，可以降低至少一个温度和压力，以将非极性溶剂与膨胀气体分离，使得非极性溶剂可以回收和重复使用。
