Abstract
AbstractHexane losses in solvent extraction plants arise from a variety of causes. With the constantly increasing price of hexane, it has become imperative to identify the major loss areas and quantify losses in these areas. Hexane lost in meal leaving the desolventizer‐toaster (D‐T) is an obvious choice for investigation. A method has been developed for determining relatively high levels of hexane in hot meal leaving the D‐T. The method was designed to minimize the loss of solvent by cvaporation between the time of sampling and the actual measurement by gas chromatography (GC) Examination of the reults confirmed that losses of hexane as a result of inadequate stripping of the meal in the D‐T formed a very significant part (10–40%) of total hexane losses.
