Abstract: The invention provides methods and compositions for recovering oil from stillage. The method comprises the addition of a surfactant and a microparticle comprising hydrophilic silica to a grain to ethanol stillage. The methods and compositions of the present invention release oil trapped in solid aggregates, increasing the total amount of oil extracted from the stillage.

Abstract: The invention provides methods and compositions for utilizing encapsulated tracer dyes in difficult liquids such as wastewater or with highly reactive treatment chemicals such as aluminum-based coagulants. In difficult liquids or highly reactive treatment chemicals even so-called “inert” tracers end up reacting and their fluorescence changes. As a result they are inconsistent and cannot be used to measure the amount of treatment chemical present. But by encapsulating the tracer dyes, even non inert tracer dyes become inert and they can reliably be used to measure the amount of treatment chemical present even if highly reactive or in a difficult liquid.

Abstract translation: 本发明提供了在困难的液体如废水中或用高反应性处理化学品如铝基凝结剂的情况下利用封装的示踪剂染料的方法和组合物。 在困难的液体或高反应性处理化学品中，甚至所谓的“惰性”示踪剂最终会发生反应和它们的荧光变化。 因此，它们是不一致的，不能用于测量化学品存在的量。 但是通过封装示踪剂染料，即使非惰性示踪剂染料变得惰性，即使高反应性或难溶液体也能够可靠地测量化学品的存在量。
