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，它们不一致，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。

Abstract: Provided is a method of processing stillage from an ethanol production process. The method comprises treating stillage comprising oil, protein, and water upstream of a separation, concentration or evaporation step with at least one organic coagulant and at least one flocculant, thereby forming treated thin stillage comprising solids which include at least a portion of the oil and protein; and clarifying the treated stillage via a solid/liquid separation process thereby forming clarified stillage and a separated solids phase comprising at least a portion of the protein from the stillage.

Abstract: A method of detecting free flocculant polymer having a net charge present in an aqueous phase of a multi-phase substance is provided. The multi-phase substance comprises a solid phase, an organic phase, and the aqueous phase. The method comprises separating the solid phase from the multi-phase substance to form a dual phase top liquid comprising the organic phase and the aqueous phase; separating the organic phase from the dual phase top liquid, leaving the aqueous phase; combining the free flocculant polymer in the aqueous phase and a dye having an opposite net charge than that of the free flocculant polymer, thereby causing a spectroscopically observable change in the aqueous phase; and analyzing the aqueous phase via spectrometry to determine the concentration of the free flocculant polymer in the multi-phase substance.
