Abstract: A solution including an associative polymer, a cyclodextrin polymer, and a solvent is provided. The associative polymer is a powder in the absence of the solvent. Additionally, a method of making down an associative polymer powder to form a solution is provided. The method includes blending a mixture of the powder, a cyclodextrin polymer, and a solvent to yield the solution, wherein the powder includes particles having been dry-cut to a median particle size of from about 200 microns to about 10,000 microns. Additionally, a powder product is provided. The powder product includes from about 80 wt. % to about 99.9 wt. % associative polymer; and from about 0.1 wt. % to about 20 wt. % of a cyclodextrin polymer.

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.

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.
