Abstract: In an aspect, a composition comprises an alkali-swellable copolymer that is derived from a mixture comprising 15 to 50 wt % of an ethylenically unsaturated carboxylic acid; 30 to 70 wt % of an ethylenically unsaturated C1-2 alkyl carboxylate ester; and 15 to 40 wt of a nonionic ethylenically unsaturated surfactant monomer of the Formula (A); and less than or equal to 0.15 wt of a multifunctional monomer contains greater than 1 vinyl group. The composition has a pH of greater than or equal to 6. The composition can optionally comprise a surfactant.

Abstract: The present invention relates to a process for producing a high protein feed ingredient from a whole stillage byproduct produced in a starch-containing grain dry milling process for producing a fermentation product, as well as enzyme blends used in the processes for partitioning a greater amount of protein from the whole stillage byproduct into the high protein fraction, rather than being retained in the wet cake, to produce a high protein feed ingredient.

Abstract: An open steam generator system is disclosed which comprises a substantially enclosed vessel having an opening for exhausting steam generated and an opening for draining residual water from the vessel. Within the vessel also is a heat exchange coil having a heat transfer fluid circulating through its runs. The vessel also includes an injector for spraying water onto the heating coil to form steam. The disclosed steam generator achieves tolerance for low water quality by minimizing surface areas in contact with water. In addition, the system promotes self-cleaning of heat exchange surfaces using thermal shock to dislodge scale deposits.
