Abstract: An integrated facility for the co-production of ethanol and the pretreatment of impure vegetable oils, waxes and (animal) fats is provided. A by-product from the ethanol plant, such as distillers corn oil or distillers sorghum oil, can be directly refined on site to remove contaminants such as metals, phospholipids and inorganic anions, to enable use as ready feedstocks for a renewable diesel hydrotreatment plant. The utility of the ethanol plant infrastructure can be directly harnessed to pretreat and purify a variety of impure feedstock materials. The pretreatment reduces catalytic poisoning in the reduction process at refining facilities during the synthesis of renewable diesel. By-products of the pretreatment process are recycled to various parts of the ethanol plant for incorporation into the animal feed(s) produced by the ethanol plant or incorporated into the existing wastewater treatment and disposal system within the ethanol plant.

Abstract: An immobilized enzyme fiber contactor includes a plurality of fibers disposed within a hollow conduit. The fibers have an enzyme selected from an oxidoreductase, a transferase, a hydrolase, a lyases, an isomerase, or a ligase attached thereto. The enzymes can be attached to the fibers via an anchor group and, optionally, a bifunctional crosslinker. The enzymes can be applied, stripped, and reapplied without disassembling the reactor or discarding the fibers. The immobilized enzyme fiber contractor can be used to conduct two-phase or single-phase enzymatic reactions.

Abstract: An immobilized enzyme fiber reactor includes a plurality a fibers disposed within a hollow conduit. The fibers have an enzyme, such as a phospholipase, attached thereto. The enzymes can be attached to the fibers via an anchor group and, optionally, a bifunctional crosslinker. The enzymes can be applied, stripped, and reapplied without disassembling the reactor or discarding the fibers. The immobilized enzyme fiber reactor can be used to treat oils including phospholipids, such as soybean oil, and reduce an impurity content thereof.

Abstract: This disclosure describes techniques for using a single feedstock of barley to produce a fermented product and a method for filtering a large-particles stream from a liquid stream containing small particles of a process stream using a series of mechanical separation devices to increase yield.

Abstract: This disclosure describes providing techniques to treat large-size solids obtained from a slurry or a mash in dextrin production process as can be used in an alcohol production process. This disclosure describes a process for separating a large-particles stream from a liquid stream containing small particles of a process stream using a first mechanical separation device. The process further includes adding water to the large-particles stream to create a lower-solids stream in a cook tank. In an embodiment, the process may grind the large particles from the large-particles stream. In another embodiment, the process may adjust conditions (temperature, pH, processing aids addition) of the lower-solids stream in the cook tank and incubating for a predetermined amount of time. The process further includes separating components from the lower-solids stream by using a second mechanical separation device.

Abstract: A method that includes clarifying a thin stillage product in a mechanical processor to produce a fine suspended solids stream and a clarified thin stillage is provided. The method further includes providing the thin stillage product and the clarified thin stillage, separately or in a combined stream, to one or more evaporators to produce one or more reduced suspended solids streams, each stream having a reduced amount of suspended solids and a lower viscosity as compared to process streams having a comparable total solids content but containing a higher amount of suspended solids. The method can further included further processing of one or more of the reduced suspended solids streams to produce a bio-oil product.

Abstract: This disclosure describes techniques to optimize dewatering process in a production facility. A process separates components in a mixture by using a separation device and a dewatering device. The process receives the mixture of liquids and solids, and separates out suspended solids from the mixture of liquids and solids by using the separation device, wherein a liquid with insoluble solids stream is created. The process dewaters the liquid with insoluble solids stream by using the dewatering device to produce a liquid with small particles stream and insoluble solids having particle sizes that are greater than about 20 microns to about 1000 microns.
