Effect of the corn breaking method on oil distribution between stillage phases of dry-grind corn ethanol production.
The majority of fuel ethanol in the United States is produced by using the dry-grind corn ethanol process. The corn oil that is contained in the coproduct, distillers' dried grains with solubles (DDGS), can be recovered for use as a biodiesel feedstock. Oil removal will also improve the feed quality of DDGS. The most economical way to remove oil is considered to be at the centrifugation step fo...
متن کاملAnaerobic digestion of whole stillage from dry-grind corn ethanol plant under mesophilic and thermophilic conditions.
Anaerobic digestion of whole stillage from a dry-grind corn-based ethanol plant was evaluated by batch and continuous-flow digesters under thermophilic and mesophilic conditions. At whole corn stillage concentrations of 6348 to 50,786 mg total chemical oxygen demand (TCOD)/L, at standard temperature (0 °C) and pressure (1 atm), preliminary biochemical methane potential assays produced 88±8 L (4...
متن کاملComposition of corn dry-grind ethanol by-products: DDGS, wet cake, and thin stillage.
DDGS and wet distillers' grains are the major co-products of the dry grind ethanol facilities. As they are mainly used as animal feed, a typical compositional analysis of the DDGS and wet distillers' grains mainly focuses on defining the feedstock's nutritional characteristics. With an increasing demand for fuel ethanol, the DDGS and wet distillers' grains are viewed as a potential bridge feeds...
متن کاملPhosphorus flow and characterization in dry-grind corn ethanol plants.
Both the high phosphorus (P) content and P bioavailability of the animal feed coproducts of the corn-ethanol industry could potentially contribute to increased manure and soil P levels and associated environmental issues (e.g., eutrophication). Therefore, a detailed modeling of total P mass flow to the coproducts (i.e., dry distillers grains with solubles, DDGS) was performed. Distribution of P...
متن کاملFungal oil with EPA in Mucor circinelloides cultivated on thin stillage from corn-to-ethanol production
This study demonstrates the potential of the oleaginous fungus Mucor circinelloides for synthesizing oil rich in polyunsaturated fatty acids when cultivated in thin stillage (TS) and centrifuged thin stillage (CTS) from corn-to-ethanol production. Biomass yield, oil yield and its EPA content were studied at different cultivation periods and carbon to nitrogen ratios. The fungal biomass yield (g...
