| 20120009658 | Method and Systems for Enhancing Oil Recovery From Ethanol Production Byproducts - Methods and related systems efficiently and effectively recover a significant amount of valuable, useable oil from byproducts formed during a dry milling process used for producing ethanol. The method may include forming a concentrate from the byproduct and recovering oil from the concentrate. The step of forming the concentrate may comprise evaporating the byproduct using a multi-stage evaporator, as well as recovering the oil before the final stage of the evaporator. Further, the step of recovering oil from the concentrate may comprise using a centrifuge and, in particular, a disk stack centrifuge. Other aspects include related methods and subsystems for recovering oil. | 01-12-2012 |
| 20110282085 | Methods Of Processing Ethanol Byproducts And Related Subsystems - In one aspect of the invention, a method recovers oil from a concentrated byproduct, such as evaporated thin stillage formed during a dry milling process used for producing ethanol. The method includes forming a concentrate from the byproduct and recovering oil from the concentrate. The step of forming the concentrate may comprise evaporating the byproduct. Further, the step of separating the oil from the concentrate may comprise using a centrifuge and, in particular, a disk stack centrifuge. Other aspects of the invention include related methods and subsystems for recovering oil from thin stillage. | 11-17-2011 |
| 20110233233 | Method of Blending Fuels and Related System - A method and related system blend fuels and dispense a blended fuel to a vehicle at a fueling station. In one aspect, the method comprises selecting the desired proportion of at least one of the fuels available at the service station, blending that fuel with another one available, and delivering the blended fuel to the vehicle. Preferably, the first fuel is a non-renewable, petroleum based one, while the second fuel is a non-petroleum based, renewable one (such as ethanol or biodiesel). | 09-29-2011 |
| 20100224711 | METHODS FOR ENHANCED PROCESSING OF BIOMASS USING FLASH DESICCATION AND/OR MECHANICAL HYDRODYNAMIC CAVITATION - Methods are disclosed for conditioning biomass. The methods generally include flash dessicating the biomass to reduce a particle size of the biomass; mixing the biomass with a liquid carrier; and exposing the biomass and the liquid carrier to a mechanical hydrodynamic cavitation process. The methods can be employed during ethanol production from grain based feedstock. | 09-09-2010 |
| 20100028484 | METHODS FOR PRODUCING LIPIDS FROM ETHANOL PRODUCTION CO-PRODUCTS BY INTRODUCING LIPID PRODUCING MICROORGANISMS - Methods for producing a lipid rich product from a feedstock utilized in wet and dry milling processes for producing ethanol, the method include mixing a culture of lipid producing microorganisms with the feedstock, wherein the feedstock includes co-products of ethanol production and/or biomass; producing lipids within the lipid producing microorganisms; lysing the microorganisms; and isolating the lipid rich product. | 02-04-2010 |
| 20100004474 | Methods Of Processing Ethanol Byproducts And Related Subsystems - In one aspect of the invention, a method recovers oil from a concentrated byproduct, such as evaporated thin stillage formed during a dry milling process used for producing ethanol. The method includes forming a concentrate from the byproduct and recovering oil from the concentrate. The step of forming the concentrate may comprise evaporating the byproduct. Further, the step of separating the oil from the concentrate may comprise using a centrifuge and, in particular, a disk stack centrifuge. Other aspects of the invention include related methods and subsystems for recovering oil from thin stillage. | 01-07-2010 |

Other aspects of the invention include related methods and subsystems for recovering oil from thin stillage. | 10-15-2009 |
| 20090250412 | METHOD OF FREEING THE BOUND OIL PRESENT IN WHOLE STILLAGE AND THIN STILLAGE - A method is provided for recovering oil from stillage including oil resulting from a process used for producing ethanol. In one embodiment, the method includes heating the stillage to a temperature sufficient to at least partially separate, or unbind, the oil therefrom. The method further includes recovering the oil from the stillage. | 10-08-2009 |
| 20080299632 | Methods for Recovering Oil from a Fractionated Dry Milling Process - Processes for recovering oil from thin stillage produced during a fractionation-based dry milling process. The thin stillage can be heated or heated in combination with centrifuging to separate and recover oil from the thin stillage. Optionally, the thin stillage may be concentrated prior to recovering the oil. | 12-04-2008 |
