METHOD OF REFINING OIL RECOVERED FROM ETHANOL PROCESSING BYPRODUCTS

摘要

One aspect of the invention is a method of processing an oil-bearing byproduct of ethanol production. The method includes recovering oil from the byproduct and refining the recovered oil, such as to produce biodiesel. The method may further include refining the biodiesel. Preferably, the refining is completed on-site at an ethanol plant, and any impurities recovered as the result of the refining may be combined with distillers grains for disposal.
