The ethanol is then distilled and dehydrated, then blended with about 2% denaturant (such as gasoline) to render it undrinkable. It is then ready for shipment. The stillage is sent through a centrifuge that separates the solids from the solubles. These co-products eventually become distillers grains, as well as corn distillers oil.

Ethanol is produced by fermentation and distillation. It begins with crushing the plant materials into tiny particles and grinding the starch into a fine powder. Water is then added to the finely ground powder to obtain a mash. A special enzyme called alpha amylase is incorporated in the mash to break down the starch into minute particles.

coal prices remain unchanged at $2.63 per MMBtu) the owner/operator of a coal fired ethanol plant would save $17.1 million annually. Conversely, the analysis shows that natural gas prices would have to drop by 40% from current levels (to $5.2/MMBtu) for natural gas fired ethanol plants to be competitive with coal fired ones.

An important issue is whether Treethanol is a superior alternative to more common forms of ethanol like corn based. The general consensus in an article by Hoover, F., & Abraham, J. (2009), is that most forms of cellulosic ethanol have the potential to yield higher energy outputs and be more sustainable than corn ethanol.

May 13, 2015· If ethanol plant yields per bushel of corn in 2014 had remained at 1997 levels (when ethanol made up just 1% of the total U.S. motor gasoline supply), the ethanol industry would have needed to grind an additional 343 million bushels, or 7% more corn, to produce the same volume of fuel.
