ETHANOL PRODUCTION: THE DRY MILL PROCESS 2013  INTRODUCTION Ethanol fuel is gasoline mixed with grain alcohol. It is made from grains like corn, wheat and barley. Environmentalists love this fuel because it burns without producing greenhouse gases that are harmful to the environment. By mixing it with gasoline, fuel producers reduce the world's oil consumption. Ethanol fuel is added into gas in small amounts, as in E10, which is 10 parts ethanol and 90 parts gasoline; it reduces the vehicle's environmental impact and gas consumption. Blends like the E85, which has 85 parts ethanol to 15 parts gasoline, are used primarily by flex-fuel vehicles. The E10 ethanol fuel burns in any car like gas; no engine modifications are needed. Using E85, however, takes a few engine modifications to accommodate the large proportion of the ethanol fuel. It is well-known that ethanol fuel is made from corn. However, the fuel can also come from wheat, barley, potatoes or sugar cane. Ethanol can't be used for fuel because it is edible. Government regulations prohibit use of edibles for mass fuel consumption. Therefore, the purest type of ethanol is E-95, or anhydrous ethanol. It's 95 percent ethanol and 5 percent gasoline. Next is E85 and E10. Of these types of ethanol, only E10 has been approved for use in all vehicles. Both E95 and E85 require a flex-fuel engine. Of all the alternative fuels, ethanol fuel has made the biggest splash in recent news. It is a grain alcohol and gasoline blend that is already in use, fueling vehicles across the nation. Although everyone can agree that ethanol is needed to reduce the  American dependence on foreign oil. Many people aren't familiar with what ethanol really is, and the controversy behind its use.
