The given diagram illustrates the process by which ethanol fuel is made from corn. Overall, there are 9 steps beginning with collecting corn and ending in transporting ethanol fuel to the market for consumers.
Initially, corn is harvested from fields and then it is stored in containers before being milled into small pieces. After that, an amount of water is added and this mixture is cooked for 4 hours. The following step is that the mixture is fermented for about 48 hours before being separated into liquid and solid as a by-product. The obtaining liquid is ethanol but it needs to be purified under the special condition for about 5 hours to remove all impurities which affect the quality of the fuel. Finally, after being stored, pure ethanol is transported to the market for people who use it as fuel for their transport such as vehicles or trains.
