. The diagram demonstrates how the corn is processed into ethanol fuel.
Overall, it is clear that the ethanol fuel making process has 8 stages, starting with storing corn and finishing with delivering products. In order to produce ethanol fuel, there are both physical and biological impacts on the corn.
At the first stage of the process, the corn is harvested and stored. After that, the next step is milling the corn into flour before the cooking stage. As soon as water is added and the corn is cooked for 4 hours. Then, fermenting the corn starts and this stage will complete in 48 hours.
Subsequently, the fermented compound goes through a separation stage divides which produces into 2 parts which are liquid ethanol fluid mix and the solid by-product which will be eliminated/discarded. Once the compound is digested, The liquid part is going to be refined for 5 hours for the purpose of removing impurities/contaminants. And tThe output of the purification clarifying stage is the pure ethanol. After that, the ethanol fuel is stored before being shipped and the final step is shipping to gas stationsthe market
