The illustration illustrates the steps and apparatus involved in the process of manufacturing ethanol from corn.
Overall, the process includes 9 steps, commencing with corn being harvested, through various processing steps culminating with final fuel being allocated to the gas station.
The process begins when workers collect corn. After that, they deliver corn to the storages. Then the corn goes through a milling machine before it is ready to be cooked with water for 4 hours.
Subsequently, the mixture undergoes a fermenting process until it is separated into liquid and solid by-product. The next step starts when researchers working in a lab purify the resulting liquid. Having been stored in barrels, the fuel is then delivered by a truck, allocated to the gas station and ready to be used.
