The given diagram illustrates the sequence of ethanol fuel preparation from corn, highlighting various chemical, physical and mechanical processes it undergoes.
Overall, it is evident that ethanol fuel production is a linear procedure, consisting of 8 distinct stages. The initial phases are marked by the change of corn condition, before ultimately becoming a desired matter.
Initially, the corn is stored in a special facility, after which it is transported to a turbine-driven mill. There the vegetable is ground into small pieces to be consequently cooked with the use of water for four hours. The next step is characterised by a lengthy fermentation, which takes place in a cylindrical tube, as well as the aforementioned process. Thereafter, the resulting product is moved to the next cylinder, where the liquid is separated from the solid particles.
As the preparation unfolds, the fluid is transferred to another chamber to be purified for five hours, finally turning into ethanol. In the end, the fuel is put in the storage tanks, before being transported to the petrol stations.
