The diagram below shows how ethanol fuel is produced from corn. Summarise the information by selecting and reporting the main features and make comparisons where relevant.

The scheme makes possible to us to see phases of production ethanol fuel from corn. It is clear that corn needs to pass through eight stages to become the end product. Also, we can see that this process includes adding water. The corn begin its metamorphose with storing. Next steps are milling and that cooking. The duration of this process is four hours. Besides, as it was said above, this step demands water. Further stage is highly important. It lasts for 48 hours and called fermenting. At next phase, called separation we got two outcomes. The first one is solid by-product and second is liquid. As it is no need in second synthesised substance, we continue our work with liquid. Following process is purifying ethanol, lasts for five hours. And finally, the last two steps are storing and transporting fuel.
