DESCRIPTION
Machinery and Processes -ethanol is most commonly collected from corn but can hypothetically be a product of the fermentation of any grain. - the grain is 1. collected. 2. milled down (crushed). 3. cooked (with yeast to promote enzyme growth). 4. this cooked down grain is then liquefied and solids are removed. 5. the liquefied grain is then fermented over several days. 6. the final step is distilling the alcohol to the correct level depending on its final destination as a fuel. -methanol is created through a similar process (methanol is not as commonly used in the US) 1. after fermentation has occurred the alcohol undergoes desulphurization to remove sulphur impurities and water. 2. the alcohol then is synthesised through compression which separates a mixture of about 68% methanol 31% water out. 3. the final step is distillation.
