You should spend about 20 minutes on this task. 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 flow chart shows the steps involved in extracting

ethanol

from

corn

. There are a total of eight major steps before pure

ethanol

can be obtained, beginning with its storing and ending with transportation. The

process

involves cooking, fermentation and purifying stages, among others.

Corn

is the basic raw material in the production of

ethanol

.

Corn

is first stored and

then

milled. The milled

corn

is

cooked for four hours in water. Afterwards,the

is left to ferment,

corn

is

separated into a solid by-product,which is used for other purposes,and the remaining liquid,which travels

This
