What is the name of processing crude oil called?
Refining
1 of 7
What does refining involve?
Separating crude oil into fractions
2 of 7
What is the process of separating crude oil called?
Fractional distillation
3 of 7
How are fractions separated?
On the basis of their boiling points
4 of 7
What happens to the molecules once being fed into the tower?
Molecules that have the lowest boiling points boil off first and higher boiling point molecules rise to the top of the tower
5 of 7
Describe how fractional distillation works (part 1)
Crude oil is heated and fed into tower (fractionating tower), tower is hotter at bottom + cooler at the top, F.D relies on components having different boiling points, smaller molecules stay at the top and larger molecules stay at bottom
6 of 7
Describe how fractional distillation works (part 2)
Molecules condense in trays and are tapped off as fractions
