What is the process of separating the different compounds in crude oil vapour?
|
Fractional Distillation
|
|
|
Describe the process of Fractional Distillation?
|
1. Crude oil is boiled.
2. Vapour & particles rise 3. As they rise they cool 4. As they reach their boiling point (determined by molecule size) they are drawn off. 5. Larger molecules have a higher boiling point |
