Question 7

Stages of fractional distillation

Answer 7

1. Oil is heated until it turns to gas. The gas enters a fractionating column
2. In the column theres a temp gradient (hot at bottom and gets cooler as you go up)
3. The more hydrocarbons there are the higher the boiling point is. They condense back into liquids and drain out early where as smaller hydrocarbons have a lower boiling point and drain out later on
4. You then end up with your crude oil
