Slide 6 - Slide

Recall the definition of crude oil or petroleum.
  • a fossil fuel formed underground over many millions of years by conditions of high pressure and temperature acting on the remains of dead sea creatures

Slide 7 - Slide

How is crude oil extracted from the source?

Slide 8 - Slide

How is crude oil extracted from the source?

Slide 9 - Slide

Before petroleum can be used, the various hydrocarbon molecules are separated by refining.
Oil refinery

Slide 10 - Slide

Recall the definition of fractional distillation.
  • a method of distillation using a fractionating column, used to separate liquids with different boiling points
