Crude Oil
^Un-refined
- Anaerobically (cut off oxygen supply) decomposed from remains of plants and animals
- Complex mixture of different hydrocarbons
- Non-renewable (finite) resource
- Used as raw material in production of fossil fuels
- Useless until separated by fractional distillation
Fractional Distillation
- Done on industrial scale in fractionating column
- Different fractions have different boiling points
-Each fraction contains molecules with similar number of carbon atoms – so similar boiling points
- HOT at the BOTTOM and COLD at the TOP
- Condenses as fractions according to boiling points
Main Fractions and Uses
Top to Bottom
1. Refinery Gases > LPG, domestic heating and cooking
2. Gasoline > petrol fuel for cars
3. Kerosene > fuel for aviation, domestic heating, oil paraffin for small heaters and lamps
4. Diesel Fuel > fuel for buses, lorries, railway engine, cars. Cracked to make more petrol
5. Fuel Oil > ships boilers and industrial heating
6. Bitumen> mixed with rock chippings…
