Fractional Distillation
- Fossil Fuels are finite resources and are non renewable.
- Oils are Hydrocarbons (Hydrogen and Carbon
- LPG, Liquid petroleum Gas, contains Propane
and brutane. Bitimen has a high boiling point.
Used to make Tar
- The fractioning column has a temperature gradient.
Fractions contain mixtures of hydrocarbons with
similer boiling points. Fractions with low boling points
condense at the top of the column.
- Intermolecular forces must be broken as a
liquid. Heavy long chain molecules like Bitumen
have strong forces of attraction so it is hard to
separate them =High Boiling Point
- Light short chain molecules like Petrol
have weaker attractive forces and are
easily separated and have low BPT's.
- During boiling, intermolecular forces between
molecules break but the covalent bonds do
not.
- Smaller chain molecules are in higher demand than smaller
