Fractional Distillation
Crude oil
complex of hydrocarbons
Carbon atoms form rings or chains
Used in fuel and feed stock for petrochemical industry
Finite resource
3 main substance
Petrol
Disel
Kerosene
made up of hydrogen and carbon
Process of fractional distillation
1) Crude oil is heated to 370 degrees and vapourised
2) The vapour pass into the column
3) Column is hot at the bottom and cold at the top
4) Vapour cool and condense at different temperatures
5) Long chain form near the bottom and short chain form at the top
Hydrocarbons
1) Natural gasses - Domestic heating and cooking
2) Petrol - Fuel for cars
3) Kerosene - Fuel for aircrafts
4) Diesel oil - Fuel for some cars and trains
5) Fuel oil - Used for large ships and powerstations
6) Bitumen - Used for roof and road surfacing
4 general trends
Number of carbon atoms increase
Boiling point increases
Phase of ignition increases
Viscosity increases
