- Fractional Distillation of Crude Oil
- Crude Oil
- Non-renewable Forming very slowly from animal and plant dead matter
- Mixture of mostly alkanes
- To convert crude oil to useful products
- Heating and collecting fractions. Each fraction=hydrocarbons of similar length and properties
- Crude oil is heated in a furnace
- Liquid and vapour passes in a tower which is cooler at the top and hot at the bottom
- Vapour passes up tower via trays until reaching tray that's cool enough= condense to liquid
- Shorter chain=near top as cooler and they have low boiling points
- Tar collects at the bottom-supply often exceeds demand
- Vapour passes up tower via trays until reaching tray that's cool enough= condense to liquid
- Liquid and vapour passes in a tower which is cooler at the top and hot at the bottom
- Physical process = no covalent bonds are broken. Intermolecular forces which are broken and reformed once cool
- Crude Oil
