What is petroleum?• Petroleum: A general term for all
naturally occurring hydrocarbons (hydrogen + carbon)
• Solid Hydrocarbons: Asphalt• Liquid Hydrocarbons: Crude oil • Gas Hydrocarbons: Natural Gas:
methane, butane, propane, etc.
Classification Of Petroleum
• Paraffin Base • Asphalt Or Naphthene Base• Intermediate Base
Where Does Petroleum Come From
• Petroleum comes from the ground and we transport it to refineries
Petroleum is a naturally occurring ,flammable liquid, that are found in geologic formations beneath the earth's surface.

TOWER
Distillation – separation by boiling point
Distillation of PetroleumOil is extracted from the ground as crude oil.
It is then refined in a distillation tower that is divided into a series of collecting trays at different temperature conditions.
The crude oil is boiled to produce vapour.
The vapour is allowed to diffuse up the tower to cool and condense at different temperatures (lightest compounds will have lowest boiling temps).
The different components of crude oil can therefore be separated.
