C9 Crude Oil

• A mixture of different compounds • A finite resource found in rocks from dead organic material

A mixture of hydrocarbons

It is separated into fractions based on boiling point

A saturated hydrocarbon that contains as many H atoms as possible

CnH(2n + 2)

• Low boiling point • High volatility (turn to gas) • Low viscosity • Highly flammable

• Higher boiling point • Lower volatility (turn to gas) • High viscosity • Lower flammability (with a smoky flame)

fractional distillation

over millions of years from tiny plankton that were buried in mud

a molecule made up of only hydrogen and carbon

methane ethane propane butane

it tells the thickness of a liquid

how easily the hydrocarbon combusts

they release energy

the reaction will produce carbon dioxide and water

hydrocarbon molecules with a similar number of carbon atoms

• crude oil is heated to a very high temperature and fed into the fractionating column which is hot at the bottom and cool at the top • hydrocarbons rise up the column and condense when they reach their boiling point • the liquid fractions are then removed

they are removed from the bottom of the column

they do not condense and are removed from the column as gases
