fractional distillation of petroleum

What is fractional distillation?

• a process used to separate crude oil

• a process used to burn up fuels

• a way to make different products

• how oil is extracted from the ground

Fractional distillation separates crude oil based on the different __________ of the molecules in the mixture

• melting point

• boiling point

• freezing point

• chemical reactivity

A fraction of crude oil is made up of:

• Hydrocarbons of similar chain lengths

• Numbers

• Large hydrocarbons

• Alkenes only

What process happens at each level in the fractionating column?

• Evaporation

• Condensation

• Combustion
