3 Fractional Distillation Using heat to separate any mixture into its various components
4 Fractional Distillation of Crude Separates the mixture of crude oil into various hydrocarbons
5 How does it work?Crude oil is pumped in from storage vats.
6 Crude oil enters furnace and is heated. Hydrocarbons separate at various temps.
7 Fractions evaporate/condense at different boiling points based on size of hydrocarbon
8 Fractions are placed in separate containers and further refined if needed
