1. Fractional Distillation

2. Chemical vs Physical Changes
Chemical Changes
Physical Changes
Molecular structure changes
Molecules DON’T disappear they are rearranged to form a new compound
EX. Combustion
Molecular structure remains the same
Ex. Evaporation Condensation

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

10. Why is there a perpetual flame at the top of the distillation tower?

11. What types of products do we use daily that are made from crude oil?
