Presentation Transcript

  1. Fractional Distillation

  2. 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 Chemical vs Physical Changes Chemical Changes Physical Changes

  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

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

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