CO2 and water vapor are formed
Released into the air (CO2 is a greenhouse gas)

9. Crude Oil Can’t be used in natural state
Taken to a refinery where it is separated into simpler mixtures
Mixture of various hydrocarbons

10. Oil Refinery

11. Refining Oil Mixture of hydrocarbons with different boiling points
Heat is applied to oil causing it to boil
Forms a vapor which rises in a metal column
Vapors condense back to liquid at different heights and temperatures (hence fractions) and collect in different containers
Fractions may be condensed further or may go on for further processing

12. Putting It All Together
