What do these have in common?
Crude Oil
Our Learning Objectives
recall that crude oil is a complex mixture of hydrocarbons
describe how the process of fractional distillation can be used to separate the hydrocarbons in crude oil into the fractions refinery gases, gasoline, kerosene, diesel, fuel oil and bitumen
describe the physical properties and uses of the main fractions
recall that fractional distillation of crude oil produces more long-chain and fewer short-chain hydrocarbons than required
How did it get there?
Put these sentences into the right order:
Millions of tiny animals lived in the seas The pressure and heat of the rocks turned the
dead animals into oil As the dead animals decayed they were covered
with thick layers of mud and sand (sediment) When the animals died their bodies fell to the
bottom of the sea The layers of mud slowly changed into layers of
rock
How did it get there?
Why didn’t the plant material rot away?
Why do we find oil wells under both land and sea?
Oil is a fossil fuel – remains of plants and animals that lived millions of years ago.
Non-renewable

How do we separate Crude Oil into useful parts?
How does simple distillation work?
Include the following words in your answer: Heat energy Boiling point Evaporating Condensing Fraction
Fractional distillation
Now let’s apply your knowledge – how does this work?
