C1 Making crude oil
useful
- Fossil fuels
- Fossil fuels are finite resources
because they are no longer being
made
- Fossil fuels are being used up faster
than they are being formed they are
called a non-renewable resource
- Fractional distillation
- Crude oil is a mixture of many types of oil which are all
hydrocarbons. A hydrocarbon is made up of molecules
containing carbon and hydrogen only
- Crude oil is heated at the bottom
of a fractionating column.
- Oil that doesn't burn sinks as a
thick liquid to the bottom. this is
Bitumen.
- Other fractions containing
mixtures of hydrocarbons with
similar boiling points boil and their
gases rise up the column. The
column is cooler at the top
- Problems in extracting crude oil
- Transporting oil can cause
problems. oil slicks can damage
birds feathers and cause their deaths
- Their may be political problems related to
the extraction of crude oil.
- Cracking
- Cracking is a process that turns large
alkane molecules into smaller alkane and
alkene molecules.
- An alkene molecule has a double
bond which makes it useful for
making polymers
- Its also helps oil
manufactures match supply
with demand for products
like petrol
