WEEK 5 - 9
USES OF CRUDE OIL AND PETROCHEMICALS
1. PETROLEUME GASES
These gases are liberated at the top of the column at the temperature below 40⁰C. They are mainly hydrocarbons consisting of 1-4 carbon atom per molecule, example methane, ethane, propane, butane and ethene. They are used mainly as fuel for home and industries, for manufacturing products like hydrogen, carbon (IV) sulphide and ethyne.
