Week 10 – Jss 2 Third Term Basic Science Lesson Notes

WEEK 10: CRUDE OIL AND PETROCHEMICALS

 USES OF PETROCHEMICALS
Petrochemicals are used as raw materials for industrial production of essential materials such as:

1. Raw materials for the production of polymers (plastics), paints, synthetic rubber and textiles.
2. Food additives
3. Cosmetics
4. Pesticides
5. Fertilizers.

   IMPORTANCE OF CRUDE OIL AND PETROCHEMICALS.
   

   1. SOURCE OF INCOME: it serves as a major source of income in Nigeria and other oil exporting countries.
   2. SOURCES OF ENERGY: energy for heating and for motor vehicles can be gotten from crude oil.
   3. EMPLOYMENT OPPORTUNITIES: its exploration and exploitation (refining, distribution, marketing, exportation, etc.) create employment opportunities.
   4. RAW MATERIALS FOR INDUSTRIES: products are sources of industrial raw materials, thus making our industries functional.
