1. RE-REFINING OF USED LUBRICATING OIL PRESENTED BY MUHAMMAD KASHIF

2. INTRODUCTION LUBRICATING OIL A substance used to reduce friction between moving surfaces, such as engine parts in vehicles, by providing a slippery film. RE-REFINING OF USED LUBRICATING OIL

3. USED OIL COMPOSITION WATER LEAD FUEL (Petrol+Kerosine+Diesel) ROAD DUST IRON PARTICLE

4. NEED OF RE-REFINING The need to conserve crude reserves. Minimizing unemployment through the building of used lube oil recycling plant. The elimination environment pollution source of used lubricant. IMPORTANTS AND BENEFITS OF RE-REFINING Reduce dependence on base oil imports saving foreign exchange. Prevent ground water contamination and pollution. Preserve natural resources such as coal and crude oil. Reduce sewage treatment costs. Eliminate improper burning of waste oil as fuel, which generate toxic fumes and air pollution.

5. SAFETY HEALTH AND ENVIRONMENT Important safety rules in the workplace Follow the Proper Dress Safety helmet Eye protection Protective gloves Safety shoes

6. EXPERIMENTAL PROCEDURE DISTILLATION COLUMN NEUTRALIZATION BLEACHIG PROCESS FILTRATION

7. DISTILLATION COLUMN Temperature : 350-400°C Purpose: Boiler: Type, Capacity=10ton Generate steam 6-7hr. Steam: Superheated Condenser: A ir C ooled .

8. NEUTRALIZATION Temperature: 70-90°C Chemical: H ₂SO ₄ Time: 4-5hr Purpose: D own Impurities. Exothermic reaction Mixing with Agitator

9. BLEACHING PROCESS Temperature: 225°C Chemical: China Clay 06%. Time: (1-½) hrs . Under Vacuum Mixing with Agitator

10. FILTRATION Temp. 190 °C Type: Filter Press Plate and Frame Polyester type Cloth

11. CONCLUSION Used oil is pollutant, and, by re-refining, the pollution is reduced. Hence, it should get the status of eco-friendly technology and get grants and incentives from the Minister of the Environment . Since re-refining leads to oil conservation, the concept of re-refining should be strongly supported by the Petroleum Conservation Research Association.
