Examination of Recycled Used Lube Oil Using Niger Delta Locally Source Material
Abstract: Present research work was conducted to demonstrate in detail the acid-clay recycling processes of used lube oil techniques and treatment. Adequate attention is given to these techniques employed in the recycling of used lube oil. A major menace today is the uncontrolled dumping and improper disposal of used lube oils, the magnitude which is conservatively estimated to be very high and therefore threatens our environmental existence. A comparative study was …
