Oil recycling

The improper disposal of waste engine oil poses significant environmental challenges causing serious pollution to the eco system and contaminating both land and groundwater. In this study the recycling/treatment of waste engine oil using different chemical method was investigated. The waste engine oil was first treated with glacial acetic acid and thereafter treated with kaolin. The treated oil was then neutralized with alcoholic potassium hydroxide and then filtered. The procedure was repeated using sulphuric acid and kaolin and glacial acetic acid with bentonite. The filtrate was characterized determining specific gravity, viscosity and flash point. The results showed that the flash point was within a range of 147°C - 177°C. viscosity with a range of 96.5 – 104.6mm2s -1 . However, all properties tested were close in value to the commercial lubricating oil
