Used Oil Recycling Plant
Therefore, the establishments of the contaminant free used lube oil re-refining plants are required which will have following benefits:
- Reduce environment pollution.
- Save our aquatic life.
- Protect the underground water recourses.
- Produce much needed local fractions for local use and export.
- Create employment and more room for some academic and environmental research.
- Gives a second life to waste.
REFINING PROCESS:
Vacuum distillation process is involved in order to recover good quality light and heavy base oils. Whole process constitutes of three section i.e.,
- Dehydration section.
- Distillation section.
- Bleaching section.
The process goes like this :
Lube oil is first dehydrated in the dehydrated section where water content is totally removed and kerosene so obtained are stored in receiver. The dehydrated oil is pumped into distillation vessel where the oil is heated up & we obtain three fractions, Diesel, mixed oil and lube oil.
Due to rigorous heating, lube oil obtains darker color so in order to minimize the color and to derive the original color of the lube oil, we mix the lube oil with activated carbon and fuller’s earth (bleaching agent) in bleaching vessel.
