Waste Oil Re-Refining
Technology & Process :
- ⇒ Pre-treatment of the used oil - using two natural polymers to remove carbon sludge substantially
- ⇒ High vacuum short path distillation(molecular distillation) is employed to remove 95% of the available oil
- ⇒ The distilled oil is bleached using active clay to get metals free base oil of required viscosity
- ⇒ The residue is processed for making soft asphalt, off speck fuel oil or briquetts. Hence it is a zero waste technology
