Characterization and Treatment of Straight or Branched Paraffinic Synthetic Oil by Composite Solvent Method

Abstract

The paraffinic synthetic oil i.e. lubricating oil with better performance is one of the main reasons behind proper working of industrial equipment, automobiles and domestic gadgets. It reduces friction, heat and wear between mechanical components that are in contact between each other. The prolonged use of this oil causes reduction in its own properties. During normal use impurities such as dirt, metal scrapping, water or chemicals can get mixed in the oil or be generated due to oxidation. The waste lubricating oil is one of these residues that cause water, air, soil pollution when disposed of without treatment. Re-refining is the best way to reuse the waste oil and recovering a vital resource of mineral base oil, being as good/better than original base oil. Composite solvent method is carried out for re-refining of used lubricating oil collecting from automobile service station. In this paper we study the characteristics of paraffinic synthetic oil and try to improve it.
