(351g) Comparison of the Technologies Utilized for Refining of the Utilized Lubricating Oil

The lubricant oil is one of the most utilized oil in any of the industry as it provides the necessary properties required for the continuous function of the machineries without wear and tear. On the similar front, once utilized, the lubricating oil leads to a huge amount of waste oil unless recovered and re-refined. Researchers continuous work for the determination of the suitable method for the refining of the utilized lubricating oil for reuse.

In the present work, the various process used for the refining of the crude oil is discussed. Primarily, the solvent extraction process proves to be an economical and effective process where the minimal utilization of the solvent lead to the tremendous efficiency in the recovery of the lubricating oil from the used oil. The comparison and effectiveness of different solvents such as Methanol, Ethanol, Iso-propanol and others are discussed.

The evaluation leads to the judgment of the utilization of the methanol as an effective and efficient solvent for the recovery of the used oil. This has been verified by the comparative studies of the properties of the fresh lubricating oil and the re-refined lubricating oil. Even the change is observed in the re-refined lubricating oil but has been an efficient outcome of the waste.
