The results of this study indicate that NMP extraction process could be successfully applied in re-refining of used mineral insulating oils. Addition of water as a co-solvent was found to improve the electrical and chemical properties of re-refined oil via modification of NMP solvent power and selectivity. It was established that 1% (w/w) …
