Improvements in a procedure of re Refining of used Oil that contains Lubricating Oil

摘要

Method of solvent extraction for re Refining of used Lubricating Oil was fractionated into Light And Heavy fractions of LUBRICANT.The Heavy Lubricating oil is mixed with an effective amount of Tetrahydrofurfuryl alcohol to remove the impurities of Heavy Oil.Heavy Oil is separated from the alcohol containing impurities from the Oil.The fraction of light oil is mixed with an effective amount of Tetrahydrofurfuryl alcohol to separate the impurities from the Lubricating Oil Light.The oil is separated from the alcohol that contains impurities separated from the Oil.
