Abstract

Regenerated or recycle of oil is economical process and reduce the environmental pollution produce from the used lube oil. Regenerated of used oil with solvent extraction shows the yield up to 90 % which is more than the oil regenerated from the different acid. In the solvent extraction we need separate column for solvent recovery. The major benefit of solvent extraction process gives higher yield and high quality product compares with acid treatment process and also reduce the sludge generation problem that produce by acid method. That will be reduce the degree and nature of contamination, environmental/health risks associated with disposal. With help of Activated charcoal/alumina or silica gel can removes the color and various impurities presents in the recycled used oil by using different acids. The major drawback to the acid/clay method is difficulty of removal of clay sludge. MEK are 62%, 68% and 72% at feed to solvent ration 1:2, 1:4 and 1:6 settling time 24 hr., extraction 30-40 mins at temperature of 35-45 OC. As per analysis the optimum feed to solvent ration will be 1:4 in which yield of oil and its properties are satisfactory for further use of oil. As per analysis with MEK solvent regenerated oil gives highest yield or recovery of lube oil from waste oil. As per analysis the optimum feed to solvent ration will be 1:4 in which yield of oil and its properties are satisfactory for further use of oil. Solvent extraction process cost reducing, less sludge producing and high yield process. All there solvents have better yield and high recoverability by simple distillation process. By experimental analysis it’s clear that the solvent extraction process for regeneration of lube oil is easy, simple, cost effective and low sludge producing. Additionally use of alumina or silica gel are beneficial for removal of impurities and color from regenerated oil.
