Article Title: The Effect of Desludging/Adsorption Ratios on the Recovery of Low Pour Fuel Oil (LPFO) From Spent Engine Oil
by Etebu O.M.O and Josiah, P.N

Abstract:
The paper presents the effect of Desluding/adsorption ratios on the recovery of low pour fuel oil (LPFO) from spent engine oil. Two major processes, desludging and adsorption processes were used to recycle the spent engine oil. Concentrated sulfuric acid was used as the reagent to effect the desludging operation while activated clay was used as the adsorbent in the adsorption operation. The result shows that the efficiency of the recycling operation depends on the reagent ratio used (Desludging and adsorption ratios) and increases with the ratios. However, desludging ratio of 20:1 and an adsorption ratio of 10:1 gave the best recovery of 82.9%. Also the specific gravity, APL gravity, pour point, flash point and Viscosity Index of the recycled oil is lower than the fresh and the spent oil.
