| ABSTRACT The treatment of the light wax distillate using conventional lube manufacturing processes as solvent extraction , solvent dewaxing, and hydrofinishing has been investigated. Laboratory batch extraction of what from the light wax distillate was carried out using N methylpyrrolidone (NMP) containing 3wt % water and the solvent/ oil ratio used was 3:1 at an extraction temperature of 50oC. The raffinate is then dewaxed using the solvent methyl ethylketone (MEK) together with toluene (60/40) at a solvent / oil ratio of 3/1 and at a dewaxing temperature of - 25oC. The hydrofinishing was carried out using a commercial Nickel-Tungsten catalyst in a high pressure autoclave . The hydrofining product shows important considering properties as the viscosity variation (V1=117), low temperature properties , (pour point=-33Cº) , volatility (flash point = 186oC) and the oxidation stability (t=32 min.) this higher quality product be used in blending thus preparing a appropriate compounded oil. | ||
