METHOD FOR REGENERATING USED OILS BY DEMETALLIZATION AND DISTILLATION |
摘要 |
<p>The regeneration of spent oils by demetallization and distillation involves demetallization using an aqueous solution of a reagent containing anions forming relatively-insoluble salts with the metals. The separated oil is distilled at atmosphere pressure in the presence of alkaline hydroxides, for final distillation.</p> |
