Finally, two short-path distillation processes and one falling film evaporator are applied in the regeneration of waste lubricating oil. In the test, the diesel oil, gasoline and lubricating oil are distilled respectively, while the gelatinoid materials, asphaltene and carbon residue remain in the draft. The regenerative lubricating oil accords with the standards of base oil. And the recovery efficiency is up to 75 percent. The technology used in the test doesnt comprise processes like pickling and alkali neutralization, which would cause secondary pollution like acid draff and sulfur dioxide and so on. As a result of this, our technology is friendly to the environment.
