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.
最后,利用一级薄膜蒸发和两级短程蒸馏工艺对废润滑油进行了再生回收工业应用试验,将柴油、汽油等轻油以及润滑油馏分分别蒸馏出来,而大部分胶质、沥青质、碳垢存在于残渣中,试验得到的再生润滑油符合基础油的标准,回收率达到75%,达到废润滑油再生的目的;同时再生过程中没有酸洗、碱中和等工序,不产生酸渣、二氧化硫等二次污染,是一种清洁环保的废润滑油再生工艺。

Transfer the filtrate to a tared beaker, evaporate to dryness without charring, dry at 105 for 1 hour, cool in a desiccator, and weigh: the difference between the weight of the residue and the weight obtained from a blank determination does not exceed 12.5 mg (0.25%).
将滤液转入已称重的烧杯,105°下干燥1小时,在不烧焦的前提下使其蒸发至干,在干燥器中冷却,称重。测得的残渣重量与空白测定中得到的残渣重量之差不超过12.5 mg (0.25%)。
