摘要： 暋对废机油进行预处理,除去部分水及杂质,再通过闪蒸装置进一步除水,然后通过常减压蒸馏工艺对
其进行切割。在常压蒸馏段可得到低凝点、高稳定性的轻质柴油,在减压蒸馏段结合络合精制灢碱洗灢白土精制等工
艺流程,可生产出不同种类的润滑油基础油等可利用资源,最后用各种添加剂进行调和以提升油品质量。经研究确
定了补充精制的工艺条件:添加络合剂质量分数为1.5%的酸溶剂4.5%进行酸洗;在40曟的温度下,添加质量分数
为40%的NaOH 水溶液1%进行碱洗;在小于120曟的温度下,添加白土3%搅拌25~30min。采用此工艺不仅可
以有效地减少对环境的污染,而且可极大地提高废机油的再生利用率。

Abstract: The pretreatment of spent lubricating oil to remove part of the water and impurities was carried out firstly, then the flash device are used for further removal of water, followed by the distillation in atmospheric and vacuum distillation unit. A lowfreezingpoint, high stable light diesel were produced in the atmospheric distillation zone; different kinds of lubricating base oils which are all available resources were produced by vacuum distillation segment combined with complex agent refiningalkaline cleaningclay refining process. Additives were added finally to improve the oil quality. The additional purification process conditions were identified: the mass fraction of acid solvent 4.5% which contains the mass fraction complexing agent 1.5% for pickling; 1% NaOH aqueous solution with its mass fraction of 40% were added for alkaline cleaning at 40 ℃, then 3% clay was added and stirred for 25～30 min at the temperature less than 120 ℃. This processing technology not only reduces the pollution effectively, but also greatly improves the reutilization of waste oil.
