1发达国家废润滑油回收和利用的评价原则废润滑油的回收和利用必须满足环境友好和可应用标准。其中,污染水平和粘度指数是两个关键的指标。在欧洲,再生油主要根据氯含量来分类,这主要是由于氯化物对人体有害,废油再生工艺需要采用复杂的精制工艺。欧盟规定,废油中的氯含量不能超过50ppm。具有较高粘度指数 1 Evaluation Principles for the Recovery and Utilization of Used Lubricants in Developed Countries The recycling and utilization of used lubricants must meet the requirements of environment-friendly and applicable standards. Among them, the pollution level and viscosity index are two key indicators. In Europe, the reclaimed oil is mainly classified according to the chlorine content, which is mainly due to the harmful effects of chloride on the human body. The waste oil regeneration process requires complicated refining processes. EU regulations, the waste oil in the chlorine content can not exceed 50ppm. Has a higher viscosity index
