环保型废油再生基础油工艺简述

An Environmental Friendly Regeneration Process of a Base Oil from Waste Oil

新的环保形势下,润滑油发展方向必须适应新的环保要求,废润滑油不经处理排放,势必造成环境污染,而废润滑油中大部分组分并未变质,可以通过精制再生。传统的废油再生工艺由于其本身技术缺陷,存在二次污染的致命缺点,文章主要阐述了新环保形势下,一种新型无污染的环保型废油再生工艺。此工艺废除了旧的废油再生工艺中硫酸、白土等污染源,利用自己独立研发的蒸馏装置、萃取溶剂及脱色砂再生工艺,保证生产安全、环保,彻底实现从蒸馏至最后产品,工作环境安全、密闭、无三废产生。生产的基础油成本低、质量好、收率高,无废水、废气、废渣三废的产生,产品质量远远超过传统的"老三套"工艺生产的Ⅰ类基础油,产品指标达到Ⅱ类基础油的指标,符合当前形势下国家的新型环保政策要求。

In the new situation of environmental protection, the development direction of lubricants must adapt to the new environmental protection requirements. Waste lubricating oils are discharged without treatment, which is bound to cause environmental pollution. However, most of the components in the spent lubricating oil don＇t go bad and can be regenerated by refining. Due to its technical defects, the traditional waste oil recycling process has fatal defects of the secondary pollu- tion. In this paper, under new environmental protection situation, a new type of pollution free environmental friendly waste oil regeneration process is described. Pollution sources of sulfuric acid, clay and so on in the old waste oil recycling process are abolished, and the independently developed distillation unit, extraction solvent and decolorization sand regeneration process are utilized to ensure the production safety and environmental protection. From the distillation to the final product, the working environment is safe and airtight, and no three wastes are produced. The produced base oil has the advantages of low cost, good quality and high yield without waste water, waste gas and waste residue. The product quality is far more than that of group I base oil produced with the traditional ＂three sets＂ process, and product indicators meet the requirements of group Ⅱ base oil according with the country＇s new environmental policy requirements under the current situation.
