Abstract:Based on crude oil separately-feeding-separately-refining, the new technology which integrated high-pressure hydrogenation refining to three kinds of traditional processes was applied in SINOPEC Jinan Company. The furfural refining raw materials was broadened by blending the third side-draw VGO from imported crude oil and Shengli crude oil, so as to the quality grade of lubricating base oil was improved and HVIⅡ6 lubricating base oil and 62# paraffin were produced. Through production tracking analysis, various suitable raw materials,product control indicators and operating conditions were found, and then the lubricant processing programs were optimized and the profits per ton of crude oil were maximized.

0引言
中国石化济南分公司是一座“燃料-润滑油-化工”型炼化企业,原油加工能力650万t/a,其中常减压装置加工胜利进口原油,能力450万t/a;润滑油原料预处理装置加工临盘原油,能力200万t/a。润滑油生产采用中国石化石油科学研究院的“溶剂精制-加氢处理/加氢精制-溶剂脱蜡-白土补充精制”的工艺技术,通过临盘原油的分输分炼,生产HVIⅡ基础油。润滑油基础油的生产能力为16万t/a。
由于润滑油生产是采用不同蜡油切换加工的方式,这就要求要有足够的库容来储备待加工的蜡油,不仅占用了大量周转资金,增加了罐区能耗,还容易造成物料氧化变色,影响质量。为解决上述问题,就需要拓宽润滑油原料来源,实现蜡油直供糠醛精制装置,因此,尝试在润滑油原料预处理减三线蜡油基础上掺炼一定比例常减压的减三线蜡油生产合格的HVIⅡ6基础油的工业试验就显得十分必要。
1掺炼的过程及生产情况跟踪
润滑油原料预处理加工的临盘原油属于低硫中间石蜡基原油,而常减压装置加工的胜利进口原油属于含硫中间基原油。……
