采用加氢裂化尾油研制生产高质量润滑油基础油及白色油

USING TAIL OIL OF HYDROCRACKING TO PRODUCE PREMIUM LUBE BASE OIL AND WHITE OIL

石油三厂采用加氢裂化未转化油经催化脱蜡工艺生产高质量润滑油基础油及白色油，替代了过去老三套润滑油生产工艺。生产的基础油具有很好的低温流动性能，且对添加剂感受性好，硫、氮含量低，饱和烃含量高，可以调合中、高档润滑油。

Taking the unconverted oil from hydrocracking to produce premium lubricating base oil and white oil by catalytic dewaxing in Refinery No.3,is substituted for the old process of lube oil.The obtained base stock has good fluidity at low temperature,nice receptivity on additives,lower sulfur/nitrogen content and higher saturated hydrocarbon content,which can be used to blend for middle & high grades lubricating oil.
