摘要
采用SBD-Ⅷ型实沸点蒸馏仪对陕西榆林地区所产原油(简称为榆林原油)进行了实沸点蒸馏切割,并对所得不同馏分油的性质进行了综合分析和评价。结果表明:按照关键馏分特性分类法,榆林原油属于中间石蜡基原油;榆林原油15~65℃的馏分经精制后是高品质的乙烯裂解原料,65~175℃的馏分适用于催化重整原料;140~240℃的馏分经精制后可生产3^(#)喷气燃料;175~370,240~360℃的柴油馏分均可生产0^(#)车用柴油;360~400,400~450,450~500℃的馏分经脱蜡、精制后,是生产润滑油基础油的高品质原料;大于360℃和大于540℃的馏分,均可作为催化裂化装置的掺炼原料。
The true boiling point distillation and cutting of crude oil produced in Yulin area,Shaanxi Province(simply referred to as Yulin crude oil)was carried out by using the SBD-Ⅷtrue boiling point distiller,and the properties of the different distillated fractions obtained were comprehensively analyzed and evaluated.The results showed that according to the classification method by key fraction characteristics,Yulin crude oil belonged to intermediate paraffin-based crude oil.The naphtha fraction obtained from Yulin crude oil at 15-65℃was a high-quality ethylene cracking feedstock after refining,and the fraction at 65-175℃was suitable for catalytic reforming feedstock.The fraction at 140-240℃could be refined to produce 3^(#)jet fuel.The diesel fractions at 175-370,240-360℃both could be used to produce 0^(#)automotive diesel.The fractions at 360-400,400-450,and 450-500℃all were the high-quality raw materials for producing lubricant base oil after dewaxing and refining.The fractions of heavy oil above 360℃and vacuum residue above 540℃both could be used as the blending feedstocks for catalytic cracking units.
