摘要
中国石化天津分公司为进一步改善公司产品结构、拓宽高附加值产品范围,同时进一步压减柴油产量,在1.8 Mt/a加氢裂化装置上进行试生产,探讨生产5号工业白油的可行性。两次工业试生产结果表明:通过对加氢裂化装置反应部分和分馏系统的工艺参数进行针对性调整,可利用柴油生产工业白油,所得产品的倾点为-15℃和-16℃,黏度(40℃)为4.299 mm^2/s和4.415 mm^2/s,芳烃质量分数为2.95%和2.59%,满足行业标准NB/SH/T 0006—2017中5号工业白油(Ⅰ)的指标要求。
To further improve product structure,extend the range of high value-added products,and further reduce diesel output,the feasibility of producing No.5 industrial white oil in a 1.8 Mt/ a hydrocracking unit was tested.The results of two technical trial productions showed that the industrial white oil can be produced from diesel feedstock through hydrocracking by adjusting process parameters and revamping the fractionation system of the hydrocracking unit.The pour points of the products were-15℃and-16℃,the viscosities(40℃)were 4.299 mm^2 /s and 4.415 mm^2/ s,and the aromatic mass fractions were 2.95%and 2.59%,respectively,meeting the No.5 industrial white oil(Ⅰ)standard of NB /SH/ T 0006—2017.
