DSO技术在催化裂化汽油加氢装置上的应用

APPLICATION OF DSO TECHNOLOGY IN FCC GASOLINE HYDROGENATION UNIT

介绍了DSO技术在中国石油云南石化有限公司1.4Mt/a汽油加氢装置上的应用情况。结果表明:在装置加工负荷为102%、催化裂化汽油硫质量分数为103μg/g、轻重汽油切割质量比为36∶64的条件下,生产的混合汽油产品硫质量分数为11.4μg/g,硫醇硫质量分数从18μg/g降至小于3μg/g,研究法辛烷值损失1.4个单位,低于设计值的1.7个单位;汽油诱导期从168min增加至505min;装置能耗为675MJ/t,低于设计值的838MJ/t。经过7个月的运行,装置运行平稳,生产的混合汽油产品作为国Ⅴ或国Ⅵ标准汽油调合产品进入全厂汽油池。

The application of DSO technology in 1.4 Mt a gasoline hydrogenation unit of Yunnan refinery was introduced.The data showed that at the conditions of feed S content of 103μg g,the processing load 102%,and mass ratio of light gasoline and heavy gasoline of 0.36∶0.64,the final gasoline product has sulfur content of 11.4μg g.Mercaptan sulfur content reduces from 18μg g to less than 3μg g.The RON loss of gasoline is 1.4,lower than the design value 1.7,the induction period increases from 168 min to 505 min.The energy consumption is 675 MJ t,less than the design value 838 MJ t.After 7 months of operation,the unit runs smoothly,the gasoline product can be used as the China standardⅤorⅥgasoline blending component.
