摘　　要：某炼化企业加氢装置所产的轻石脑油主要作为企业内部轻烃芳构化装置原料或外销作为乙烯装置原料,为了提高该装置轻石脑油的附加值,对轻石脑油实施了C_(5)/C_(6)精准切割,将C_(6)送至重整装置加工,优化后重整装置苯收率增加0.33百分点,同时提高轻烃芳构化装置C_(5)消化能力,减少了C_(5)外销作乙烯原料的比例,每年效益增加572万元。The light naphtha produced in a hydrogenation unit of a refining and chemical enterprise is mainly used as the feedstock for the light hydrocarbon aromatization unit or sold as the feedstock for the steam cracking unit.In order to increase the value-added of the light naphtha,the C_(5)/C_(6) of naphtha was cut precisely,and the C_(6) was sent to the catalytic reforming unit for processing.After optimization,the benzene yield of the catalytic reforming unit was increased by 0.33 percentage point.At the same time,the C_(5) processing capacity of the light hydrocarbon aromatization unit was increased,and the export proportion of C_(5) as steam cracking feedstock was reduced.The measure can increase the benefit by 5.72 million yuan per year.
