直馏汽油与混合碳四非临氢改质技术的工业应用

四川石化南充炼油厂原有1套100 kt/a直馏汽油芳构化装置，后采用中国石化石油化工科学研究院开发的直馏汽油与混合碳四非临氢改质技术对该装置进行了扩能改造，装置处理能力提高到180 kt/a。1年多的实际运转结果表明，与原有技术相比，采用新技术后装置的产品分布更为合理，汽油产品的收率提高幅度大，副产品干气收率降低，能耗也相应降低。说明直馏汽油与混合碳四非临氢改质技术在液体收率和能耗等方面均优于装置原来采用的直馏汽油芳构化技术，是当前直馏汽油非临氢改质的首选工艺技术。

INDUSTRIAL APPLICATION OF STRAIGHT-RUN GASOLINE AND MIXED C4 FEED NON-HYDROGENATION UPGRADING TECHNOLOGY

A 100 kt/a straight-run gasoline aromatization unit of Nanchong Refinery was revamped and expanded its capacity to 180 kt/a by adopting the straight-run gasoline and mixed C4 feed non-hydrogenation upgrading technology developed by Research Institute of Petroleum Processing,SINOPEC.The data of more than one year operation show that compared with the base case,the product distributions improve,gasoline yield increases significantly,dry gas yield decreases and the energy consumption of the unit is lower,which demonstrates that this technology is better than the previous one.The straight-run gasoline and mixed C4 feed non-hydrogenation upgrading technology is a preferable technology for straight-run gasoline upgrading.
