C_9^+重整汽油回炼催化攻克汽油干点高难题

C9+ reforming gasoline catalytic cracking to overcome the problem of high gasoline dry point

文章从延长石油集团榆林炼油厂连续重整装置通过将二甲苯塔底C_9^+馏分油至催化装置少量掺炼解决连续重整汽油干点过高问题的技术改造入手,总结了此项技改的运行情况,分析论证该改造有效降低连续重整汽油干点,确保汽油合格出厂。

In this paper,starting from the continuous reforming unit of Yulin refinery of Yanchang Petroleum Group,the technical improvement of the point of excess dry point of continuous reforming gasoline is solved by adding a small amount of C9+ distillate from the bottom of xylene tower to the catalytic unit,The operation of this technical transformation is summarized,It is proved that the transformation can effectively reduce the dry point of continuous reforming gasoline and ensure the qualified gasoline.
