新市场条件下歧化装置最优运行方案

Optimal operation scheme of tatory unit under new market conditions

歧化装置于2013年底首次开工以来,装置运行平稳,催化剂各项性能指标稳定。歧化装置使用催化剂型号为TA-20HP,反应总转化率达到45.47%,C_8A选择性达到72.42%,苯和C_8A选择性达到92.74%。根据苯和对二甲苯产品市场边际效益,调整反应进料中甲苯和C_9A比例,根据汽油调和池情况调整加工负荷,实现歧化装置最佳运行。

Since the year of 2013 in which Tatory Unit originally startup, both the Unit operation and the per- forrnance of the catalyst are stable. The catslyst of the Tatory Unit is TA-20HP, the general conversion was 45.47%, the selectivity of C8A was 72.42%, and the selectivity of benzene and C8A was 92.74%. The ratio be- tween toluene and C9A in the feed and the capacity of the unit is changed according to the Market marginal benefit and Gasoline reconcile situation respectively to make Tatory Unit operation optimal.
