摘要:

针对粗苯加氢工艺中萃取精馏系统分离效果变差的现象,将原F-1浮阀塔盘升级为CJST高效塔盘。塔盘改造后,塔顶芳烃质量改善,萃取塔液位波动现象消失,保证了生产的稳定运行。

Abstract:

In view of the worse separation performance of extraction distillation column, the existing F-1 valve tray is replaced with high\|efficiency CJST tray.After the optimization, the aromatic hydrocarbon on top of the column improves in quality and extraction column liquid level fluctuation vanishes so that stable production can be guaranteed.
