优化工艺参数降低苯中溶剂含量

Optimizing technological parameter reducing solvent content in benzene

针对苯抽提装置苯产品中溶剂含量偏高的问题进行了全面分析。通过对工艺参数调整,发现当原料中苯含量降低时应减少回收塔汽提水用量才能确保苯产品溶剂含量合格,并针对回收塔操作提出节能降耗建议,为同类装置的稳定运行提供指导。

The problem that the solvent was higher than design in benzene product was analysis in this paper.By using operation optimization schemes such as pressure and temperature and so on,it was found when the content of benzene in crude material decrease, the best way to low the solvent content in benzene was reducing the stripped water.Also some advices about decreasing energy cost were presented to make sure the device was operated at best status.
