芳烃抽提装置回收塔顶压力问题分析及对策

Analysis and Countermeasures of Top Pressure of Recovery Tower in Aromatics Extraction Unit

针对芳烃抽提装置在原始开工提量时回收塔顶压力高、无法达到设计参数的问题进行分析,存在塔顶与回流罐间压差高,在装置的第一周期大检修时进行技术改造后,最终解决了回收塔顶压力问题,实现了装置满负荷平稳运行。

The problem that the pressure on the top of the recovery tower was high and could not reach the design parameters in the original starting flow of the aromatics extraction unit was analyzed.There was a high pressure difference between the top of the tower and the reflux tank.After the technical transformation during the overhaul of the first cycle of the unit,the pressure problem on the top of the recovery tower was finally solved and the stable operation of the unit at full load was realized.
