摘　　要：为了解决裂解汽油加氢装置脱C_9塔分离效果差、C_B芳烃收率低的技术问题,在技术上采用了高效规整填料塔的方法。在开车过程为解决分离效果差、液泛问题,对填料塔的精馏过程中进行了工艺摸索,找出了适宜的回流比和塔釜温度。同时提出了优化操作的合理、可行性建议并在实际生产中得到应用。In order to solve the problems of bad separation effect and low C8 aromatics yield in decarburization-nine tower of pyrolysis gasoline hydrogenation unit,a high effi ciency structured packing tower is adopted.To solve the problems of bad separation effect and flooding during start -up,the rectification process of packing tower is studied, and suitable reflux ratio and tower boiler temperature are defined.At the same time,reasonable and feasible sugges- tions on operation optimization are put forward and applied in practical operation.
