摘　　要：S Zorb技术是我国汽油超低硫质量升级中的主体技术,采用该技术加工的催化汽油超过了催化裂化汽油总产量的50%.随着装置运行时间的增加,S Zorb脱硫反应器分配盘的磨蚀问题日益凸显,对分配盘磨蚀进行研究分析已经势在必行.文章利用数值模拟对分配盘流场进行分析,通过改进现有分配元件结构,改进通道板的结构形式,减小其由于垫片密封失效产生的磨蚀风险.分析结果为今后设计和现场处理该类问题提供了依据和解决方法,是保证装置长周期运行的关键.S Zorbtechnology is the main technology for upgrading the ultra-low sulfur quality of gasoline in China and the processed catalytic gasoline by this technology exceeds 50%of the total output of FCC gasoline.With the increase of the unit's operating time,the abrasion problem of the grid plate of the S Zorb desulfurization reactor has become agrowing concern.It has become imperative to study and analyze the grid plate abrasion.In this paper,numerical simulation is adopted to analyze the flow field of the grid plate.By improving the structure of the existing distribution component structure and the structural form of the channel plate,the abrasion risk due to gasket seal failure is reduced.The analysis results provide a basis and solution for future design and on-site handling of such problems,which is crucial to ensure the long-term operation of the device.
