通过对某特大型RFCCU设计及运行数据剖析发现，该装置的整体设计、平面布置、各部分加工负荷配置基本正常，运行平稳。但在再生形式、再生器主体附件布置、局部环节及一些共性设计问题上还可进一步优化，如可选富氧两段快速床再生形式、调整烟气线路平面布置等。分析和探讨结果为后续改进和完善RFCCU的设计提供了参考，特别是对现运行数量极少的特别大型装置，以达到最佳设计，实现RFCCU可操性强、长周期、高液收、低能耗、低运行成本的安全运行状态。

Through analyzing the design and operation data of a super large RFCC unit,it is found that the overall design,equipment layout and processing load configuration for each section of the unit are basically normal,and the unit runs smoothly.However,the unit can be further optimized in the aspects including the regeneration method,the main attachment arrangement of the regenerator,local links and some common design problems.This analysis and discussion results provide a reference for further improvement in designing RFCC unit,especially for few existing super large units in China.It aims to achieve optimal design,in order to help RFCC unit to achieve strong operability,long cycle,high liquid income,low energy consumption,low operating cost and safe operation state.
