摘要
根据UOP连续重整第三代再生技术在兰州炼油化工总厂的应用情况 ,分析了UOP连续重整第三代再生工艺的特点 ,它改变了以往再生器内部约翰逊网的结构 ,将一段还原改为两段低纯氢还原 ,并采用了无磨损提升阀组。将部分工艺条件由高温临氢环境变为低温氮气环境。这些革新降低了对设备制造材料的要求 ,使催化剂再生过程更加充分 ,且便于操作和维护。还讨论了该再生工艺在实际生产过程中暴露出的一些问题 ,提出了改进意见。在该重整工艺中 ,使用了石油化工科学研究院开发、石油三厂生产的PS Ⅳ催化剂 ,芳烃转化率达 180 .6 % ,耐磨性好 ,持氯能力强。
According to the application situation of the third generation regeneration technology of UOP CCR in Lanzhou Petroleum Processing and Chemical Complex, the process characteristics was analyzed. In comparison with the previous design, the renovation including the internal Johnson screen structure of the regenerator was changed; single stage reduction was replaced by two stage reduction with low purity hydrogen; and wear resistance lift valve assembly was installed. Some operating conditions were also changed, which converted the high temperature environment in the presence of hydrogen to low temperature environment in the presence of nitrogen. The renovations have the advantages of reducing the requirement on equipment materials, higher regeneration efficiency of catalyst as well as easy for operation and maintenance. Some problems appeared during the process application were discussed and improved methods were proposed. PS Ⅳ catalyst developed by Research Institute of Petroleum Processing and manufactured by No. 3 Refinery of Fushun Petrochemical Company was used in the process, the aromatics conversion was 180.6%. Good wear resistance and high chlorine kept ability of the catalyst was observed.
