Cyclmax Chlosorb技术运行及操作优化

Operation and Optimization of CCR Cyclmax Chlosorb

介绍了催化重整Cyclmax Chlosorb技术工艺原理以及工艺流程,并介绍了Cyclmax Chlosorb技术工业运用中出现的低温氯腐蚀及下料腿堵塞导致再生偏烧的问题,通过传热计算得到分离料斗内壁面温度为112.1℃,低于露点温度,导致了低温氯腐蚀。通过增加伴热和提高操作温度改善了氯腐蚀问题,并提出提高预热气温度和改进催化剂除尘的建议进一步改善分离料斗下料腿堵塞问题。

Process principle and flow of CCR cyclmax chlosorb were introduced, corrosion and block in the catalyst transfer lines appeared in the disengaging hopper during the operation, and the calculated temperature of innet wall of disengaging hopper was 112. 2 °C, lower than dew point temperature which resulted in corrosion. Corrosion was improved by means of adding heat tracing and raising the operating temperature. In order to further improve the catalyst transfer lines, raising the preheated temperature and improving catalyst dedusting was suggested.
