连续重整装置催化剂再生系统运行问题分析及对策

Analysis and Corresponding Solutions of Operational Problems in the Regeneration System of Continuous Catalytic Reforming Unit

催化剂再生系统是连续重整装置的重要组成部分。针对中石化洛阳分公司70万t/a连续重整装置在运行中存在低温部位氯腐蚀、再生器和反应器中心筒跑剂问题、反应器下部料腿堵塞和空料腿现象、重整反应器上部料斗提升氢后路约翰逊网堵塞问题和再生频繁热停问题,分析了这些问题产生的原因并提出具体应对措施。

The regeneration system of catalyst is an important part of the catalytic reforming unit. In this paper, the problems in the catalyst regeneration system of a 700 kt/a continuous catalytic reforming unit in Luoyang petrochemical company were introduced （such as chlorine corrosion of the low temperature part, loss of catalysts and so on）,reasons to result in the problems were analyzed, and the solutions were finally put forward.
