某炼厂催化裂化装置催化剂损耗严重，检查发现了再生器旋风分离器料腿多处穿孔等故障，文章针对上述情况进行了原因分析，认为主要是料腿材质性能发生变化、拉筋的安装位置不合理等原因引起故障，“并提出了合理选材、在料腿与拉筋焊接处增殴护套等一系列改进措施，保证了装置高效、长周期稳定运行。

In the FCC unit of a refinery the catalyst lost seriously, disassembled the equipments and inspected, it was found that it had several perforations on the wall of dipleg. To solve the above problems, this article proposes failure analysis, considers the main reason is that dipleg material performance changes and installation position of the bracing is not reasonable, then put forwards a series of improvement measures, such as reasonable material selection, additional protective sleeve set in the welding place between dipleg and lacing wire. achieves the purpose of high efficiency and lone-term stable operation.
