摘　　要：研究了催化裂化装置(RFCC)外取热器汽产中压蒸汽盐含量问题。吉林石化公司炼油厂Ⅰ套140万t/a催化裂化装置实施外取热器汽包改造、余热炉使用新型吹灰器、加强锅炉给水质量等措施,解决反应系统外取热器汽产3.5 MPa中压蒸汽盐含量高问题,避免了大型机组蒸汽透平叶轮因积垢频繁切换清洗,实现了大机组的长周期运行,消除了生产瓶颈问题。The paper discussed salty problems and countermeasures for middle-pressure steam produced from RFCC unit＇s catalyst cooler. Through a series of measures, such as reconstructing the catalyst cooler＇s steam generator, using new type ash-blowing equipment, ensuring water quality, etc, by the reforming 1.40 ×10^6 t/a RFCC unit, we have solved production bottleneck, eliminated the high-salty problems of middle-pressure steam ,avoided high-switch of large-scale equipment and realized long-cycled running.
