摘　　要：中国石化北京燕山分公司Ⅱ套重油催化裂化装置近年来先后实施了多项技术改造项目,包括:余热锅炉综合节能防腐改造、反应系统应用新型组合式汽提器、再生烟气系统增设四级旋风分离器及应用新型再生烟气临界流速喷嘴系统、吸收-稳定系统增设解吸塔中间再沸器。通过实施以上技术措施,装置得以更加高效、稳定、长周期运行,年增经济效益超过3 700万元。In order to improve the economic benefits of the FCCU in Yanshan Petrochemical Company, several technical reform measures for No. 2 FCC unit processing heavy oil have been adopted. The operation changes after the reforming are discussed in detail. The technical measures include revamping the waste heat boiler（WHB） for energy saving and anti-corrosion, applying an airlift loop hybrid strip- per, installing the fourth cyclone separating device and a new type of critical flow velocity injector, and a mid-reboiler in desorption tower. These measures enable the unit to have a long-term stable running. The economic benefits can be increased by more than 37 million yuan per year.
