针对催化裂化装置反应系统内提升管和沉降器的结焦问题，采用美国UOP公司的VSS旋风分离器、高效汽提、原料油喷嘴专利技术对沉降器的内系统进行技术改造。选用大型吊车进行整体吊装、安装，减小了安装组对的累计误差，缩短了施工周期，保证了施工质量。改造后的设备运行平稳，轻质油回收率提高了两个百分点。

In connection with the riser & settler coking on a catalytic cracking reaction system,the patented VSS cyclone separators, efficient strippers, crude oil nozzles etc from Brit. UOP Co. were used to reform settler. The accumulative errors were reduced during assembling with whole body lifting by using a heavy-duty hoist which shortened the working hours and guaranteed construction quality. The unit operation is smooth after reforming and there is a 2% increase of light hydrocarbons recovering rate.
