- 摘要:
- 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 strippe-rs,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.2001,2(2): 33-35 收稿日期：2000-10-10分类号：TE966作者简介：高建国,现从事施工技术管理工作,工程师.通讯地址:天津市大港区,邮编:300280
