介绍了石油大学开发的新型快速分离装置———档板汽提式粗旋风分离器 (FSC系统 )的结构、工作原理 ,及其在中国石油前郭分公司重油催化裂化装置上的应用效果。通过安装后的标定试验及生产运行表明 ,FSC系统的投用减少了沉降器结焦 ,焦炭和干气产率分别降低 0 .13和 0 .12个百分点 ,轻质油收率提高 0 .4 4个百分点 ,经济效益显著。 This paper introduces the structure, working principle and application effect of the new rapid separation device developed by the University of Petroleum --- the baffle stripper rough cyclone (FSC system) and its application in the heavy oil catalytic cracking unit of the former Guo Branch of PetroChina. After the installation of the calibration test and production run showed that the FSC system to reduce the settler coking commissioning, coke and dry gas production rates were reduced by 0.13 and 0.12 percentage points, light oil yield increased by 0.4 4 4 A percentage point, significant economic benefits.
