摘　　要：为了解决装置结焦问题,中国石油广西石化公司350万t/a重油催化裂化装置采用美国UOP公司提升管出口快分系统和优混喷嘴技术对操作条件进行优化。结果表明,采取降低预热温度、反应压力、分馏塔塔底温度等措施后,大油气管线、沉降器集气室、提升管出口快分旋分器出口以及分馏油浆系统均未发生结焦。In order to solve the problem of coking, votex quick separation system and excellent mixing nozzle technology, developed by American UOP company, were adopted and operation conditions were optimized. The results showed that after decreasing preheating temperature, reaction temperature,bottom temperature of fractionating tower,the coking did not occur in the large gas line, plenum chamber of depressor,cyclone separator outlet of votex quick separation,fractionators and slurry system.
