摘　　要：某石化公司炼油厂600 kt/a汽油改质装置检修开工后加热炉炉管结焦严重,文中从垢样试验、原料油性质及工艺流程变化等角度,分析了造成炉管结焦的原因为二烯烃发生了聚合反应,提出了加强二烯烃监控,增设重汽油预处理设施等手段避免结焦现象出现。The coking of the heating furnace tube in the gasoline quality improvement unit of the600kt/a gasoline unit was serious after the maintenance and startup.The reason of coking was analyzed from the aspects of scale test,feedstock oil nature and process flow change,which was the polymerization reaction of dienes.The monitoring of dienes was proposed and heavy gasoline pretreatment facilities were added to avoid coking.
