摘　　要：焦炉煤气精制装置普遍采用干法脱萘工艺,产生富含杂质且高腐蚀性解吸气。实践证明,脱萘解吸气消耗产品气的同时,深度危害流经的管道、阀门、烧嘴、仪表导管等设备。介绍了马钢挖掘焦油洗油粗洗萘装置潜能,实现“一站式”脱萘,停役干法脱萘单元,并总结了洗油洗萘装置的使用、维护及改进方法。Coking oven gas refining system generally adopts dry naphthalene removal process,which produces high-inclusion and high corrosive desorption gas.Practice has shown that naphthalene removal desorption gas consumes product gas as well as deeply harms the pipes,valves,burners and instrument tubes it flows through.Masteel tapped the potential of tar washing oil raw naphthalene washing device,achieved one-stop naphthalene removal and shut down the dry naphthalene removal unit.The paper summarizes the use,maintenance and improvement method of the washing oil washing naphthalene device in Masteel.
