摘　　要：对汽柴油加氢装置分馏塔进料/反应产物换热器E-102/1、2腐蚀穿孔的原因进行了分析,采用XRD、金相分析、细菌培养试验等方法,分析了工艺、设备、设计3个方面的原因,认为停工保护与变更管理制度不完善是造成换热器腐蚀穿孔的根本原因,碱洗管理制度不完善、氯化物引起的点蚀以及微生物腐蚀等原因共同作用导致了换热器的腐蚀穿孔。The causes of corrosion and perforation of feed/reaction product heat exchanger E - 102/1,2 of fractional distillation tower of gasoline - diesel hydro- genation unit were analyzed. The reasons for three aspects of process, equipment and design are analyzed. It is considered that the shutdown shutdown and change management system are the root causes of cor- rosion and perforation of heat exchangers, the management system of caustic soda is not perfect, the pitting corrosion caused by chloride and the corrosion of microorganisms are combined The heat exchanger corrosion perforation.
