摘　　要：针对山西潞宝兴海新材料有限公司己内酰胺生产装置单体单元投产以来存在的入离交树脂已水电导偏高、苯精馏塔加热器堵塞频繁、离交树脂再生周期短的问题,组织技术人员进行技术改造。通过改造降低了入离交树脂已水的电导率,延长离交树脂及加氢催化剂的使用周期,取得了一定的经济效益和社会效益。This paper introduces the problems existing in the monomer unit of the Lactam production unit of Shanxi Lubao Xinghai New Material Co.,Ltd.since it was put into operation,such as the high conductivity of the incoming and outgoing resin,frequent blockage of the benzene rectifying tower heater,and short regeneration period of the outgoing resin,and organizes technical personnel to carry out technical transformation.The modification has reduced the conductivity of the water entering the resin,extended the service life of the resin and hydrogenation catalyst,and achieved certain economic and social benefits.
