摘　　要：脱碳塔是影响催化干气回收乙烯装置处理量的瓶颈。装置低负荷运行时脱碳塔操作平稳,而负荷升高时塔顶部分液罐中液位升高,操作不正常,净化气带胺液跑损严重。分析了脱碳塔的特殊性,结合现场操作存在问题,选用消泡型内件及填料对脱碳塔进行改造,改造后装置操作弹性增加,处理能力提高,脱碳塔胺液夹带现象明显降低,胺液补充量显著减少,经济效益显著,可为类似系统内件改造提供借鉴。Decarbonization column is the bottleneck which affecting the capacity of the catalytic dry gas ethylene recovery unit.When the unit operating in low load,the decarbonization column under steady state.However,when the operation load increase,the liquid level of the liquid separate pot will rise and the operation state gets bad.The particularity of decarbonization column is analyzed and combined with the problems encountered in actual operating situation,and the optimal modification of the internals in decarbonization column is put forward.Through selecting the defoaming internals and modifying,the flexibility of the operation and the capacity of the unit is increased.Moreover,the amine liquid consumption is decreased obviously and the economic benefit is remarkable.An important reference for the similar device is provided.
