摘　　要：乙烯装置自成功开车运行以来,高、低压脱丙烷塔系统一直存在着丁二烯聚合堵塞换热器、液泛、高压塔塔顶C_(2)组分返串等问题,严重阻碍了装置运行的稳定性。因此,本文从高、低压脱丙烷塔系统的运行状况着手,分析产生这一系列问题的原因,并提出了相应的解决办法,以保证双脱丙烷塔系统能够长期平稳运行。Since the successful start-up of the ethylene plant,there have been many problems in the high and low pressure depropanizer system,such as butadiene polymerization reactions cause blockage of heat exchanger,tower flooding,and backflow of C_(2) components at the top of the high-pressure tower,which seriously hinder the stability of the operation of the plant..Therefore,this paper analyzes the cause of the problem based on the operating conditions of the high and low pressure depropanizer system,then it proposes corresponding solutions to maintain the long-term stable operation of the system.
