摘　　要：石化装置的烯烃尾气存在无法回收的情况,利用变压吸附过程可以实现烯烃尾气的回收。为得到较高浓度的乙烯回收产品,创造更高的经济价值,应用Aspen Adsorption吸附模拟软件,对乙烷、乙烯吸附过程建模。经过实验验证,模型可以准确提供实验参考,从而减轻变压吸附过程对实验的完全依赖。面向乙烯回收的工艺过程,应用软件对工艺操作参数进行了模拟,得到了高纯度的乙烯回收产品,从机理上验证了方案的技术可行性。Tail gas with olefin is hard to be recover in petrochemical plant.Pressure swing adsorption process can attain this target.To get much benefit the process should offer higher purity olefin product.This work try to use Aspen Adsorption software simulate the PSA process.The model can provide well result compare with experiments and can reduce the totally rely on experimental tests in PSA process research.Through ethylene recover process simulation,it offers the possibility that high purity ethylene product can be received from tail gas.
