摘　　要：低压高密度聚乙烯(HDPE)装置稳态模拟模型可用于消除操作约束条件的瓶颈,提高产品产量与质量等。软件的应用又以具反应系统的建模最为关键。本文讨论了应用POLYMERS PLUS 软件开发HDPE 装置反应系统稳态模型的方法,包括确定系统组分、热力学参数、催化剂活性中心数目以及拟合反应动力学参数等,并对所建的模型进行了验证。The engineers can use HDPE unit steady process simulation models to eliminate the bottleneck in the unit and improve thequality and the production of HDPE product.The development of HDPE unit reactor system steady models is the key.The article ismainly about the method of developing HDPE unit reactor system steady models by using the polymer process simulation software POLY-MERS PLUS,include determination of the system components,thermodynamic parameters,number of catalyst site types by deconvolut-ing the GPC data and kinetic parameters fitting.The reactor system steady models have been verified.
