摘　　要：基于流化床反应器内聚合反应的复杂性,导致聚乙烯聚合工艺的能耗通常较大,同时设计生产也存在一定困难。因此本文通过建立聚乙烯气相聚合的反应器模型,对聚合物特性及流动形式进行模拟,通过模型模拟来优化生产工艺,降低能耗。Due to the complexity of polymerization reactions in fluidized bed reactors,the energy consumption of polyethylene polymerization processes is usually high,and there are also certain difficulties in design and production.Therefore,this article establishes a reactor model for polyethylene gas-phase polymerization,simulates the characteristics and flow forms of the polymer,and optimizes the production process and reduces energy consumption through model simulation.
