Modeling and optimization of ethylene polymerisation processes

Abstract : Modeling and optimization of olefin polymerization processes based on polymerization and process characteristics provide guidance to plants and improve industrial processes. In this work, a model is proposed and its parameters determined to calculate thermodynamic and physical properties of the ethylene polymerization system. Based on industrial Zigler-Natta catalyzed multi-active sites ethylene polymerization kinetics, both steady and transient state plant-scale models are developed for industrial slurry and gas phase ethylene polymerization processes. The operating conditions of the reactors are analyzed; the grade transition and process optimization simulated
