CFD studies on the mixing and reaction in a solution polymerization reactor for POE production
Polyolefin elastomer(POE)has excellent properties and is widely used,and its industrial production usually adopts solution polymerization method.Industrial production of POE typically involves the solution polymerization process.The rheological behavior of the POE reaction medium is highly complex and influenced by several factors,including temperature,shear rate and polymer concentration.Moreover,the rheological behavior of the reaction medium significantly impacts the mixing efficiency,thereby affecting the reaction process.Due to the interaction of reaction,rheology,and flow field,the design and production process control of POE solution polymerization reactors are facing challenges.This study establishes a computational fluid dynamics(CFD)model that integrates flow dynamics,mixing efficiency,reaction kinetics and rheological properties for POE solution polymerization reactors,based on actual measured data for kinetics and rheology.The model enables a detailed investigation of the effects of various process conditions,such as stirring speed,residence time and feed temperature on the velocity field,temperature field,concentration field and rheological properties.The findings of this study provide valuable insights and guidance for optimizing actual industrial processes.
