摘要
水会与三乙基铝、催化剂发生反应,导致三乙基铝饥饿和催化剂失活,严重影响装置稳定生产.针对对Hostalen工艺高密度聚乙烯(HDPE)装置工艺流程进行了介绍,分析罗列了可能导致反应器进水的潜在风险点;结合某装置出现过的案例,详细叙述了聚合反应系统催化剂失活时和活性恢复后的工艺表现,分析得出催化剂失活的原因是闪蒸罐后冷器的结冰融化后进入反应系统所致;并针对聚合系统进水情况提出了应急处理措施和预防措施.
Abstract
Water will react with triethyl aluminum and catalyst,resulting in triethyl eading to triethyl aluminum starvation and catalyst deactivation,which seriously affects the stable production of the plant.This paper introduces thetechnological process of Hostalen HDPE Plant,and analyzes and lists the potential risk points that maymay cause water ingress into the reactor.Based on the actual case of a factory,the process performance of polymerization reaction system was described in detail when the catalyst is deactivated and after the activity is restored.The analytic results show that the reason of catalyst deactivation was due to the melting of ice in the flash tank aftercooler and its entry into the reaction system.Emergency response measures and preventive measures have been proposed for the water water ingress into the polymerization system.
