气相法聚丙烯装置主催化剂进料系统的控制及运行分析

Control and operation of main catalyst feed system in gas phase PP plant

通过对注入反应器的主催化剂、助催化剂的进料方式及注入量数据收集,分析了主催化剂进料系统质量流量计测量飘移产生的原因,为仪表预知维护提供了可靠依据,为装置平稳运行提供可靠保证。

This article describes the feed mode of main catalyst and cocatalyst in reactor as well as the consumption of catalyststo provide the causes of measuring drift of the mass flow-meter in main catalyst feed system,which offers guidance for predictivemaintenance of instruments and smooth operation of the polypropylene（PP）plant.
