聚丙烯催化剂计量系统运行分析

Operation analysis of polypropylene catalyst metering system

聚丙烯催化剂活性高,耗量小,单耗为0.033 kg/t PP,催化剂使用需要配制成膏状物,为了准确计量催化剂,意大利Basell公司专门为液相法和气相法聚丙烯工艺设计了一套程序复杂、操作难度大的催化剂计量系统,本文就如何运行好催化剂计量系统及生产中常出现的问题进行了分析和探讨。

The polypropylene(PP)catalyst is highly active,and its consumption is as small as 0.033 kg/t PP.The catalyst in use is prepared as paste.In order to accurately measure the catalyst,Italian Basell Company specialized in liquid phase and gas-phase polypropylene process designed a complicated,difficult to operate catalyst metering system.The paper presents the operating principles,logic,and accurate operation of the catalyst metering system and discusses the problems in PP production.
