气相法聚丙烯工艺装置先进过程控制（APC）的应用研究

摘要

先进过程控制（APC）技术针对气相聚合技术和反应器系统中的特点，通过综合反应控制器来实现过程反应系统的闭环控制，达到进一步优化产品出料、生产时间、树脂（产品）质量等级、产品牌号的切换、产品一致性、单位能效等目的。%In accordance with the characteristics of gas polymerization technique and reactor system, advanced process control (APC) technique can realize the closed loop control for process reaction system through integrated reaction control package. In this way, the optimizations of product discharge, production duration, resin quality class, change of product name, product uniformity and unit energy consumption were realized.
