摘要

本文通过两个化工过程实例——苯乙烯悬浮间歇聚合反应过程和乙苯脱氢制苯乙烯反应过程

说明以现代控制理论的估计技术为基础的软测量技术已推广到实际工业生产.它为指导过程操作、监控和优化控制提供了通常不能直接测量的、但在过程操作中必需的与产品质量直接有关的过程信息

如聚合物链长分布、催化剂活性等.文章介绍了两个过程建模、控制方案设计和研究结果

对其在工业过程中应用积累了一定的经验.

Abstract

In this paper

two examples in chemical processes (styrene suspension batch polymerization and ethylhenzene dehydrogenation) are given to indicate the extended application of the model-based measuring technique using state estimation to practical industrial objects. It can provide for operation supervision

monitoring and optimal control the information about a process which is usually immeasurable but necessary to process operation. Such information is directly related to product quality

e. g.

chain length distribution of polymer

catalyst activity

inversion rate of reaction process

selectivity

etc. In this paper the modelling

control design and implementation for the two reaction processes are also introduced. Some experience for the application in industrial processes has been accumulated.
