Abstract

This work describes an approach towards experimental implementation of real time control studies conducted on a batch polymerization reactor. The information is related to the controlling of molecular weight for styrene acrylonitrile copolymer polymerization system in a batch reactor generated under a varied range of temperatures, reactant concentrations and retention times. The operating conditions of 6 hrs and temperature of 343 K for yielding a molecular weight in the range of 39,900-40,000 gmol is established using simulation studies. A real time control facility consisting of a batch reactor, data acquisition software "LabVIEW" and a PC for monitoring and control is used to implement these operating conditions. The resulting product is analyzed by gel permeation chromatography (GPC). The data generated can be used by researchers, academicians and industry for generating control strategies, automation and scale up of polymerization reactors.

摘要

这项工作描述了一种在间歇聚合反应器上进行实时控制研究的实验实施方法。该信息涉及在不同温度、反应物浓度和停留时间下，间歇反应器中苯乙烯-丙烯腈共聚物聚合体系的分子量控制。通过模拟研究确定了在6小时的操作条件和343K的温度下，可得到分子量在39,900 - 40,000 g/mol范围内的产物。使用由间歇反应器、数据采集软件“LabVIEW”和用于监测与控制的个人计算机组成的实时控制设备来实施这些操作条件。所得产物通过凝胶渗透色谱法（GPC）进行分析。研究人员、学者和工业界可以利用生成的数据来制定控制策略、实现聚合反应器的自动化和放大生产。
