中文摘要	聚合过程是强放热的非线性过程,这类过程一般存在多稳态现象,且不同的稳态具有不同的局部稳定性。采用气相卧式搅拌釜聚丙烯反应器的Innovene工艺是目前生产聚丙烯最先进的工艺之一。本文开展了该反应器的稳态模拟与多稳态分析研究,对平稳生产、新牌号开发都有着重要的意义。利用Polymer Plus建立了更符合实际且适用于稳定性研究的气相卧式搅拌釜聚丙烯反应器非等温模型,以GPC数据进行聚丙烯反应网络的参数反演。通过灵敏度分析求解系统的多稳态解,通过推理分析的方式判断各个反应区域的稳定性,解决了该问题多稳态研究中的稳定性判断问题,并通过稳定性分析,从本质安全角度出发识别出适于操作的稳态点范围。; The strongly exothermic polymerization process is a nonlinear process which generally have multi-stable phenomenon. Different steady state has different local stability. The Innovene process which uses gas-phase horizontal stirred bed reactor, is one of the most advanced technology for propylene polymerization. A reactor model using Polymer Plus was built. This model is more consistent with actual cases and suitable for steady-state multiplicity analysis. The reaction parameters were obtained by fitting the GPC data of products. The steady-state multiplicity characteristics by the sensitivity analysis of steady-state model were also analyzed. An inferential analysis method for judging the stability of steady-state solutions was proposed, and the intrinsically safe operating range for each reactor area was identified finally. This is an important work for the stable operation and the development of new grades of polypropylene.
