基于Polymer plus等规聚丙烯预聚工艺的模拟与优化 化学工程与工艺专业

摘要本文主要使用 polymer plus 化工软件，对上海石化 1PP 法聚合等规聚丙烯聚合工艺开展模拟研究，创建科学模型。通过改变催化剂、物料进料量、温度、压力等方式，对聚丙烯的重均分子量、多分散性指数、产率的影响进行灵敏度分析。模拟结果表明：模拟结果与实际生产参数影响的趋势一致，虽有一定差异但结果具有一定的参考价值，为实际生产提供了有效的数据证明。关键词：等规聚丙烯，polymer plus, 模型建立，灵敏度分析，聚合模拟IAbstractBased on the polymer plus chemical software, this paper simulates and analyzes the isotactic polypropylene polymerization process of Shanghai Petrochemical 1PP polymerization, and establishes a simulation model. By changing the catalyst, material feed, temperature, pressure, etc., the sensitivity analysis of the influence of the weight average molecular weight, polydispersity index, and yield of polypropylene was carried out. It shows that the results of simulation are basically consistent with the trend of the industrial production’s influence. Although there are certain differences, the results have certain reference values and provide effective data for actual production.Keywords: Isotactic polypropylene, Polymer Plus, model establishment, sensitivity analysis, simulationII目录1 前言..............................................................................错误!未定义书签。1.1 研究背景...........................................................................错误!未定义书签。1.2 聚丙烯预聚工艺介绍.......................................................错误!未定义书签。1.3 国内外聚丙烯生产装置及工艺介绍................................错误!未定义书签。1.4 聚丙烯催化剂....................................................................错误!未定义书签。1.5 聚丙烯生产技术的发展方向............................................错误!未定义书签。1.6 技术路线............................................................................错误!未定义书签。2 ...
