The manufacturing industry is challenged by increasing costs of scarce resources, rapid change, and tight competition in global markets, and the need for efficient and sustainable process design and operating strategies. Addressing these challenges has been the focus of process intensification (PI). Polymerization processes face the additional challenge of meeting tight product specifications, which are dictated by the demands of high quality and advanced materials. Meeting these specifications requires the incorporation of complex molecular weight distribution (MWD) models based on population balances of all the polymer chains. Addressing these challenges through process intensification requires the development and application of efficient, robust, and powerful optimization strategies and modeling frameworks, leading to an essential strategy for process intensification of polymerization systems. This survey presents the development and application of novel optimization strategies for model development, process synthesis and design, and the operation of polymer processes. The effectiveness of these optimization-based approaches will be demonstrated on a slurry process for high density polyethylene (HDPE), where significant advances in process intensification have been realized. Future directions are given, with the aim of benefiting both research and application in this field.

具有嵌入式分子量分布模型的聚合过程的过程强化：一种先进的优化方法

制造业面临着以下挑战：稀缺资源，快速变化和全球市场的激烈竞争带来的成本增加，以及对高效，可持续的流程设计和运营策略的需求。应对这些挑战一直是过程强化（PI）的重点。聚合工艺面临着满足严格的产品规格的额外挑战，这取决于高质量和先进材料的要求。满足这些规范要求基于所有聚合物链的总体平衡，并入复杂的分子量分布（MWD）模型。通过强化流程来应对这些挑战，需要开发和应用高效，强大，强大的优化策略和建模框架，导致了增强聚合系统过程的基本策略。这项调查介绍了用于模型开发，过程合成和设计以及聚合物过程操作的新型优化策略的开发和应用。这些基于优化的方法的有效性将在高密度聚乙烯（HDPE）的浆料工艺中得到证明，该工艺已在工艺强化方面取得了显着进步。给出了未来的方向，目的是使该领域的研究和应用都受益。这些基于优化的方法的有效性将在高密度聚乙烯（HDPE）的浆料工艺中得到证明，该工艺已在工艺强化方面取得了显着进步。给出了未来的方向，目的是使该领域的研究和应用都受益。这些基于优化的方法的有效性将在高密度聚乙烯（HDPE）的浆料工艺中得到证明，该工艺已在工艺强化方面取得了显着进步。给出了未来的方向，目的是使该领域的研究和应用都受益。
