Process simulation software designs equipment, simulates operations, optimizes a plant's configuration (heat exchangers network, for example), estimates operating and capital expenses, and serves as an educational tool. However, mastering the theoretical background minimizes common mistakes such as applying an incorrect thermodynamic method, selecting improper algorithms in the case of tear systems, and setting irrational system specifications. Engineers and researchers will exploit this tool more often in the future as constant advancements in simulation science as well as new models are released continually. Process simulators make it easier to build digital twins and thus will facilitate the implementation of the industry 4.0 guidelines. We highlight the mathematical and technical features of process simulators, as well as the capabilities and the fields of application. A bibliometric map of keywords from articles citing Aspen+, Aspen plus, Hysys, and Pro/II indexed by Web of Science between 2017 and 2020 identified the main research clusters, such as design, optimization, energy or exergy, biomass; H₂ and CO₂ capture, thermodynamics; and separations and techno‐economic analysis.

化学工程中的实验方法：过程模拟

过程模拟软件设计设备，模拟操作，优化工厂的配置（例如，热交换器网络），估算操作和资本支出，并用作教育工具。但是，掌握理论背景可以最大程度地减少常见错误，例如应用错误的热力学方法，在撕裂系统的情况下选择不正确的算法以及设置不合理的系统规格。随着仿真科学的不断进步以及新模型的不断发布，工程师和研究人员在将来会越来越多地使用此工具。过程仿真器使构建数字孪生模型变得更加容易，因此将有助于实施工业4.0准则。我们重点介绍过程模拟器的数学和技术功能，以及功能和应用领域。引用了Aspen +，Aspen plus，Hysys和Pro / II的文章中关键字的文献索引图Web of Science在2017年至2020年之间确定了主要的研究领域，例如设计，优化，能源或火用，生物质。H ₂和CO ₂捕获，热力学；分离和技术经济分析。
