Process intensification principles have been considered as a valuable tool to improve the economic and sustainability factors in process systems engineering. In this work, an intensification methodology that minimizes the number of equipment units required for the transformation of raw materials into products is presented. On the basis of phenomena building blocks, intensification opportunities are detected and explored to integrate tasks into fewer pieces of equipment, and the effects on process economics and sustainability metrics are assessed. The methodology is applied for the intensification of a process consisting of the aldolization of an ethylene glycol and 1,2-butanediol mixture with acetaldehyde to produce 2-methyl-1,3-dioxolane (2MD) and 4-ethyl-2-methyl-1,3-dioxolane (4EMD). It is shown how an original flowsheet with one chemical reactor and three distillation columns is gradually transformed into an intensified process that provides an alternative with superior economic and sustainability metrics.

减少设备数量的强化方法及其在生产二氧戊环产品过程中的应用

过程强化原则已被认为是改善过程系统工程中的经济和可持续性因素的宝贵工具。在这项工作中，提出了一种强化方法，该方法可将原材料转化为产品所需的设备单元数量减至最少。基于现象构建块，检测并探索强化机会，以将任务集成到更少的设备中，并评估其对过程经济性和可持续性指标的影响。该方法学适用于强化工艺，该工艺包括乙二醇和1,2-丁二醇混合物与乙醛的醛醇缩合反应，生成2-甲基-1,3-二氧戊环（2MD）和4-乙基-2-甲基- 1,3-二氧戊环（4EMD）。
