- Abstract
Current social needs, as well as political and environmental restrictions, have led to the generation of products within a framework of sustainability, and favoring production processes based on renewable raw materials. During the process design work, the role of the dynamic properties of a process, together with some other metrics, is not always considered. However, several studies have shown that there is a certain relationship between the dynamics and controllability of the process and its sustainability. In this work, the dynamic properties of different separation schemes for the purification of 2,3-BD from biomass fermentation are evaluated. The study allowed determining the best alternatives for the eventual implementation of these schemes, as well as the role of controllability concerning other sustainability indicators. As result, it was found that schemes that include a thermal coupling in their topological design allow a general improvement of all sustainability indicators. In addition, it was observed in this case study that process intensification contributes significantly to the fulfillment of various sustainability indicators. • It was obtained the control properties of separation alternatives to purify 2,3-Butanediol, the thermally coupled alternatives resulted as the most balanced alternatives • The sustainable evaluation allows considering a thermal coupling as a fundamental step in process design of a sustainable process. • The most intensified alternative did not result as the most sustainable alternative
