This work proposes a methodology to perform exergy analysis of an intensified isothermal reactive extraction process. The method involves two steps. The first one includes the modeling and adaptation of a material utilization diagram (MUD) to allow the estimation of exergy losses and gains for each component and for the overall process. In the second step, the utilization of exergy of the different reactive extraction configurations was estimated through the calculation of exergy indicators. The strategy estimates the effect of the operation and design parameters on the indicators, and determinates the process configuration with the best utilization of exergy. The method was applied to the butyl acetate and n-amyl-acetate reactive extractions processes, in single and multiple stage operations. For both cases of study, improvements in the exergy indicators were obtained by using a countercurrent configuration with two stages. Exergy indicator of 88.45% and 82.97% for butyl acetate and n-amyl-acetate, respectively, were determined for product stream. The method proposed can support the search for optimal operation and design parameters, and help the development of highly efficient reactive extraction processes.

这项工作提出了一种方法，可以对强化的等温反应萃取过程进行火用分析。该方法包括两个步骤。第一个包括对材料利用图（MUD）进行建模和调整，以允许估计每个组件和整个过程的火用损失和收益。第二步，通过计算火用能指标，估算了不同反应萃取配置的火用利用率。该策略估计操作和设计参数对指标的影响，并确定最佳配置以充分利用火用。该方法已应用于乙酸丁酯和乙酸正戊酯的反应萃取工艺中，分为一步和多步操作。对于这两种研究案例，通过使用具有两个阶段的逆流配置，获得了对火用指标的改进。测定产物流的乙酸丁酯和乙酸正戊酯的火用指示剂分别为88.45％和82.97％。所提出的方法可以支持对最佳操作和设计参数的搜索，并有助于开发高效反应萃取工艺。
