This work aims to address the design and control challenges caused by the integration of phenomena and the loss of degrees of freedom (DOF) that occur in the intensification of membrane reactor units. First, a novel approach to designing membrane reactor units is proposed. This approach consists of designing smaller modules based on specific phenomena such as heat exchange, reactions, and mass transport and combining them in series to produce the final modular membrane-based unit. This approach to designing membrane reactors is then assessed using a process operability analysis for the first time to maximize the operability index, as a way of quantifying the operational performance of intensified processes. This work demonstrates that by designing membrane reactors in this way, the operability of the original membrane reactor design can be significantly improved, translating to an improvement in achievability for a potential control structure implementation.
这项工作旨在解决膜反应器单元强化过程中由于现象整合和自由度（DOF）丧失所导致的设计和控制挑战。首先，提出了一种设计膜反应器单元的新方法。该方法包括基于热交换、反应和质量传递等特定现象设计较小的模块，并将它们串联组合以生产最终的模块化膜基单元。然后，首次使用过程可操作性分析对这种设计膜反应器的方法进行评估，以最大化可操作性指标，作为量化强化过程操作性能的一种方式。这项工作表明，通过以这种方式设计膜反应器，原始膜反应器设计的可操作性可以得到显著改善，这意味着在实施潜在控制结构时可实现性的提高。
