Over the past several decades, many modifications have been proposed in SMB chromatography in order to effectively separate a binary mixture. However, the separation of a multi-component mixture using SMB is still one of the major challenges. Recently, a computational study was performed which compared various existing isocratic ternary separation operating schemes (including the JO process) in terms of the maximum throughput attained, and Generalized Full Cycle strategy was proposed based on a systematic design, which was found to have significant improvement over existing strategies [Agrawal and Kawajiri (2012)]. Nevertheless, the operating strategies were not experimentally validated. In this study, we validate both JO and Generalized Full Cycle SMB systems experimentally. A simultaneous optimization and model correction scheme has been implemented to arrive at the optimal operating condition which satisfies the optimal productivity as well as the desired purity and recovery of products experimentally.
在过去的几十年中,人们提出了许多 SMB 色谱中的改进方法,以便有效地分离二元混合物。然而,使用 SMB 分离多组分混合物仍然是主要挑战之一。最近,进行了一项计算研究,比较了各种现有的等度三元分离操作方案(包括 JO 过程)在达到的最大吞吐量方面的情况,并基于系统设计提出了广义全循环策略,发现该策略比现有策略有显著的改进[Agrawal 和 Kawajiri(2012)]。然而,这些操作策略尚未经过实验验证。在这项研究中,我们通过实验验证了 JO 和广义全循环 SMB 系统。实现了一种同时优化和模型校正方案,以达到满足最佳生产率以及实验所需的产品纯度和收率的最佳操作条件。
