On the benefits of Counter-Current regeneration on a partial pressure swing Adsorptive reactor (PPSAR) with application to the Water Gas Shift reaction

Abstract

This work demonstrates the benefits of carrying out counter-current over co-current regeneration during the operation of a Partial Pressure Swing Adsorptive Reactor with application to the Water Gas Shift reaction. Our previously introduced dynamic, multidomain, multiscale model is used to compare two theoretical case studies employing co-current and counter-current regeneration modes, respectively. The process conditions for the two regeneration case studies remain identical apart from the employed regeneration modality. This allows for the elucidation of the process performance benefits arising solely from the adaptation of the employed regeneration mode.
