Preliminary framework for quantitative sustainable design of redox-mediated electrodialysis for biorefinery separations

Electrodialysis (ED) is an electrochemical unit operation that may help advance the production of bio-based organic acids, including succinic acid. Redox-ED is one particular class of electrochemical technology that can contain novel layer-by-layer (LBL) membranes and employ a modified cell pair and redox-flow platform. Environmental and chemical engineering industries are gaining interested in modeling redox-ED as it possible that modern advances in the novel layer-by-layer membrane technology can be economically and environmentally feasible when implemented in the downstream separations of fermentation-based processes. This work couples an empirical model of technology performance with a framework for quantitative sustainable design of downstream redox-ED and will provide a way to define the opportunity space for this novel technology. Findings include a baseline levelized cost estimation of 5.76 USD∙kg SA-1 and technology targets for achieving a levelized cost of 1.19 USD∙kg SA-1 with advances in flux of succinic acid (SA) and specific energy consumption. In coupling an empirical model with a quantitative sustainable design framework, this work aims to give a sense for the feasibility of redox-ED implementation at an industrially relevant scale to prioritize future research directions by characterizing economic and environmental indicators for sustainability.
