Dynamic Modeling of Electrochemical pH‐Swing Extraction

Chemie Ingenieur Technik, vol. 92, pp. 1953–1961

Abstract

Abstract Electrochemical unit operations have the potential to enable zero‐waste downstream processing of bio‐based products. A profound understanding of the underlying phenomena is inevitable for technological development. This work presents a dynamic model for the electrochemical pH‐swing extraction on the example of succinic acid. Model results are well in line with experimental data. In addition, dynamic modeling enables the examination of mass transport kinetics and provides insights into the interactions between aqueous pH‐ and liquid‐liquid extraction equilibria.
