First-principles-based process simulation of electrolyte systems is a key enabling technology for chemical engineers to design, debottleneck, and optimize chemical processes with electrolytes. In the development of process simulation models for electrolytes, a key challenge is the availability of accurate and rigorous thermodynamic models.
This article:
• summarizes the thermodynamics of mixed electrolyte systems
• identifies critical thermodynamic parameters and the equations and relationships used to determine these parameters
• outlines the steps to develop thermodynamic models of mixed solvent electrolyte systems
• provides three examples to illustrate these steps.
