Résumé

The Progressive Freeze Concentration (PFC) process enables a gradual removal of water content present in a liquid solution in the form of ice, with the efficiency of the process dependent on the intrinsic partition coefficient (𝐾!). The current approach to calculating 𝐾! is constrained by its limited capability to capture the impact of ice growth rates, which often results in inaccurate predictions. A modified framework is proposed to estimate 𝐾! in terms of the ice growth rate and solute concentration in the ice and liquid phases. The results demonstrated that 𝐾! is proportional to the ice growth rate within the studied range. A sigmoidal function approximator was utilized to extend the 𝐾! estimation beyond the experimental range and identify optimal operating conditions for a PFC process. The proposed approach can significantly improve the accuracy of the existing models and the performance efficiency of the PFC process.
