Prediction of the diffusion coefficients in multicomponent liquid refrigerant solutions

“…The derivatives of the activity coefficients of the ionic species in Eqs. ( 29), (39), and ( 40) can be evaluated by the extended UNI-QUAC model (Peralta et al, 2007) taking into account the electroneutrality condition given by Eq. ( 2).…”

Prediction of the freezing point of multicomponent liquid refrigerant solutions

“…A modified version of the extended UNIQUAC model (Nicolaisen et al, 1993;Thomsen, 1997) developed by Sander et al (1986), studied by Thomsen and co-workers, and proposed for the prediction of freezing point of multicomponent solutions (Peralta et al, 2007), was used. In this model, it is considered that the excess 0260-8774/$ -see front matter Ó 2010 Elsevier Ltd. All rights reserved.…”

“…process simulation and optimization for a wide range of physical conditions to achieve the best possible operational conditions). Peralta et al (2007) presented a thermodynamic model of excess Gibbs energy for predicting heat capacity, density and freezing point of liquid refrigerants used in ICF process. The model was checked for binary aqueous systems commonly used in chilling and freezing of foods.…”
