Impact of extended long-range electrostatics on the correlation of liquid-liquid equilibria in aqueous ionic liquid systems

open access: yes, 2023
Recently an improved long-range model for electrolyte solutions was developed that is applicable from infinite dilution to pure salt. This paper tests this claim for the first time applying it to the calculation of liquid-liquid equilibria for mixtures ...

Evaluation of Parameter Fitting Procedures for Rigorous Equilibrium Model Development

open access: yes, 2012
An automated procedure for optimizing interaction parameters in the extended UNIQUAC model is proposed. This method avoids manual manipulation and guessing of parameters.

Prediction of thermodynamic properties using a modified UNIFAC model: application to sugar industrial systems

open access: yes, 1999
A modified UNIFAC model recently proposed in the literature is used to predict thermodynamic properties of aqueous solutions containing different sugars, commonly used in food industries (D-galactose, D-mannose, D-xylose, maltose and lactose), and for ...

Comparison of models for calculation of the thermodynamic properties of NH3-CO2-H2O mixture

open access: yes, 2016
Couple of models have been developed to calculate thermodynamic properties of NH3-CO2-H2O systems. These models are typically an equation of state for the vapor phase and an activity coefficient model for the liquid phase (Que & Chen, 2011).

Solubility Measurements and Modeling of Zinc, Lead and Iron Sulfides at High Temperatures and High Pressures [PDF]

open access: yes, 2016
Solubility measurements of sulfides in aqueous solutions are necessary to understand the behaviour of these scaling minerals in geothermal and oil reservoirs. The low solubility levels of Zinc Sulfide (ZnS), Lead Sulfide (PbS) and Iron Sulfide (FeS) make
