Vapor-Liquid-Solid Equilibria of Sulfur Dioxide in Aqueous Electrolyte Solutions

open access: yes, 2000
The Extended UNIQUAC model for electrolyte systems, combined with the Soave-Redlich-Kwong equation of state is used to describe the complex vapor-liquid-solid equilibria of sulfur dioxide in electrolyte solutions.

Thermodynamic Model for the Ammonia-Water System

open access: yes, 2000
The ammonia-water system is described by the Extended UNIQUAC model, which is an electrolyte model, formed by combining the original UNIQUAC model, the Debye-Hückel law and the Soave-Redlich-Kwong equation of state.

Ternary Liquid-Liquid Equillibria for (Water + Methanol + β-Citronellol) at 283.15 and 313.15 K

open access: yes, 2011
Liquid-liquid equilibrium tie-line data are reported for ternary mixture of (water + methanol +β-citronellol) at 283.15 and 313.15 K. The miscibility for the ternary (water + methanol + β-citronellol) LLE was increasing as the the temperature increased ...

Vapor-Liquid equilibrium in DEEA/H2O/CO2 system; Experiments and modeling [PDF]

open access: yes, 2011
Experiment data for vapor-liquid equilibrium (VLE) of CO2 were conducted for DEEA 5M and 2M.The study was performed in two VLE apparatuses from 40 to 120 °C with atmospheric VLE apparatus and high pressure VLE apparatus.

A THERMODYNAMIC MODEL TO PREDICT WAX FORMATION IN PETROLEUM FLUIDS

open access: yes, 2001
Some years ago the authors proposed a model for the non-ideality of the solid phase, based on the Predictive Local Composition concept. This was first applied to the Wilson equation and latter extended to NRTL and UNIQUAC models.

Modeling the phase equilibria of CO2 and H2S in aqueous electrolyte systems at elevated pressure

open access: yes, 2009
The solubility of carbon dioxide (CO2) and hydrogen sulfide (H2S) in basic aqueous electrolyte solutions is determined by a combined phase and reaction equilibrium.

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). The activity
