“…This calculation method should be used under liquid component-rich conditions. Because experimental data ,,− for the homogeneous phase of the CO 2 + solvent systems show density behavior changes as the CO 2 richness increases, the density data for different CO 2 compositions ( x 1 = 0-saturation) under constant pressure conditions can be used to calculate further thermophysical properties, including the excess and partial molar volumes.…”

We investigated the densities, viscosities at atmospheric pressure, high-pressure densities, and CO2 solubilities of a deep eutectic solvent comprising choline chloride (ChCl) and ethylene glycol (EG) at a 1:2 molar ratio (ChCl2EG). The measured CO2 solubility of ChCl2EG was compared with several references. The saturated densities of the vapor and liquid phases of the CO2 + ChCl2EG system were measured using a static-circulation-type apparatus equipped with two vibrating-tube densimeters. The saturated densities of the liquid phase were expressed using a newly developed density-correlated equation. The present study proposes a method for calculating the liquid density of the homogeneous phase for asymmetric mixtures composed of a nonvolatile solvent and gaseous or supercritical CO2. The liquid density of the homogeneous phase obtained using the density-correlated equation could be used to calculate the excess and partial molar volumes, which are essential properties for analyzing liquid structures.

Multiphase Equilibria Modeling with GCA-EoS. Part II: Carbon Dioxide with the Homologous Series of Alcohols

Modeling multiphase equilibria of mixtures comprising carbon dioxide (CO2) and organic compounds is a challenge for any equation of state. CO2 shows a highly nonideal phase behavior with most organic compounds, which is even more pronounced with hydrogen-bonding compounds. In this work, we have extended the Group-Contribution with Association equation of state (GCA–EOS) to represent vapor–liquid, liquid–liquid, and vapor–liquid–liquid equilibria of CO2 mixtures with primary alcohols. The final set of parameters has been challenged against an experimental database covering C1–C16 primary alcohols, temperatures from 230 to 573 K, and pressures up to 400 bar. Particular attention has been given to describe the critical curves for each binary system correctly, which means attaining the phase equilibria transformation of the CO2 + 1-alcohol homologous series as the alcohol alkyl chain length increases. This parametrization strategy allows reducing the risk of incorrect liquid–liquid split predictions. In addition, using a single set of parameters, fitted to binary data of CO2 with normal alcohols, the model is able to predict the phase behavior of binary mixtures not included in the parametrization procedure, comprising normal and branched alcohols. The GCA-EOS predicts properly the overall phase behavior, that is, the binary critical curves, without losing accuracy in the prediction of saturation points.
