Abstract
Water–carbon dioxide binary mixtures are important for a number of industrial and environmental applications. Accurate modeling of the thermodynamic properties of water–carbon dioxide binary mixtures is difficult because of the highly non-ideal intermolecular interactions.
Authors describe the use of two models based on the Statistical Associating Fluid Theory (SAFT) to correlate reliable experimental vapor–liquid equilibria (VLE) and liquid–liquid equilibria (LLE) data in the temperature range 298–533 K.

ABSTRACT
Knowledge of high-pressure phase equilibria is crucial for the design and optimization of high-pressure chemical and separation processes, carbon capture and storage, hydrate formation, applications of ionic liquids, and geological processes.
Authors review a variety of methods to measure phase equilibria at high pressures. They discuss the measurement principles, advantages, challenges, and error sources.  They provide examples of application areas
