Equilíbrio de fases a altas pressões da mistura CO2 + etanol

Abstract

The analysis of phase equilibrium of mixtures is important for future studies based on the prevention of hydrates formation. This approach allows minimize risk and maximize productivity, important questions to Brazil during the pre-salt exploration. The methodology used for determining the phase transition system CO2 + ethanol was the synthetic static visual method. The results were compared with the literature. It were determined curves of phase transition for system supercritical CO2 + ethanol. The thermodynamic modeling allowed obtaining data of fugacity for each composition of the system at different temperatures.
