Models of the equation of state (EOS) type, used for describing fluid phase equilibria, typically assume that the system behavior can be described from binary contributions only. This is not enough for obtaining good ...

The use of mixed near-critical solvents such as CO2 + propane, for vegetable oil extraction processes, has the advantage of the good solvent capacity of propane together with a nonflammable vapor phase due to the CO2 ...

In the present work, the group contribution with association equation of state (GCA-EoS) is extended to represent phase equilibria in mixtures containing acids, esters, and ketones, with water, alcohols, and any number of ...

The transesterification of vegetable oils, esterification of fatty acids and glycerolisis reactions, with supercritical alcohols, are of interest in the production of fine chemicals and biodiesel. The partial miscibility ...

In this work, we systematically study the phase behavior of the binary systems homologous series of methane with heavier n-alkanes, by considering the appearance of fluid and pure solid phases. The Peng-Robinson (PR) and ...
