摘要: Abstract Certain ternary mixtures of near-critical carbon dioxide + n -alkanols tetradecane have been found to display unexpected fluid multiphase equilibria. For instance, it was that in the systems with decanol, octanol, or heptanol three-phase liquid-liquid-vapor surface contains a two-phase liquid-vapor region which is completely bounded by closed loop critical endpoint locus type liquid = vapor ( l 1 2 g ). The occurrence such “holes” indicate at conditions encountered supercritical operations, phase behavior might be more complex than expected, and may consequences process design.
