The high-pressure phase equilibria of fluids [1] has important consequences, ranging from practical applications to frontier sciences. A well-known example of the former is the removal of caffeine from coffee via supercritical extraction whereas modelling the chemical behavior of Saturn and Jupiter is a more exotic application. The diversity of phenomena expands as the number of components in increases. So-called â??islands of immiscibilityâ? are observed when three of more component are involved resulting from the complex interplay of mixing and de-mixing processes. The phenomena are ultimately governed by fundamental differences in the interactions between molecules and experimental phase behavior data have provided the impetus for both the development of theory [2] and molecular simulation [3] techniques. This work highlights progress in understanding phase equilibria at high prressures, emphasising new developments [4] that may challenge our understanding of phenomena at high pressures.
