The gas and liquid solubility relations in hydrocarbon‐water systems

Abstract

Abstract The typical solubility boundaries of binary simple hydrocarbon‐water systems are outlined for temperatures and pressures ranging into the neighborhood of the critical point for pure water. These systems are characterized by two unique states, a critical vaporization end point and a critical solution end point. The former defines the limit of mutual solubility of two liquid phases, and the latter defines a point of complete solubility at a minimum pressure. Experimental P ‐ T ‐ x data for cyclohexane‐water and n ‐hexane–water mixtures are presented.
