Hydrocarbon-Water Solubilities At Elevated Temperatures Near the Three-Phase Equilibrium Pressure

Abstract

The purpose of this work was to establish a reliable experimental apparatus and procedures for measuring liquid-liquid equilibrium data at ambient and elevated temperatures and pressures. A continuous flow apparatus has been designed and constructed to obtain mutual solubilites at temperatures from ambient to 623 K and pressures up to 13.8 MPa. The accuracy of the apparatus and methods used was determined by measurements on the well-documented benzene-water system. Mutual solubility data have also been measured for the aqueous binary systems involving decane and I-hexene at temperatures up to the three-phase critical end point.
