Summary
Water + hydrocarbon mixtures exhibit complex phase behavior at high temperatures and pressures. An in depth knowledge of the phase behavior for water + hydrocarbon mixtures is important for the design of the process of oil sand and bitumen upgrading using supercritical water.
However, there is very little experimental data of the phase equibria for water + hydrocarbon mixtures at high temperatuers and pressures.
Now, Yusuke Shimoyama and colleagures at Tokyo Tech discovered a liquid ? liquid phase transition for water + light hydrocarbon + heavy hydrocarbon mixture at a constant temperature.
