Phase equilibrium, phase densities and surface tensions of hydrcaorbon-hydrocarbon (HC-HC) and hydrocarbon-CO2 (HC-CO2) vapor-liquid system have great importance in separation, purification and dissolution processes. In this work, a local composition model was introduced into the volume translated Peng-Robinson(VTPR) equation of state(EOS) to calculate the phase equilibrium and phase densities. And then the local composition combined with VTPR EOS was used to predict the surface tensions based on the gradient theory. The results show that the introduction of the local composition model can achieve accurate calculation of phase equilibrium, phase densities and surface tensions for binary HC-HC and HC-CO2 mixtures.

Liquid or supercritical carbon dioxide (sc-CO2) has attracted much interest as environmentally benign alternative for conventional organic solvents. However, low solubility in carbon dioxide, especially polar compounds, is a limitation to the wide practical application of sc-CO2. These solubility problems have been overcome by employing some specialised CO2-soluble surfactants to form reverse micelles or water-in-CO2 (w/c) microemulsions, which could accelerate the development of a broad range of CO2-based processes.
