The statistical associating fluid theory SAFT-VR developed by the group provides one of the most sophisticated and accurate descriptions of complex fluids for industrial applications. It is a widely used equation of state with over 800 citations to the original papers. SAFT has been used in applications ranging from the production of replacement refrigerants, to describing surfactant solutions. The focus of this research proposal is the molecular modelling of interfaces and phase behaviour in oil-water-surfactants (CiEj). These systems are currently being used ahead of scale inhibitor squeeze treatments of oil fields to improve the lifetime of the well. This is linked to the specific phase behaviour, i.e., the proximity of the lower critical solution temperature. SAFT would be used to model the phase behaviour of oil-water-surfactants. The effect of salinity (using MSA theory), pressure and temperature on the phase boundaries would be invaluable in formulating effective squeeze treatments for a given field. The most ambitious part of the proposal is to describe the interfacial and wetting behaviour of the surfactant at the air-water/water-oil interfaces (combining DFT with SAFT). This is of prime importance in understanding of the accummulation of the surfactant at the various interfaces, and of the solubilisation process.
