SAFT (Statistical Association Fluid Theory) is a class of Equations of state used for the interpolation, extrapolation and prediction of phase equilibria and thermophysical properties of mainly gases, liquids, but also solids. Since the first version of SAFT published in 1989, numerous new versions have been developed. Compouds are modeled in SAFT by a chain of spherical beads with optional patchy sites (associating sites). The compound-specific parameters are the size and number of the beads, and the form of the potential for the interaction between the beads. In comparison to other equations of state, SAFT offers improvements at high pressures and also for associating compounds (e.g., hydrogen bonds and donor-acceptor clustering).

Paragraph, Mentioning Wertheim, equation of state, chemical engineering, possible links with other methods, mention link to molecular simulation

A large variety of SAFT version is available for which parameter sets are not necessarily compatible. Motivations have been mentioned to make versions better comparable and reduce the number of variants to make its application easier.

Interpolation, extrapolation or prediction of thermodynamic properties as saturated liquid densities, vapour pressure, heat capacity, speed of sound, compressibility, critical properties,

With SAFT alone only homogeneous properties can be described; when linked to DFT, DGT, SGT or molecular simulation also heterogeneous properties as density profiles are accessible.

Saft versions
Saft versions differ by number of perturbation terms, it's reference fluid, mathematical separation of reference and perturbation terms, target properties it has been optimised for and extra terms added to account for additional effects or makeover properties accessible.

Saft conferences
General Saft conferences are held every 5 years, with conferences on subtopics in shorter intervals SAFT2015 Houston as 25th anniversary, organised by and hold at Roce University, with Keynote talk by Keith Gubbins.
