In this chapter we provide some background on the development of Wer-theim s theory of association and then review the main versions of the SAFT equation of state used in the current literature. Rather than focus on the systems that have been studied using the different versions, which was recently reviewed by Tan and co-authors, we have striven to provide a survey of the latest theoretical developments directed at enhancing the capability of the SAFT framework for the study of increasingly complex fluids. [Pg.216]

2 Statistical Mechanical Theories of Association and Wertheim s Theory [Pg.216]

When eq 8.3 is substituted into the cluster expansion for the distribution functions in the fluid, and simplified through cancellations in graphs by taking into account eq 8.2, the result is a formal graphical expansion for the pair distribution function in terms of renormalized hydrogen-bond /-functions. This concept of saturation at the dimer level is a key element in Wertheim s theory, discussed below. [Pg.217]
