Abstract

A model is derived which enables the calculation of solid/fluid phase equilibria in multicomponent systems over the entire pressure range. The model requires only generally available caloric data of the pure solids. The non-ideality of the fluid phase is described using the SAFT equation of state. The model is verified on experimental phase equilibrium data of binary and ternary n-alkane mixtures as well as on the system naphthalene-CO2.
