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‐CO 2 .
