A general approach to multiphase equilibrium calculations with particular application to vapour-liquid-liquid and liquid-liquid-liquid systems is presented. The capabilities of the new technique to correctly predict and calculate complex phase equilibrium are tested on five highly non-ideal systems, relevant to supercritical fluid extraction. The thermodynamic models applied are the recently proposed MHV2 model and the Redlich-Kwong-Soave cubic equation of state.
