Abstract
A method for calculation of the phase distribution in multiphase equil ibrium assuming composition independent fugacity- or activity-coeffici ents is described. The phase distribution calculation is formulated as a minimization problem and permits automatic and efficient handling o f an arbitary number of pure phases. An extension to reacting mixtures is given, the result being a minimization problem with a number of in dependent variables equal to the sum of the number of independent reac tions and the number of nonpure phases.
