Abstract

A new multicomponent solid—liquid phase equilibrium calculation algorithm is described. The algorithm has the following features: (1) the phase selection procedure is easy (no stability test is needed); (2) the Gibbs phase rule is guaranteed; and (3) the mathematical procedures have thermodynamic meanings. Numerical examples for NaClKClMgCl2CaCl2H2O quinary system and its quaternary subsystems illustrate the capability of this algorithm. The comparison between this algorithm and the SQP (sequential quadratic programming) method for NaClKClMgCl2H2O system at 298.15 K and 273.15 K demonstrates the advantage of the new algorithm ovre SQP method.
