DETERMINATION OF EQUILIBRIUM STATES IN MULTIPHASE SYSTEMS

Volume corrections in calculation of equilibrium state for multi-phase systems, as an extension from one-phase systems, have been described. The algorithms can handle with one, two, three or more phases of diff erent volumes. Several applications of the algorithms to calculation o f equilibrium concentrations of all species in two- and three-phase sy stems have been presented. Different possibilities of the determinatio n of equilibrium constants from extraction data have been discussed. ( C) 1997 Elsevier Science B.V.
