Abstract

A new hybrid electrolyte VLE model is suggested. By extending the theoretical Debye-Hückel-Pitzer expression with the empirical Redlich-Kister term, a highly flexible model has been developed which is well suited for representing VLE behavior for specific systems. The system H2O-HCl-MgCl2 is accurately described in a temperature and concentration range of 273423 K, 030 mole% HCl and 012 mole% MgCl2. 6 binary parameters (totally 11 when the temperature dependency is included) were used in the fit.
