3. Ph.D. Thesis by Kaj Thomsen. The thesis deals with aqueous electrolyte mixtures. The Extended UNIQUAC model is being used to describe the excess Gibbs energy of such solutions. Extended UNIQUAC parameters for the twelve ions Na⁺, K⁺, NH₄⁺, H⁺, Cl^-, NO₃^-, SO₄^2-, HSO₄^-, OH^-, CO₃^2-, HCO₃^-, and S₂O₈^2- are estimated. A computer program including a steady state process simulator for the design, simulation, and optimization of fractional crystallization processes is presented.
4. Document containing the relevant equations for activity coefficients, molar derivatives of activity coefficients, excess enthalpy, and excess heat capacity according to The Extended UNIQUAC model.
