Thanks for your answer. I will try to add an equilibrium reaction. Could you please tell me, which property package from DWSIM is better for salts (NaCl, KCl MgCl2, MgSO4) crystalization? Thank you very much

I want to simulate a simple crystallisation of NaCl in DWSim. I use eNRTL as the thermodynamic property package and the components Water, Na+, Cl-. For eNRTL I chose SVLE in the tab Equilibrium Calculation Settings. Nevertheless, DWSim does not consider any solid phase. All Na+ and Cl- remain dissolved, although the concentration is well above the saturation of NaCl. How can I get DWSim to consider a solubility and calculate the solid-liquid-equilibrium for NaCl?
