Add species to the Basis pane. Use the Pitzer equations for calculations at high ionic strength.
Mineral saturation states calculated using the Debye-Huckel equation for activity coefficients. Field evidence suggests Halite and Anhydrite are in equilibrium with the fluid, in contrast to calculations.
File → Open → Thermo Data... A thermo dataset utilizing the Pitzer equations, developed for application to high ionic strength systems, may provide more accurate calculation of Mineral saturation in this example.
Select thermo_hmw.dat to calculate activities using the Pitzer equations.
Anhydrite and Halite appear very close to being in equilibrium, unlike results using the Debye-Huckel equation.
