Hello, I am using the Standard Edition and I compiled my database including Pitzer coefficients as I am using high saline conditions, up to saturation for NaCl and MgCl2. I wanted to draw a stability diagram for Iron in Act2 but it only allows the Debye Model and doesnt load the database using the HMV model. I saw this also in manual that act 2 doesnt support pitzer, meaning I cant use act2 to draw the stability diagram for iron in MgCl2. my question is: are there any other tools which I could use, using the HMV model to obtain the stability diagram. Many Thanks, Nikoleta

Hi, I am interested in using GWB to model CO2-NH3-H2O vapor-liquid equilibria using Pitzer coefficients. Using thermo_phrqpitz.dat, this doesn't seem to be possible. Is their another data set that would allow me to do this? If not, would it be possible to edit one of the data sets in such a way to make this possible. It's worth noting that I'd like to include the carbamate ion species (e.g. H2NCOO-). There was a recent publication in the International Journal of Greenhouse Gas Control published recently (Author: Yin Xu, Title: Modeling of the NH3-CO2-H2O vapor-liquid equilibria behavior with species-group Pitzer activity coefficient model), that I though might be useful in this task. If the vapor-side modeling is not feasible, there would still be value in just modeling the closed aqueous system. If anyone has any suggestions, please let me know. Thanks!
