Hi GWB, I'm doing some simple charge balance type analyses in React. I've encountered an error where I can't bring in my NH3 data using the MINTEQ database. I set the basis species as NH4+, then try to set the units "as NH3 (aq)". That's when I get an error saying "Error: Don't know keyword: (aq)". It seems like it's having trouble interpreting the (aq) in the unit swap (?). Any suggestions on how to deal with this? Thanks, Clark
mfernandez posted a topic in The Geochemist's WorkbenchHi, 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!
