----- Forwarded by Michele Y Crouse/WRD/USGS/DOI on 10/02/01 11:57 a.m. ----- "Gamble, S. - Carlsbad R & D" To: h2osoft@xxxxxxxx <sagamble@xxxxxx cc: bal.com> Subject: Use of Programming for Aqueous GeoChemical Modeling/Phreeqc 10/02/01 11:15 a.m. Sir, I have a need to learn and apply phase chemistry and mass balances to the system K, Mg, Na, Cl, SO4, H2O at various temperatures and various % Saturation's for KCl & NaCl. This includes evaporation schemes to recover salts from brines. At weaker concentrations I may need to be concerned with Ca, but most of the work will be done at concentrations where Ca is essentially insoluble. I have experience in simple systems like K-Na-Cl-H2O but the above complex system I have difficulty with. With my limited knowledge I believe the fields I will have interested in will be glaserite(aphthitalite), schoenite(picromerite), leonite, kainite, and carnallite in addition to the KCl and NaCl. Will Web-Phreeqc or another commercial version do this work?
