webmaster Posted November 8, 2004 Share Posted November 8, 2004 From: Paul Foellbach Subject: ANHYDRITE - dataset change I attempt to model the Stability of Anhydrite at 200 bars between 0 and 300 °C.I calculated the log Ks of the reaction ANHYDRITE= Ca++ + SO4— with SUPCRT92 for the Temperatures 0-300 at 200 bars. I replaced the LogKs of the thermo-dataset-reaction of Anhydrite in the data section MINERALS (written with BASIS species) with the SUPCRT-calculated logKs. Here's the script for REACT: Read data for 646 aqueous species, 625 minerals, and 10 gases. > temperature initial = 0, final = 300 > 1 kg free H2O > balance on Ca++ > total molality SO4-- = .028 It is not running. I have to close REACT because of a specific error. From: William F. McKenzie Subject: Re: ANHYDRITE - dataset change Try the following (T initial = 0.01): React> react 500 mg Anhydrite React> temperature initial = .01, final = 300 React> balance on Ca++ React> total molality SO4-- = .028 React> go Quote Link to comment Share on other sites More sharing options...
