Mooketsi Posted October 11, 2010 Share Posted October 11, 2010 Hi i'm modeling a Ca-OH water type system recating it with CO2 and on another case with H2SO4. With CO2 the graphs on REACT correlates when plotting dissolved solids or EC versus CO2 reacted. However, when plotting the same using sulphuric acid it does not. what could be the problem? regards, Quote Link to comment Share on other sites More sharing options...
Tom Meuzelaar Posted October 11, 2010 Share Posted October 11, 2010 Hi Mooketsi: Hard to tell without being able to look at your scripts. Can you attach the CO2 and HSO4 model scripts, any custom databases, and a quick summary of what behavior you expect in both cases? Regards, Tom Meuzelaar RockWare, Inc.

Mooketsi Posted October 12, 2010 Author Share Posted October 12, 2010 Hi Tom, Thanks for your reply. I have attached the GSS file. I modelled two scenarios allowing for pptn. 1) Reacted with 2 g CO2(g) and 2) reacted with 2.5 g H2SO4. In scenario 1 the conductivity vs CO2 added correlates with TDS vs CO2 added. However, in scenario 2 it is not the case. This is what i'm investigating. regards Quote Link to comment Share on other sites More sharing options...
Tom Meuzelaar Posted October 12, 2010 Share Posted October 12, 2010 Hi Mooketsi: I have your GSS file. Can you attach the React files as well? Regards, Tom Meuzelaar RockWare, Inc. Quote Link to comment Share on other sites More sharing options...
Mooketsi Posted October 12, 2010 Author Share Posted October 12, 2010 Hi Tom, files attached for both cases. Quote Link to comment Share on other sites More sharing options...
Tom Meuzelaar Posted October 12, 2010 Share Posted October 12, 2010 Thanks Mooketsi: For your H2SO4 run, TDS appears to increase with H2SO4 reacted. Electrical conductivity, however, follows the concentration of the OH- anions and H+ cations, which have stronger conductance values than the major anions and cations. Refer to Standard Methods 2510A for further information. I hope that helps, Tom Quote Link to comment Share on other sites More sharing options...
