  1. Hi Tom, i have a situaton where i'm bubling a CO2 rich gas (attached)in a saturated lime soln to achive final pH of 9.0 (tank open to atmosphere). What is the resulting chemistry at the end of the reaction? CO2 rich Gas Composition (mol %) Hydrogen H2 1.09 Methane CH4 5.42 Carbon monoxide CO 4.86 Nitrogen N2 0.64 Ethylene C2H4 0.55 Ethane C2H6 0.8 Oxygen/Argon O2/Ar 0.28 Propylene C3H6 0.67 Carbon dioxide CO2 84.45 Propane +butene 0.5 water pH 12 Ca (mg/L) 209 Mg (mg/L) 0.1 Na (mg/L) 301.5 K (mg/L) 47 NH3-N (mg/L) 7.2 Cl (mg/L) 367 SO4 (mg/L) 177 F (mg/L) 1.6 M-Alkalinity (mg/L as CaCO3) 545 P-Alkalinity (mg/L as CaCO3) 489 HCO3- (mg/L as CaCO3) 0 CO3-- (mg/L as CaCO3) 115 OH (mg/L as CaCO3) 602 Conductivity (┬ÁS/cm) 3411.5
  2. electrical conductivity and TDS

    Hi Tom, files attached for both cases. Raection with H2SO4.rea Reaction with CO2.rea
  3. electrical conductivity and TDS

    Qouvadis Thickenr overflow data.gssHi 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
  4. electrical conductivity and TDS

    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,
  5. React: charge balance error!

    its version 8.0 I subsequently upgraded to 8.0.5 with the patch but the problem persist!
  6. Hi, I have a problem when using React and Spec8. When i enter the data on the basis and exclude alkalinity the % ion balance error is low ~ 13%.whe plotting this data on Gplot the data is skewed towards the cations !Howver, when I include the alkalinity the error increases to 90% with the plotted data balancing. Is there anything that that i'm doing wrong? Thickner outflow .rea
