The limits are thermodynamic framework dependent. There are three frameworks available in OLI Software. MSE (default in version 11.5), MSE-SRK, and AQ.
For MSE the ranges are:
- Temperature: Up to 0.9* Tcritical. For a water-rich solution this would be approximately 340 oC
- Pressure: 1500 Atmospheres
- Ionic Strength: No limit
- TDS: No Limit
- Concentration: infinite dilution to fused salt.
For MSE-SRK the ranges are:
Essentially the same as for MSE but targeted at a smaller set of chemistries. In the water-rich liquid phase the ranges are the same.
In the non-water-rich phases (including vapor), CO2 and/or H2S rich in light hydrocarbons – C1 to C7 and pressures greater than 80 Atm. I do have a wiki for this: https://wiki.olisystems.com/wiki/MSE-SRK
For AQ the ranges are:
The older AQ thermodynamic framework is much more limited.
- Temperature: 0 oC to 300 oC
- Pressure: 1500 Atmospheres
- Ionic Strength: 30 mol/Kg H2O
