NaClFluidProperties
Fluid properties for NaCl
NaCl fluid properties as a function of pressure (Pa) and temperature (K).
Only solid state (halite) properties are currently implemented to use in brine formulation
Properties for halite given by Driesner (2007), apart from thermal conductivity, which is calculated using the data of Urqhart and Bauer (2015). Critical values are taken from Anderko and Pitzer (1992).
Properties of NaCl
| Property | value | 
|---|---|
| Molar mass | 0.058443 kg/mol | 
| Critical temperature | 3841.15 K | 
| Critical pressure | 18.2 MPa | 
| Critical density | 108.43 kg/m | 
| Triple point temperature | 1073.85 K | 
| Triple point pressure | 50 Pa | 
Range of validity
The NaClFluidProperties UserObject is valid for the solid phase region only
