Solution Impurities

This section will show impurity values. Most of these fields will only be shown if the user has chosen to display the SolutionImpurities in the Plant Model - Views tab page or from the Include Properties dropdown list on the first page of the material Content section.

Solution Impurities
WaterMass / WaterMt Calc The mass of pure water (H2O(l)) in the content.
LiquidMass / LMt Calc The mass of liquids in the content.
AqueousMass / AqMt Calc The mass of aqueous species (including H2O(l)) in the content.
SlurryVol / SLMt Calc The volume of slurry (liquids + solids) in the content.
TotalSuspendedSolids / TSS Calc The Total Suspended Solids (TSS) is the sum of all solids species, reported as a slurry (liquids + solids) concentration.
Liquid Impurity
Liquid.Impurity.Mass / Liq.Imp.Mt Calc The mass of all liquid species excluding water, in the content.
Liquid.Impurity.Frac / Liq.Imp.Frac Calc The mass fraction of all liquid species excluding water, in the content.
TotalDissolvedSolids / TDS Calc The Total Dissolved Solids (TDS) is the sum of all liquid species (not including water), reported as a liquid concentration.
Total.Impurity.Mass / Total.Imp.SLMt Calc The mass of all solid and liquid species excluding water, in the content.
Total.Impurity.Frac / Total.Imp.Frac Calc The mass fraction of all solid and liquid species excluding water, in the content.
Total.Impurity.Conc / Total.Imp.Conc Calc The sum of all solid and liquid species excluding water, reported as a slurry (liquids + solids) concentration.
Impurity Breakdown
AqImpurity.Mass / AqImp.Mt Calc The mass of all aqueous species excluding water, in the content.
AqImpurity.Frac / AqImp.Frac Calc The mass fraction of all aqueous species excluding water, in the content.
AqImpurity.Conc / AqImp.Conc Calc The sum of all aqueous species excluding water, reported as a liquid concentration.

H2O Properties

This section will show water/steam entropy values. These will only be shown if the user has chosen to display the H2OProperties in the Plant Model - Views tab page or from the Include Properties dropdown list on the first page of the material Content section.

NOTES:

  1. If the project is using IF97 for the properties of steam and water then:
    • The enthalpies will only be slightly different to the IF97 values shown here due to the slightly different reference temperature (0°C vs 0.01°C).
    • The entropies will be different to the IF97 values by a fixed amount due to the different reference temperatures (0 Kelvin vs 0.01°C).
    • The densities will be the same.
H2OProps (Water and Steam Properties) ...
Water.VapourT@P Calc Water vapour temperature (boiling point/saturation temperature) at the content pressure.
Water.State Calc SysCAD checks the stream properties with the steam tables and displays if under the content temperature and pressure, would all the H2O be liquid (water). If yes, it will display OK, if not it will display Invalid.
Water.Enthalpy / H Calc Water enthalpy (based on reference point of 0°C).
Water.IF97.Enthalpy / H Calc Water enthalpy calculated from IF97 (based on reference point of triple point of water (0.01°C)).
Water.Entropy / S Calc Water entropy (based on reference point of absolute zero (0K)).
Water.IF97.Entropy / S Calc Water entropy calculated from IF97 (based on reference point of triple point of water (0.01°C)).
Water.Density / Rho Calc Water density.
Water.IF97.Density / Rho Calc Water density calculated from IF97.
Steam.State Calc SysCAD checks the content properties with the steam tables and displays:
If under the current content temperature and pressure, would all the H2O be vapour (steam). If yes, it will display OK, if not it will display Invalid.
Steam.Enthalpy / H Calc Steam enthalpy (based on reference point of 0°C).
Steam.IF97.Enthalpy / H Calc Steam enthalpy calculated from IF97 (based on reference point of triple point of water (0.01°C)).
Steam.Entropy / S Calc Steam entropy (based on reference point of absolute zero (0K)).
Steam.IF97.Entropy / S Calc Steam entropy calculated from IF97 (based on reference point of triple point of water (0.01°C)).
Steam.Density / Rho Calc Steam density.
Steam.IF97.Density / Rho Calc Steam density calculated from IF97.
