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 Flow section. Only available in Build 137 or later.

Solution Impurities
WaterMassFlow / WaterQm Calc The mass flow of pure water (H2O(l)) in the stream.
LiquidMassFlow / LQm Calc The mass flow of liquids in the stream.
AqueousMassFlow / AqQm Calc The mass flow of aqueous species (including H2O(l)) in the stream.
SlurryVolFlow / SLQv Calc The volume flow of slurry (liquids + solids) in the stream.
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.MassFlow / Liq.Imp.Qm Calc The mass flow of all liquid species excluding water, in the stream.
Liquid.Impurity.Frac / Liq.Imp.Frac Calc The mass fraction of all liquid species excluding water, in the stream.
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.MassFlow / Total.Imp.SLQm Calc The mass flow of all solid and liquid species excluding water, in the stream.
Total.Impurity.Frac / Total.Imp.Frac Calc The mass fraction of all solid and liquid species excluding water, in the stream.
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.MassFlow / AqImp.Qm Calc The mass flow of all aqueous species excluding water, in the stream.
AqImpurity.Frac / AqImp.Frac Calc The mass fraction of all aqueous species excluding water, in the stream.
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 Flow section.

NOTES:

  1. Many variables in the following section were added in Build137, for users using earlier builds, not all variables will be visible.
  2. In SysCAD 9.3 Build 137 and later, 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.
    • In region 5 (steam > 1073K), the IF97 values will be calculated using the IF97_2 equations (refer to Water and Steam Properties for more information.
H2OProps (Water and Steam Properties) ...
Water.VapourT@P Calc Water vapour temperature (boiling point/saturation temperature) at the stream pressure.
Water.State Calc SysCAD checks the stream properties with the steam tables and displays if under the stream 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 stream properties with the steam tables and displays:
If under the current stream 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.
