Introduction

This section is used to display material flow and all the associated properties. For example there will be a Qi and Qo section in a Pipe; QFeed and QProd in many of the unit operations; Split and Vented in an Area Model; or Qo in a DirectLink.

This model primarily has read only variables, and a few options that affect how information (or views) are displayed. The species model that is used will affect the display and may result in some extra fields or tab pages. The default 'Standard' species model will be described here.

Content Buttons

These buttons are only available in SysCAD 9.3.

Description

The SpModel.Reqd field is only shown if more than one Species Model is available in the project (eg. Standard and Bayer3). On a Qi, QFeed or QProd page, it is an input field, on a Qo page, it is a result field. The Species Model should only be explicitly chosen when a change in Species Model is required. In most cases SpModel.Reqd should simply be set to Inherit.

SpModel.Reqd Inherit Upstream configuration will be used.
Standard All the variables are calculated using the Mass Weighted Mean of the species.
Species Model Use an alternative species model, such as 'Bayer3' or 'Potash'.
SpModel.Used Standard The Standard species model is being used.
Species Model An alternative species model is being used.
SpModelType Display This field displays the Species Model type (or Name) used.
SpMdlIdNo Display This field displays a unique number generated when the Species Model is created.
ShowHeatingValues Tickbox If ticked, then Heating Values will be shown for the current stream.

These options are only available as specified in the model's configuration file.

SolubleSpecies1.Sat Calc This will be the saturation mass fraction of the soluble species. The tag is based on the actual species, for example NaCl.Sat. When .Act equals .Sat the mixture is saturated.

Description

Saturation...
Component List Any component that has the correct Vp Equations defined in the species database maybe selected here. See VLE sub section for more information.
VapourFrac / Vf Calc Only available in Build 137 or later. Displays the vapour mass fraction.
TotalP Calc Displays the total pressure.
PartialP Calc Displays the partial pressure based on the component selected.
SatP@T Calc Saturated pressure at the mixture temperature.

SatT@P Calc Saturated temperature at the mixture pressure.
WaterSatT@P Calc Displays the Saturation Temperature at pressure based on pure water. This is used to calculate the Boiling point elevation. (Please see Water and Steam Properties for further information on this calculation)
BPE Calc 1. Standard Species Model
a) If the stream is using the Standard Species model then please see Boiling Point Elevation for more information on this calculation.
b) The user may enter values for the van't Hoff constant for each aqueous species in the Species Database.
c) The user may set the method of calculating the BPE in all streams containing the Standard Species model as either None or van't Hoff in the Plant Model - Standard Properties Model Options.
2. Other Species Models, e.g. Bayer
a) Streams containing other species models, such as the Alumina 3 Bayer Species Model, will always use the implemented BPE equation to calculate this value.
b) The boiling point elevation is calculated as StreamSatT@P - ComponentSatT@P.
The Solvent used for this calculation is water.
Temperature / T Calc Temperature of the stream.

LatHtVap Calc The Latent heat of vaporisation of the listed component at the temperature and partial pressure of the vaporizing species at the local conditions. The latent heat is the difference in enthalpy between the vapour phase and the liquid phase of the species. This is calculated as Enthalpy(VapourPhase at local Temperature and Partial Pressure) - Enthalpy(Liquid Phase at T and Total Pressure). This is the enthalpy difference used in energy calculations. NB unless the partial pressure of the vaporizing species is equal to the saturation pressure, the latent heat may not have exactly the same value as for saturation conditions since the vapor phase enthalpy depends on its partial pressure.
LatHtVap@SatP Calc The Latent heat of vaporisation of the listed component at the temperature and saturation pressure of the vaporizing species corresponding to the local temperature. The latent heat is the difference in enthalpy between the vapour phase and the liquid phase of the species. This is calculated as Enthalpy(VapourPhase at Temperature, T and saturation pressure for that T, PSat(T)) - Enthalpy(Liquid Phase at T and Total Pressure). This is the latent heat that would be found in saturation tables for a given temperature.
RelHumidity Calc The relative humidity of the stream. This is only useful if the stream contains gases, such as O2, N2, Air, etc.

Relative Humidity = Partial Pressure of the Saturation Component (usually H2O) / Saturation Pressure of the Saturation Component at Stream Temperature * 100
Please see the YouTube link for a video presentation on setting up a feeder with the required Relative Humidity.

Acidity (pH)

These values are calculated based on the Ka and Kb values for acids and bases that are defined in the species database. It does not take buffering into account, and hence is, at best, an estimate of the pH.

SysCAD does have default Ka and Kb values defined for some acids and bases, and the user may enter values for other compounds. For a description of the method that SysCAD uses to calculate the acidity values see Acidity Calculations.

These values will only be shown if the user has chosen to display the pH_Estimate variables on the Plant Model - Views tab page or from the Include Properties dropdown list on the first page of the material flow section.

These values are calculated based on the species charges that are defined in the species database.

SteamViscosity Calc This field is only shown in SysCAD 9.2 Build 133 or later. The viscosity of pure steam at the stream temperature and pressure as calculated by IF97.

Heating Values

The Heating Value is the Heat of Combustion (ie. heat released, enthalpy change) if the stream components undergo complete combustion with oxygen to produce carbon dioxide gas and water. The higher heating value (Hi) (or Gross Calorific Value) is calculated by assuming that the water produced is liquid water. The lower heating value (Lo) (or Net Calorific Value) is calculated by assuming that the water is produced as steam.

NOTE: The Heating Value is only calculated for components which contain only carbon (eg. carbon solid), only hydrogen (eg. hydrogen gas) or only carbon and hydrogen (ie. a hydrocarbon, eg. methane (CH4)). Components which contain only carbon and oxygen (eg. carbon monoxide) and only carbon, hydrogen and oxygen (eg. ethanol) are also included.

These heating values will only be shown if the user has chosen to display Heating Values using the ShowHeatingValues tickbox.

  • 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 (OK 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.
