Introduction

This section is used to display material content and all the associated properties. For example there will be a Content and M section in a Tank - Dynamic Mode.

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 Tab Page

Tag (Long/Short) Input / Calc Description/Calculated Variables / Options
Include Properties Button.png

Displays a list of properties that the user can view or hide by clicking on the required property.
Energy Fields related to Thermodynamic properties, e.g. Hz, Hs, Cp, etc.
Saturation Fields related to the properties of the default Saturation species (usually H2O).
pH_Estimate Fields related to the pH estimate
Charge Fields related to Charge
Transport Transport properties such as viscosity and thermal conductivity
DensityCorrections Additional density correction variables
HeatsOfCombustion The Heat of Combustion is the heat released (ie. enthalpy change) if the stream components undergo complete combustion with oxygen to produce carbon dioxide gas and water.
Only available in Build 139 or later (replaces old Heating Values option).
ValuesAtUserTandP Additional variables will be evaluated at the user defined temperature and pressure
SolutionImpurities Impurity flows, fractions and concentrations.
H2OProperties Properties of pure water and steam
WaterQuality Properties of water streams such as hardness, alkalinity and oxygen demand
The following variables shows the species model that is used to calculate the physical properties of the contents, such as density, heat capacity, etc.
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 Only available in Build 138 or earlier. If ticked, then the calorific Heating Values of the material in the content will be displayed. For Build 139 or later, refer to Heats Of Combustion.

Qualities

Lockup.Action Input / Display The user may select Modify Content. The 'Lockup' values are set on the 'DLockup' tab.
The field displays the actual state of the Lock Up function: If this has been enabled then this will display 'Lockup.Action(On)', otherwise it will display 'Lockup.Action'. Please see LockUp for more information.
Note: Lockup must first be enabled on the Plant Model - Qualities Tab and created upstream of the surge unit before the user may modify it here.
MatTrack.Action Input / Display The user may select Modify Content. The 'Tracking' values are set on the 'DTrack' tab.
The field displays the actual state of the Material Tracking function: If this has been enabled then this will display 'MatTrack.Action(On)', otherwise it will display 'MatTrack.Action'. Please see Material Tracking for more information.
Note: Material Tracking must first be configured on the Plant Model - Qualities Tab and created upstream of the surge unit before the user may modify it here.
SzDist.Action Input / Display The user may select Modify Content. The 'Size Distribution' values are set on the 'DSz' tab.
The field displays the actual state of the Size Distribution function: If this has been enabled then this will display 'SzDist.Action(On)', otherwise it will display 'SzDist.Action'. Please see Size Distribution (PSD) for more information.
Note: Size Distribution must first be created upstream of the surge unit before the user may modify it here.
SzSSA.Action Input / Display The user may select Modify Content. The 'SSA' values are set on the 'SSA' tab.
The field displays the actual state of the SSA function: If this has been enabled then this will display 'SzSSA.Action(On)', otherwise it will display 'SzSSA.Action'. Please see Specific Surface Area (SSA) for more information.
Note: SSA must first be created upstream of the surge unit before the user may modify it here.
Lockup.InUse Display Displays the state of the LockUp function: Yes or No.
MatTrack.InUse Display Displays the state of the Material Tracking function: Yes or No.
SzDist.InUse Display Displays the state of the Size Distribution (PSD) function: Yes or No.
SzSSA.InUse Display Displays the state of the Specific Surface Area (SSA) function: Yes or No.
Properties
This section is shown in the Dynamic Tank model but not in the Multi-Storage model.
Temperature / T Input / Display This displays the temperature of the material contents. The user may also change the temperature here.
Pressure / P Display The pressure of the material contents.
Level / Lvl Input / Display This displays the level of the material contents. The user may also set the level in the unit here.
HiLevelLimit / HiLmt Input The highest allowable level of the unit. If the solids and liquids level rises above this value, the unit will give a warning. The default value is 102%, so if the user does not change this value, it will never give a warning.
LoLevelLimit / LoLmt Input The lowest allowable level of the unit. If the solids and liquids level drops below this value, the unit will give a warning. The default value is 0%, so if the user does not change this value, it will never give a warning.
LevelHi / LvlHi Display This is True (1) if the unit level is above the HiLevelLimit and False (0) otherwise.
LevelLo / LvlLo Display This is True (1) if the unit level is below the LoLevelLimit and False (0) otherwise.
LimitAsStatus TickBox If this is disabled then the warning messages for High and Low limits will not be displayed.
