General Description

By enabling a Makeup (MU) Block within a unit, the user may add flow to the unit in a controlled fashion. There are a number of advantages to using a MU block to add material to a unit:

  1. The user needs to add and configure only a single Makeup Source to feed many different units in a project.
  2. Since the Source is not connected to the MU with a standard link, there is no need for multiple links to be constructed.
  3. The user may often be able to avoid using either a PID or General Controller to control the addition.
  4. The MU ensures that the unit always has the correct flow at each iteration, or step, and hence this prevents 'lags' that can be a problem with controlled flows in Dynamic projects.

The Makeup Block (MU) can be added to a number of models, such as the Tie, Tank, Feeder-Cross Page Connector, Pipe and many Mass Separation models.

Notes:

  • The MU block gets the flow from the Makeup Source, so this unit must be inserted before enabling the MU in a unit.

Adding Makeup to a Unit

Step 1: add 1 to 8 Makeup Blocks to a unit by typing in the required value.Step 2: select the required Makeup Source from the drop down list on the 'MU' tab.Step 3: Select the control method for the Makeup addition from the 'Model' drop down list.Makeup01.png
About this image

Step 1 - Enable Makeup

The Makeup Block is enabled in a unit when the user enters an integer between 1 and 8 for the number of Makeups in the unit's access window.

The user may enable more than one Makeup Block per unit, by entering 2, 3, etc. The unit will then have the appropriate number of Tabs: MU1, MU2, MU3, etc. The user must then configure the Makeup Block(s) by clicking on the MUX tab.

Notes:

  1. The Makeup Block is a sub-model which is evaluated sequentially. The user can change the order that the sub-models are solved using the drop down lists on the first tab page - Off, On-AutoSequence, On-Sequence1, On-Sequence2, etc.
  2. The AutoSequence option will evaluate the sub-models as follows:
    • 1st - Makeup;
    • 2nd - Reactions;
    • 3rd - Environmental Heat eXchange; and
    • 4th - VLEquilibrium.
  3. For example, a Makeup may be added either before or after a reaction block sub-model.
    • If the Makeup is a reactant then it must be added prior to the reaction block.
    • If the user wants to achieve a final concentration from the unit then the Makeup block should be the last sub-model.
    • Due to the sequential nature of the sub-models, Makeups can not be used to achieve a final concentration of a reactant.

Step 2 - Connect to a Makeup Source

The next step is to connect the Makeup Block to a Makeup Source. Go to the MU tab and select the Makeup Source from a drop down list of available Makeup sources in the project.

Once a valid Makeup Source has been entered into the MakeupSrc field, a graphics symbol for the DirectLink will be displayed indicating that the unit has additional input. (Note: The user may change the name of this DirectLink or its graphical symbol in exactly the same way as for any other unit in SysCAD).

Step 3 - Configure the Makeup Block

The Makeup Block may then be configured as:

Each of the different options that can be configured are described in the table below.

Data Section

The default access window (MU) and variable names are described in detail in the following tables. These variables change as the user selects the various options that are available. Individual tables are shown for each Makeup Model, except for the Common Requirements and Common Results tables that show fields that are common to all methods.

Fixed Makeup Model

Tag/Symbol Input/Calc Description
Reqd.Basis MassFlow The user specifies the Makeup amount as a mass flowrate.
VolumeFlow The user specifies the Makeup amount as a volumetric flowrate at temperature.
VolumeFlow25 The user specifies the Makeup amount as a volumetric flowrate at 25°C.
NVolumeFlow The user specifies the Makeup amount as a volumetric flowrate at Normal Temperature.
MoleFlow The user specifies the Makeup amount as a molar flowrate.
MakeUp Measurement
Selection All The amount of material added is based on the Total makeup stream.
Phase The user can select the different phases to be included in the specified amount. For example, if the make up source has 50% solids and 50% liquids, and the user wants to specify a mass flow of 10t/h of solids, then only leave the solids tick box checked and SysCAD will add to the MUx block enough makeup to give 10t/h solids. In this case, a total of 20t/h will be added.
IndividualPhase As per Phase, the user is allowed to select the individual phase to be included in the specified amount. For example, if user wants to specify the organic addition - individual phase (or) to be 10t/h then select the (or) individual phase, and the makeup block will add enough to give 10t/h organic.

Note: To do so, user must have defined (or) phase in the species database and the makeup source must contain organics as part of its composition.

All Species/Species The user may select individual species to be included in the specified amount.
  • Select required species from the list.
  • Multiple selections are allowed. Up to 20 species can be selected.
Solid Species Only available in Build 138 or later. The user may select individual solid species to be included in the specified amount. Up to 20 solid species can be selected.

Vapour Species Only available in Build 138 or later. The user may select individual vapour species to be included in the specified amount. Up to 20 vapour species can be selected.
Component As per species above. The difference between species and component is that species is phase based, while a component is phase independent. For example, if NaCl is defined in the (aq) and (s) phases, and user wishes to select the solid phase only, then use the Species option and choose NaCl(s). If user wants to include both phases, then use the Component option and choose NaCl.
Element The user may select individual elements to be included in the specified amount.
If Phase/Individual Phase is selected:
For each phase Tickbox Select phase/s required.
If All Species/Species, Solid Species, Liquid Species, Vapour Species, Component or Element is selected all species/components/elements added will be displayed here.

There will usually be one extra to allow another species, component or element to be added - to a maximum of 20. To remove a species, component or element, choose the “-” option instead of the selected species, component or element.
