==Introduction==

Makeup Blocks can be used as a quick and efficient means to control species or elemental concentration, instead of using a PID or General Controller.

==Why==

Using a Makeup Block to control the concentration of a species or element in a unit is quick and easy to configure and will improve solution convergence and speed.

==How==
To configure elemental concentration control in a unit using a Makeup Block:
* Add a [[Makeup_Source|Makeup Source]] to the flowsheet with the required species composition.
* Add a Makeup Block to the required unit, refer to [[Makeup_Block_(MU)#Adding_Makeup_to_a_Unit|'Adding a Makeup Block to a Unit']].
* Select up the required [[Makeup_Source|Makeup Source]].
* Select Model = 'Product Concentration'.
* For 'Product Mass Measurement' select 'Element'.
* Choose the required element from the drop down list.
* Select 'Product Volume Measurement' = 'Phase'.
* Tick 'Liquids'.
* Enter the required product concentration.

==Did you know==

* The user only needs to add and configure a single Makeup Source to feed many different units in a project.
* Since the Source is not connected to the Makeup Blocks with a standard links, there is no need for multiple links to be constructed.

==Example==

The pictures below show an example of using water addition to dilute the Nickel concentration to 75 g/L.
