=== Diagram ===

[[Image:TCEFlashTank.png]]

The diagram shows a drawing of the PHREEQC Flash Tank unit, with Feed, Product and Vapour streams. When the user inserts the PHREEQC Reactor unit into a flowsheet, a different graphics symbol can be selected from a pull down menu. The streams may be connected to any area of the drawing without affecting the actual connection point as SysCAD ignores the physical position of the connection.

== Inputs and Outputs ==

{{TCE Flash Tank Inputs Outputs|TCE =PHREEQC}}

== Behaviour when Model is OFF ==

If the user disables the unit, by un-ticking the ''On'' tick box, then the following actions occur:
* All material in streams connected to the 'Feed' will flow straight out of the 'Product' outlet, with no change in phase;
* No sub-models will be called.

So basically, the unit will be 'bypassed' without the user having to change any connections.

== Model Theory ==

{{TPS Unit Model Theory | TPS=PHREEQC | UnitOp=Flash Tank |OutputStream=aqueous solution | DBFile= PHREEQC database file (.dat)} | AllowSideCalc=No}}
*This model uses the VLE model of SysCAD, not PHREEQC, for calculating the vapour.  The liquid fraction of the stream is fed to PHREEQC to determine the ionic solution properties, which are then used in an iterative manner to calculate the BPE, and ultimately, the temperature, pressure, amount of vapour generated, etc.  Thus PHREEQC is used for calculating the liquid and solid fractions of the stream, and SysCAD VLE is used to calculate the vapour.
*The resulting mixture is then separated into vapour and product streams.

# '''[[VLE]]''' - Always on.
# '''[[#CFE tab page|CFE]]''' - Optional tab, only visible if the ''UseCFE'' option is enabled on the [[#TCE tab page|TCE]] tab page.
# '''[[#Bypass tab page|Bypass]]''' - Always on, with H2O(g) bypassed.
# '''[[#RxnBypass tab page|RxnBypass]]''' - Always shown.
# '''[[#PHREEQCResults tab page|PHREEQCResults]]''' tab - This tab displays the key results of the calculations.
# '''[[#Input tab page|Input]]''' tab - This tab displays a summary of the mapped Input stream as PHREEQC species.
# '''[[#Output tab page|Output]]''' tab - This tab displays the Output stream results including the amounts of each PHREEQC species present in the final mixture.
# '''[[#Diff tab page|Diff]]''' tab - Optional tab, only visible if the ''ShowRxnDiff'' option is enabled on the [[#TCE tab page|TCE]] tab page. This tab displays the amounts of each species which are formed or reacted as part of the calculations.

# '''[[Material Flow Section|QRxnBypass]]''' - Optional tab, only visible if ''ShowQRxnBypass'' is enabled on the [[#TCE tab page|TCE]] tab page.
# '''[[Material Flow Section|QFeed]]''' - Optional tab, only visible if ''ShowQFeed'' is enabled on the first tab page.
# '''[[Material Flow Section|QProd]]''' - Optional tab, only visible if ''ShowQProd'' is enabled on the first tab page.
# '''[[Common Data Sections#Common Data on Info Tab Page|Info]]''' tab - Contains general settings for the unit and allows the user to include documentation about the unit and create Hyperlinks to external documents.
# '''[[Links Table|Links]]''' tab, contains a summary table for all the input and output streams. 
# '''[[Audit]]''' tab - Contains summary information required for Mass and Energy balance. See [[Model Examples]] for enthalpy calculation Examples.
