== Inputs and Outputs ==

{{Evaporator Input and Output}}

== 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' and 'Recycle' inlets will flow straight out of the 'Product' outlet, with no change in phase or energy exchange with material flowing through the internal heat exchanger;
* All material in streams connected to the 'Embedded HX Shell' connections will have no change in phase or energy exchange with material flowing through the Evaporator;
* No sub-models will be called.

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

== Hints and Comments ==

# The information in the [[Vapour Liquid Equilibrium (VLE)|VLE Section]] must be correct for the Evaporator to operate as required. If the VLE configuration requires information that is not available, then the flashing will not occur.
# PHREEQC uses the SysCAD VLE submodel to perform flashing.  Vapour-Liquid Equilibrium is not directly calculated by PHREEQC.
