Product Phases Specification
This window is used to specify the phases for all the product streams in unit operations from which product streams containing different phases can be drawn. The following unit operations have this feature and the Product Phases button is available in all of their main windows:
Compressor
Expander
Flash
Simple Heat Exchanger Hot and Cold Sides
Rigorous Heat Exchanger Hot and Cold Sides
LNG Heat Exchanger Individual Cells
Pipe
Valve
Stream Calculator - Overhead, Bottom and Pseudo Products
Conversion Reactor
Equilibrium Reactor
Plug Flow Reactor
Continuous Stirred Tank Reactor
Gibbs Reactor
ChemApp
Solid Fuel Combustion Reactor
The following is a list of all the possible phases that can be assigned to a product stream:
Vapor
Liquid
Solid
Decanted Water
Second (heavy) Liquid
Vapor + Liquid (Mixture)
PRO/II does not allow two product streams to have the same phase. Hence, if a phase is selected for a second time, the first selection is automatically deleted. Also, if Vapor + Liquid is selected as the phase for one stream, and either Liquid or Vapor is selected for another stream, the Vapor + Liquid entry is erased. You must then re-enter another acceptable phase for the first stream. The same is true for the reverse case.
If there are four product streams leaving a unit operation, the Vapor + Liquid phase option cannot be selected.
Usage
The Product Phases Window is displayed when the Product Phases button is pushed in one of the unit operation's windows.
This window contains a list of product streams leaving the unit operation as drawn in the simulation flowsheet. Select the desired phase condition(s) for the individual product streams from the drop down list. Phase condition can be designated for a maximum of four product streams.
