How  to  generate  a  Pvap-­‐T  diagram  in  HYSYS  v8.8  

• Open  HYSYS  • Start  Menu>All  Programs>AspenTech>Process  Modeling  V8.8>Aspen  HYSYS>Aspen  HYSYS  V8.8  

 

• Start  a  New  Case:  File>New>Case

• Pick  component(s)  

To  get  your  component  list,  hit  the  ADD  Button  and  it  will  take  you  to  the  component  selection  screen.  You  can  type  in  the  name  of  the  component  you  want  to  use  (e.g.,  cumene).

• Choose  a  suitable  fluid  Package

• Enter  the  Simulation  Environment  and  add  a  material  stream  

 

 

• Set  the  composition  as  a  single  pure  component  (100%  cumene)

• Go  to  “Flowsheet”  tab  on  the  ribbon  and  select  “Property  table”.

• Go  to  Design>Connections  and  select  “Vapor  fraction”  and  Temperature  as  two  independent  variables.  For  a  pure  component,  the  value  of  vapor  fraction  doesn’t  matter.  Select  the  temperature  range  you  need.

• Go  to  “Dependent  property”  (right  below  connections)  and  select  pressure  as  the  dependent  variable.

• Click  “Calculate”.  It  should  do  the  calulations.  You  can  see  the  table  and  plot  on  the  “Performance”  tab.

If  you  want  T-­‐xy,  P-­‐xy  or  x-­‐y  diagrams  for  binary  mixtures.  

 

First  go  back  to  your  component  list,  add  another  component,  go  to  simulation  environment  and  change  the  composition  of  the  material  stream.

Go  to  your  unit  operations  palette,  select  “Custom”  and  select  “Equilibrium  unit  operations”.

Double  click  on  the  symbol  of  the  Equilibrium  unit  operations”  and  add  you  will  have  the  options  to  see  the  plots.
