hi dear members

i'm simulating a process unit in hysys 8.8, in last section of my simulation i have distillation tower,

but!!!  when i put tower(distillation tower with reboiler and condenser ) , the following error appears:

  " not all components have Gibbs free energy data. Gibbbs reactor R-1001 will abort calculations. please refer to Trace window for a list of incomplete components."

 

so where is trace window???

 

note: i have to use distillation tower with both reboiler & condenser. when i use disstillation tower with just condenser, this error does not appear!!!!

 

can u help me please???

 

thanks.

You appear to have placed a Gibbs Reactor (which calculates outlet composition by minimizing Gibbs Free Energy).  This is not a distillation column.
