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.
