Hi. As l read down the paper l noticed their feed tray position was positioned differently as the optimized it. I then took for 30 stages, and put feed on tray number 9 and boom it converged. For 30 stages, and tray 15 (middle) used as a feed tray and with the same specifications, it doesn't converge. My question is, is there a way to tell that non convergence of a distillation column is due insufficient number of trays, or lower reflux ratio than the minimum or its just infeasible separation. if one knows then it will be easy to troubleshoot nonconvergence.
