I used a built in HYSYS sample file and then followed the following youtube video to get to the point I am in HYSYS: [login to view URL] In the video they were able to converge the column and produce LVGO and HVGO. I need my HYSYS file to converge like the video has it. The vacuum distillation part I would like done starts at moment 8:35 in the video. Attached is the HYSYS file I would like converged. Please explain how you were able to get this accomplished.
