This post was last edited by Roupang on 2019-3-11 08:07. Hello everyone, I am currently working on a distillation tower, and in order to determine the composition of the materials in various pipelines, I used the simulation provided in the attachment. When entering the parameters for the tower, the fields listed in the attached table remain red and do not show as completed. What could be the reason for this, and how can it be resolved? Since I have not been using Aspen for long, there are many issues in the attachment; I hope everyone can offer their guidance. Thank you very much

It won’t open; I’m not sure exactly what’s wrong

Change Above-stage to on-stage

In the product stream, it must be ensured that the overhead draw in the process simulation is the stream that follows the gas-phase draw, not the liquid phase. Because there is vapor on H1.
