How to remove warnings in Aspen simulation results
Thread Content
The Aspen simulation results come with warnings; it seems that the presence of co is the reason for phase separation, and the results continue to show warnings. Is there anyone who can help me take a look? Thank you very much, it’s urgent
There’s something wrong with the settings for b4, I think. Check what the result information is for b4
Hello, may I ask how to modify the result of B4, where CO is one of the components that appear in it?
You’re not speaking clearly. It is because the feed contains carbon monoxide, which was not completely converted in reactor B2; that’s why the stream entering distillation column B4 contains gaseous carbon monoxide The above are my guesses based on what you said
If that’s the case, try adding a flash unit between B4 and B2 to separate the gas and liquid phases, with the liquid phase going to B4 for distillation.
What version of the software is LZ using? It may not be able to open. Should the warning message be included?
For the separation of the various components in Tower B4, use molar fractions rather than absolute values; your values differ from these because they are based on decimal values. 13 Set the logistics pressure slightly higher than the tower operating pressure, for example, 1.1 bar
