- This video is about the simulation of the atmospheric distillation column in Aspen HYSYS. The major units of the process are:
1. Refluxed absorber
2. Side stripper
3. Pump arounds

The refinery process video playlist contains the simulation of refinery unit operations available in Aspen HYSYS. The data for these videos are collected from different sources and does not has any validity or authenticity. The purpose of videos is to teach the simulation method of these unit operations.
Was able to converge by adding refluex ratio spec at 1.3 and removing distillate rate spec, change btm temp to 320 and make 50th tray efficiency =1 ( all other efficiencies as mentioned in video). Once it is converged you can change the btm temp to 343.3 C as specified.
All the parameters are the same but the column cannot converge. I'm working in Hysys v12.0.
the simulation does not converge because the specified bottom temperature (343.3°C) is the feed temperature and you place it at the bottom. The solution for the simulation to converge is by placing the column specification temperature in tray #37, for a temperature of (320°C) and eliminating the distillate velocity specification by the reflux ratio to 1.3
Why not converge my absorber run??
It have taken long time, but it’s finally shown unconverged.
Why??
Olz Help
Try to manipulate define variables to make the column converge. Generally column converged in less than 50 iterations.
I have the same problem it doesn’t converge
I try to do this but it finally didn’t converge . I ve noticed that in the table of specification the colum « wt.Error» has values even when yours shows «empty»
I don’t understand please can you help me !!
How did you estimate the actual number of trays in this case? Is there a way to calculate case trays for distillation column in oil Refinery Process?
The explanation is nice, but I followed exactly as in the video, the column does not converge!!!However I was doing this in V11 ASPEN HYSYS
How many time need to converge it??
Hello brother, its a problem with excel sheet that have given to us ....
Its very good for us if you check it..
Could you give us the file please for this simulation ?
Or you can sent it to me by email? please 🙏🏼
