Hello, i'm doing a project at university and I have to design a packed column. It's the TEG regenerator from the glycol dehydration unit, which is included in the gas dehydration system.
I've already determined all the process parameters but now I have to define the size of the column.
At first I started using the tool "Equipment design - Tray sizing" from Hysys V8.8 to obtain an estimate for the diamater and then use the KG tower software. From KG tower i got a diameter, but i couldn't get the HETP neither from KG nor hysys.
I define the packing type in hysys, but i have to define the HETP too, which is what i want to get from the software.
In addition, the software shows the following 2 warnings:
"Section_1 - X is out of range for the SLE correlation"
"Section_1 - Pressure drop is out of range for the SLE correlation"
I've tried to get rid of them, changinf de pressure drop/m but nothing happened.
X is defined as the Sectional Area [m2], which depends on the section diameter, which I didn't define.
I'm using the mode:design, not rating
I've also selected different correlations, instead of SLE, but there's always a problem with the pressure drop.
Thank you in advance
