Simulation of two sections of the Aspen distillation column
Thread Content
The two sections of the Aspen packed distillation column have different diameters and different packing; how to simulate this?
When combining two columns, you can choose columns without a reboiler or without a condenser
This has nothing to do with hydraulics; it’s not related to material balance, right?
The second floor offers ideas for solving problems – are there any better methods?
It seems that this is the only way to do it. You can refer to the ASPEN simulation for partition wall distillation
It can be set in a single RADFRAC (rating mode)
Some experts say: Create 2 new entries in Packing Sizing, and then enter your tower diameter and packing details respectively, and that’s it. Is this okay?
It doesn’t matter at all if hydraulic calculations are not performed; the tray efficiency for this section might just be set differently.
