Help me verify the hydraulic design of the ASPEN packed tower, experts! ! ! !
Thread Content
Firstly, such a filler is required, but by adjusting the tower diameter and the filler specifications (500Y), the hydraulic operation diagram and the tower’s hydraulic performance results are never correct. I’m seeking advice from experts! ! It’s been bothering me for months :( Below is a partial screenshot of the simulation I performed using Aspen
It is estimated that the vapor-liquid loads in the upper and lower sections of the tower differ significantly; therefore, the tower diameter should be designed differently, with a larger diameter for the lower section
It’s overflowing; it’s already over 200%. Reduce the liquid flow rate or increase the tower diameter, and replace it with 250Y packing
I tried it, but the liquid level dropped; meanwhile, the stripping section indicated that the bed pressure drop was too low, and a red warning appeared on the hydraulic operation diagram
If none of the above methods work. Consider changing the process conditions, such as the thermal state of the feed, the reflux rate, and the heating amount at the bottom of the tower, in order to match the vapor-liquid load in the upper and lower sections.
Thank you for your suggestion; I’ll give it a try
