Mist entrainment in the absorption tower
Thread Content
Hello, everyone! Due to the phenomenon of foam entrainment in actual production, it is difficult for the results obtained from ASPEN simulations of absorption towers to match the actual production data. I would like to ask how to take into account the impact of foam entrainment in these simulations, so as to make the calculated results as close as possible to the actual data?
Check the relevant settings for the absorption module; there seem to be settings related to entrainment and flooding
Take a look at the relevant settings for the absorption module; there seem to be settings related to entrainment and flooding, etc. Posted by din*ang on 2009-11-5 15:39. Could you be more specific? I can’t find those settings anywhere
If the RADFRAC module is used, there are settings for flooding and foaming in the design and calculation of trays/packs; for packed absorption towers, these settings should be found under Pack sizing/rating
For RAD Frac, under the Efficiency section and within the OPTIONS option, select EFFICIENCY TYPE and METHOD, and then enter the efficiency level based on your experience.
For absorption towers and stripping towers, the required efficiency is generally low; a value of 0.2–0.5 is sufficient. The opening ratio can be increased as well as the tower diameter, but the kinetic energy factor should not be too high
Hello, I would like to ask how to set it up for the RateFrac module? It would be great if you could be more specific; I’m a complete beginner. Thank you very much! 5# Albertlu
