Which tower model in Aspen Plus can be used to simulate a real-world spray tower?
Reply to 2# liwenfei506: Could you please explain in detail which model from the tower model is being used? Thank you! I used radfrac before, but found that it has only one feed stream; what I need to simulate is a system with two feed streams and two output streams. Later, extrac was used, and an error occurred during the final calculation.
It is the RADfrac model that is used. This model can simulate distillation, absorption, and desorption processes. You mentioned that the feed can consist of n streams, with at least one stream; if you don’t believe it, try connecting them again. Also, don’t try to use the radfrac model right from the start; get familiar with it first! Then when you encounter many problems, you’ll understand. On the forum, find a tutorial from Zhejiang University and follow it; by learning the basic things through that, you’ll understand it.
Reply to 4#: I’m also straightforward. Thanks for the advice!
Has the original poster solved the problem? I also want to ask how to simulate a spray tower
