Doubts about the absorption process simulation in Aspen distillation columns
Thread Content
Based on an absorption example in the Aspen book, it is necessary to select “yes” in the “absorber” field of the “radfrac” module. What is the difference between selecting “yes” and “no” for this “absorber”? I found that in some cases, selecting “no” in the “absorber” field is still sufficient to carry out the absorption calculation
Different mathematical calculation models are chosen; if it’s yes, then that model is more suitable for absorption, and it’s fine as long as it can converge if it’s no
Choosing yes is to make the process converge more easily
