Question from a beginner: What are the differences between HYSYS, ASPEN, and PROⅡ?
Thread Content
I also want to learn one, but I’m not sure which one is more useful. Are they basically all useful in general? Thank you!
I’m just starting to learn PRO2; I’m a beginner. I heard from experienced users that PRO2 is easy to get started with, and its interface is quite user-friendly
I can use all three; each has its advantages and disadvantages. I personally prefer to start with HYSYS; for chemical and electrolyte systems, I use Aspen Plus for further verification, and for petroleum product properties, I use ProII for confirmation.
I think all three software options are good, and their functions aren’t very different; it’s just that they have different focuses. For beginners, it’s better to start with *proII, as it’s relatively easier to use, with a simple interface and straightforward operations. However, I personally prefer Aspen, as it converges relatively quickly – you can tell whether convergence has occurred after just one run – and it also offers a wide range of models.
