I would like to ask a teacher who is familiar with ASPEN
Thread Content
I’ve just started learning to use this software, and I really don’t understand the property-based approach at all; my understanding of such purely theoretical subjects was very limited when I studied at school. When it comes to software, I suddenly realize there are so many options to choose from; I don’t even know which of those few can be used for what. I would like to ask those teachers who are familiar with this subject: are there any commonly used methods in practice? Even after referring to Mr. Sun Lanyi’s textbook, I’m not quite clear about which method should be used in which situation. It just seems that in many situations, the choices are ambiguous.
What you said is also quite general. I’m learning on my own as well; I find some example problems online to practice with, in order to get familiar with the software and the methods related to material properties. There are only a few commonly used methods after all. To master it, go back and study thermodynamics, principles of chemical engineering, physical chemistry, and chemical engineering equipment first. . . Start reproducing*. Getting familiar is a process; don’t try to do too much. One chapter every two months, with regular reviews.
You can refer to Sun Lanyi’s “Aspen Plus Tutorial” (2nd edition); there is a table that classifies the selection of property methods, which you may find useful
Excuse me, Megatron, are those watches basically sufficient? I see there are many more methods than those watches offer
Just look at that watch. In fact, there are only a few property methods that are used frequently. Just check the scope of application. Or you can choose different physical property methods to see how large the deviation in the results is.
Commonly used: atmospheric pressure NRTL, electrochemical elecNRTL, pressure PR-BM – these are generally sufficient
I can repeat the course on chemical thermodynamics. . . Referring to Aspen’s built-in instructions makes it clear
Generally, those are the options to choose from; it’s not difficult at all
