\"One Question per Day\" in the ASPEN Technical Exchange Area”
Thread Content
I noticed that many sections on the forum have a \"Question of the Day\" feature, and users are very enthusiastic about participating. By pooling ideas and discussing problems together, it is easier to improve one’s skills and expand one’s knowledge. Therefore, I suggest that similar activities be carried out in the ASPEN technology exchange area as well, so that everyone can learn together*
Push it yourself: time:
:)Support, support! I have so many questions: lol
spport!!!!!!!!!!!
Let me offer some initial thoughts: lol To simulate liquid-liquid separation using Decanter, if there are solids present in the liquid, those solids do not participate in the separation process; they remain in the lower layer of solution simply because of their higher density. What’s the best way to handle this? For example: H2O, C6H6, and Fe2O3. I gave it a try, but it seems impossible to simulate this properly; the iron oxide is dispersed in two phases. . .
I would appreciate it if an expert could explain the issue raised on floor 6; I’m facing the same problem. The density values of the two phases in the simulated results are incorrect, and I really don’t understand how to resolve this issue.
There are actually many types of problems with ASPEN, and they arise every time. Personally, I think it’s just a software, and software-related issues are easy to resolve. However, the problems with ASPEN are more related to the way of programming, and this might well be what truly counts as the skill of chemical engineers. So, it’s hard to say whether such questions can get answers from experts~
Support! I hope the forum will keep getting better!
I think it can be understood in this way: an effluent concentrator is suitable only for liquid-liquid equilibrium; if solids are involved, it can be considered that the model chosen is inappropriate. Moreover, it doesn’t seem to be practiced this way in actual operations. In the case of solid electrolytes, things are much simpler, as they can be distributed directly between two liquid phases. But for water-insoluble solids, I think one should first use a solid model to separate them out and then proceed with extraction……
Good suggestion; more basic things
I have a question. I’m working on a problem related to azeotropic distillation, and I plan to use a rigorous distillation model for the calculations; however, it’s not possible to determine in advance the number of trays and the feed tray. How can the number of trays and the feed tray for an azeotropic process be calculated using phase diagrams? Or are there other ways to determine it?
It’s a good idea. It is very effective in improving ASPEN
