aspen simulated caustic scrubber tower
Thread Content
May I ask how to simulate the alkaline scrubber used for absorbing CO2 in methanol-to-olefins using Aspen? Or rather, what property equations or design parameters do you use for simulation? It is the simulation of this alkali scrubber that we have not been able to develop yet; it took a long time. I’m a beginner, and my language skills aren’t perfect; I hope you can understand what I mean. Could you help me? Thanks!
Personally, I think the redfrace model should be used as an absorb model, with an electrolyte model employed
Reply to 2# fkexue: Can you be more detailed? I tried doing it for a few days, but it still didn’t come out~~
Reply to 3# fighting21: I’m also a beginner; I just saw some information that said so. I haven’t done it yet.
Absorption towers are already difficult to work with, especially chemical absorption towers. For thermodynamic approaches, an electrolyte model is used; you can set up the electrolyte equilibrium reactions in Elec Wizard, and then change the absorber option to YES in the convergence settings. Additionally, the amount of absorbent must also be appropriate.
The alkali scrubber may involve pumparound recirculation, which can address the issue of mass non-conservation
Hello, may I ask you some questions regarding the simulation of alkali scrubbers? Thank you so much
