Reactive distillation simulation related matters
Thread Content
Come in, I’m using Aspen to simulate a reactor with vapor separation functionality. Since a reactive distillation process is involved, I used the RedFAC model for simulation; however, this model requires at least two theoretical plates, whereas in reality the separation in the reactor corresponds to just one theoretical plate. How to solve it? I look forward to your advice.
With only one theoretical plate, the flash model has to be used; the original poster can try combining a reactor with Flash2
The poster can do this: first put the raw materials into a reactor; then use the reaction products as the feed for a flash tank
It’s better if LZ can be more specific, as that makes it easier to analyze. If a reactor is used in combination with FLASH, one issue that may arise is that the liquid produced by FLASH needs to be returned to the reactor, which requires a circulation loop.
How can that be reactive distillation? In that case, it’s not reactive distillation, right?
It is possible to consider specifying the plate efficiency, which would allow for an increase in the number of plates
