The problem of ethanol azeotropy
Thread Content
Why doesn’t the ethanol component that emerges as an azeotrope at the top of my ASPEN distillation column reach the azeotrope concentration specified by ASPEN? There is always a difference of a few percentage points; for example, the value specified for ethanol at 1 ATM is 0.8722 moles, but the value obtained from the simulation for the column top is only 0.8056 moles
The number of plates or the reflux ratio might not be sufficient
Well, the Gata plates are sufficient, but the requirements set by the factory aren’t met; I don’t know how the factory manages to meet those requirements, damn it
I’m using DMC methanol; I’ve reached 500 trays, but the concentration still isn’t sufficient
There may be issues with the temperature and pressure parameters set. It’s also possible that there is an issue with the physical property method.
