I have a question regarding Aspen distillation column simulations: the temperature of the last tray (the reboiler) is much higher than the temperature of the final tray
Thread Content
I’m just starting to learn Aspen, so I’d like to ask everyone: in my simulations, the temperature at the bottom of the distillation column is much higher than the temperature of the last tray. Has anyone encountered this issue? Could some expert help take a look at the simulation? There’s also circulating hydrogen; when they’re connected together, it doesn’t work. How should this be adjusted?
Look at the components; the temperature is determined directly by them
The separation precision is too high, which results in a relatively single product profile; as a consequence, the temperature difference is large. I reduced the separation precision, and the temperature difference has since decreased
