Reactor plate resonance at the lower operating limit of a distillation column
Thread Content
The distillation column is operated at its lower limit; when the gas flow rate is low, plate resonance occurs, causing the liquid layer on the plates to vibrate up and down in a regular pattern. It is generally believed that the pressure buildup and release of gas in the valve holes cause vertical vibrations of the liquid layer on the tray. Why, then, is the height of this liquid layer consistent and evenly distributed across the tray? Can this be analyzed from a mechanistic perspective, using the concept of Gibbs free energy? ? Please advise~
I think it is determined by the structural characteristics of the floating valve tower itself; the pressure buildup and release on the floating valves occur at a relatively constant frequency, so resonance is a normal phenomenon. This phenomenon is favorable for mass transfer~
2# yantaiyukai: In the resonant state, the tray plates are completely leaky, resulting in severe backmixing; this is likely not conducive to mass transfer and has a significant impact on the equipment~~
