Issues regarding the stratifier in distillation columns
Thread Content
In the simulation of Aspen three-phase distillation, a decanter module can be added to the column to extract a certain liquid phase from the side stream. I would like to ask the experts: are there any examples of practical applications for this simulation? I’ve searched for a long time but haven’t seen any towers that use a middle stratifier. According to the teacher, even continuous liquid-liquid separators can significantly affect the residence time of the liquid on this plate; at the same time, it may happen that there isn’t enough liquid phase on the tray to enable stratification. I would also appreciate some guidance from experts. {:3_64:}
Indeed, the residence time can prevent stratification; in some towers even dry plates may form, so it’s necessary to observe more closely. But at most, it only ensures convergence
My simulation has produced results, with no errors. But I couldn’t find any examples of using intermediate layering devices… so I’m a bit confused
Post an example to take a look; I’m trying to learn… Generally, the intermediate stratifiers are placed outside the distillation tower, right? I’m not sure if they’re actually installed in the middle of the tower.
