Regarding the theoretical plate number of the tower
Thread Content
The existing distillation columns all use falling film reboilers. Based on the configuration shown in the diagram, which column’s bottom product has a higher content of heavy components, and is there any difference in the number of theoretical plates of these columns?
Of course, the reconstituted fraction obtained through the first process has a higher content; the reboiler functions as a kind of tray. In the second process, the liquid coming out of the reboiler (tray) is mixed with the liquid from the previous tray in the reactor bottom before it is taken out. The first process and the second process differ by half a tray.
