I would like a confirmation for the procedure to model a thermosyphon reboiler attached to a distillation column.
I remember the procedure I used was to define a side stripper or a separator with one theoretical tray (tray N+1) and an energy stream (representing the bottom duty), net liquid from the column bottom tray (tray N) feeds tray N+1, liquid from tray N+1 feeds tray N, vapour stream from tray N+1 feeds tray N-1, a vapour feed stream with zero flowrate feeds tray N+1. The addition of this unit operation generates a freedom degree to the simulation and a new specification is required.
I will appreciate your help in the confirmation of this procedure and what should be the specification. I got this procedure in my engineering notes, but I have no access to it.
