How a reboiler works

WebThe reboiler is a vertical thermosyphon reboiler. A schematic of the reboiler and the bottom part of the column is shown in Fig. 3. According to Kister (1992), the shown arrangement, where the circulated liquid directly enters the bottom product sump, makes the reboiler work as an ideal stage. Reboilers are heat exchangers typically used to provide heat to the bottom of industrial distillation columns. They boil the liquid from the bottom of a distillation column to generate vapors which are returned to the column to drive the distillation separation.

WebHow does a reboiler work? Reboilers are heat exchangers typically used to provide heat to the bottom of industrial distillation columns. They boil the liquid from the bottom of a distillation column to generate vapors which are returned to the column to drive the distillation separation. Web4 de jan. de 2005 · It will work although you might want to add another tray or two to the column. The simulation assumes a theoretical tray for the reboiler that is not accounted for. Also, the actual reboiler duty may be slightly higher (but not much) than calculated because of the mixing of the reboiler return liquid with the bottom tray liquid.
