Such a reboiler differs from a thermosyphon reboiler in that it has a pump to force circulation, rather than relying on natural or thermosyphon circulation. This extra pump seems rather wasteful—and it is. The great advantage of forced circulation is that careful calculation of the pressure drop through… Read More »
