WebCirculating-thermosiphon reboilers draw liquid from the tower bottoms, partially vaporize it, and deliver the two-phase fluid back to the tower bottoms above the liquid level. The difference in the static head pressure enables the circulation, as the partially vaporized fluid has a much lower density than the liquid entering the reboiler. WebJun 1, 1995 · Abstract. Thermosyphon reboilers provide a simple, low-maintenance design for distillation tower reboiler systems. With an understanding of all the factors involved, thermosyphon designs should be more reliable than most other reboiler systems due to an absence of moving parts (pumps) in the process circulation loop.
