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. WebIn a thermosyphon system, fluid flow is due to buoyancy forces produced by the difference in densities of the fluid in the collector and that of the cooler fluid in the store or application chamber.
