In thermosyphon reboilers, natural circulation is obtained by using the density difference between the reboiler column bottoms liquid and the reboiler outlet vapour-liquid mixture to provide sufficient liquid head to deliver the tower bottoms into the reboiler. What is a kettle type reboiler?

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.
