Webbtages of a vertical shell-and-tube and a kettle reboiler. It is a thermosiphon reboiler with a low static head. The flow path of the medium is short and the cross section is large. The short flow path is an important benefit, because it makes bet-ter use of the static height, compared with a vertical shell-and-tube thermosiphon reboiler. WebbCirculating-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.
