WebJan 10, 2012 · Let us discuss something about Thermosyphon Reboiler, You might be aware of its benifits that it has good heat transfer efficiencies. Its rule of thumb that 1:4 is the vapor/liquid ratio in the outlet of reboiler. When as a vertical length of tubes, liquid starts vaporizing, and density of the mixture is reducing, which is a driving force to ... 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. WebThermosyphon reboilers are horizontal with the process fluid on the shell side, or vertical with the process on the tube (most frequently) or the shell side.

WebOct 14, 2014 · Thermosiphon reboiler is usually used in applications where the vaporization is not very high. i.e only about a max of 20-30% of the inlet liquid to the reboiler is vaporized. The reason given is too much vaporization can cause low heat transfter coefficient and make areas high because of bubbling, vapor blanketing and such.
