About Kettle Type Heat Exchanger

In this kettle reboiler type / kettle type heatexchangers, steam flows through the tube bundle and exits as condensate. The liquid from the bottom of the tower, commonly called the bottoms, flows through the shell side. There is a retaining wall or overflow weir separating the tube bundle from the reboiler section where the residual reboiled liquid (called the bottoms product) is withdrawn, so that tube bundle is kept covered with liquid.Kettle reboilers are reliable in that they can handle high vaporization of up to 80 percent and are easy to maintain.

Kettle reboilers are very simple and reliable. They may require pumping of the column bottoms liquid into the kettle, there may be sufficient liquid head to deliver the liquid into the reboiler.

In a typical classical distillation column, all the vapor driving the separation comes from the reboiler. The reboiler receives a liquid stream from the column bottom and may partially or completely vaporize that stream. Steam usually provides heat required for the vaporization. Reboilers are heat exchangers typically used to provide heat to the bottom of industrial distillation columns. They boil the liquid from the bottom of a distillation column to generate vapors which are returned to the column to drive the distillation separation. Proper reboiler operation is effective distillation.
