Reboilers Heat Exchanger normally used to present 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 vital to effective distillation. In a typical classical distillation column, the entire vapor driving the partition comes from the reboiler. The reboiler receives a liquid tributary from the column bottom and may partially or completely vaporizes that stream. Steam usually provides the heat required for the vaporization.
