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. The heat supplied to the column by the reboiler at the bottom of the column is removed by the condenser at the top of the column.

Proper reboiler operation is vital to effective distillation. 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 the heat required for the vaporization.

A Shell & Tube Heat Exchanger is a pressure vessel designed to efficiently transfer heat between two process fluids. It consists of a cylindrical shell housing a tube bundle, where one fluid flows through the tubes (tube side) and the other flows across the tubes within the shell (shell side). Heat is transferred through the tube walls by conduction and enhanced by convection due to induced turbulence.

• Fixed Tube Sheet: Economical, suited for clean fluids.

• U-Tube Design: Allows thermal expansion, ideal for high-temperature services.

• Floating Head Design: Facilitates easy cleaning of both shell and tube side, used for fouling services.
