The reboiler in the distillation tower is located at the bottom of the tower, and its main function is to partially or completely vaporize the liquid at the bottom of the tower, generating rising steam to maintain the gas-liquid mass transfer process inside the tower. According to whether all liquids are vaporized, they can be divided into partial reboiler and total reboiler.

 This distillation column with reboiler device is widely used in fields such as petroleum refining, solvent recovery, and fine chemicals.

Basic process: After entering the distillation tower, the raw materials undergo multiple gas-liquid contacts on the tray or packing, with light components enriched upwards and heavy components enriched downwards; The liquid at the bottom of the tower is heated by the reboiler and returned to the tower to form rising steam.
Reboiler type:
Thermosiphon suction
Forced loop type
Built in or Stirred Tank
(Additional explanation) The design of a reboiler should consider heat transfer efficiency, pressure drop control, and corrosion risk, especially when dealing with aqueous or acidic systems, where material selection is particularly important
A distillation tower with a reboiler is one of the most common and critical equipment in chemical separation processes. It achieves gas-liquid equilibrium by providing thermal energy at the bottom of the tower, thereby completing component separation; The heat load of the reboiler directly affects the temperature distribution, reflux ratio, and separation efficiency inside the tower
