This interactive training unit is designed to familiarize trainees with the basic principles of operation of distillation towers, reboilers, and condensers. After completing this unit, trainees should be able to describe the difference between a binary tower and a multidraw tower and explain why the physical dimensions of a tower can vary. They should also be able to explain why vacuum distillation and azeotropic distillation are used, and how various types of reboilers and condensers are used in distillation systems.

Towers and Processes

·         Describe the major difference between a binary tower and a multidraw tower.

·         Describe the basic operation of a side-draw tower.

·         Describe three factors that affect the physical dimensions of a distillation tower.

·         Given the name of a distillation tower, describe the tower’s main function.

·         Give three basic reasons why vacuum distillation is used.

·         Explain what an azeotropic mixture is and identify two methods of azeotropic distillation.

Reboilers and Condensers

·         Explain the difference between the following types of reboilers: forced versus natural circulation and external versus internal.

·         Describe two ways that condensers can be categorized in overhead systems.
