A reboiler is a heat exchanger used in industrial processes, particularly in distillation columns. Its primary function is to provide heat to the bottom of the column, facilitating the vaporization of liquid. This process helps separate different components based on their boiling points, enhancing the efficiency of the separation process. Reboilers are commonly found in facilities that handle chemical processing, oil refining, and petrochemical production. They can be designed in various configurations, such as kettle or thermosyphon types, depending on the specific requirements of the system. Proper operation of a reboiler is crucial for maintaining optimal performance in these applications.
