Rotating Belt Distillation Column

A rotating belt distillation column is a type of distillation column used for separating liquids with very similar boiling points.

The main features of this equipment are:
Efficient separation: It is designed to separate compounds with very similar boiling points, which is difficult to achieve with simpler distillation columns such as the Vigreux column.

Presence of a rotating belt: Inside the column tube is a rotating device that rotates at high speed. This device creates a thin liquid film and increases the exchange surface area between the liquid and vapor phases, thus improving separation efficiency.

Operating principle: The rotating belt allows for multiple evaporation and condensation cycles along the column, simulating a large number of theoretical plates and allowing for better vapor rectification.

Applications: It is particularly useful in laboratories for the purification of chemicals or the separation of complex mixtures, where high purity is required.
