Azeotropic
Distillation Unit
An azeotropic distillation unit is a specialized separation system designed to break azeotropes. These are mixtures in which the vapor and liquid compositions are identical, making them impossible to separate by conventional distillation. Our azeotropic distillation apparatus overcomes this limitation by introducing a third component, known as an entrainer, which alters the vapor-liquid equilibrium and enables clean separation of the target components.
The azeotropic system operates by feeding the azeotropic mixture into a distillation column along with a carefully selected entrainer. The entrainer selectively interacts with one component, breaking the azeotrope and allowing the desired component to be purified through sequential vaporization and condensation stages. This technology is essential for applications such as ethanol dehydration (breaking the ethanol-water azeotrope), solvent recovery from complex mixtures, and purification of pharmaceutical intermediates.

How the Azeotropic Distillation Process Works
Feed mixture enters distillation column
The azeotropic mixture (e.g., ethanol-water) is fed into the distillation column at the optimal entry point.
Entrainer is introduced into the system
A carefully selected entrainer (such as benzene, cyclohexane, or toluene) is added to alter the vapor-liquid equilibrium.
Vapor-liquid equilibrium changes
The entrainer selectively interacts with one component, breaking the azeotrope and creating new separation pathways.
Separation by azeotropic distillation
Components separate based on their new boiling-point differences; the entrainer forms a low-boiling ternary azeotrope that is removed overhead.
Condensation and product recovery
The purified target component is collected from the column bottom, while the entrainer is recovered and recycled for continuous operation.

Azeotropic Distillation Unit FAQs
What is azeotropic distillation?
Azeotropic distillation is a specialized separation technique used to break azeotropes. These are mixtures where components have identical composition in both liquid and vapor phases, making them impossible to separate by conventional distillation. It uses an additional component (entrainer) to alter the vapor-liquid equilibrium.
How does an azeotropic distillation unit work?
What industries use azeotropic distillation equipment?
What is an entrainer in azeotropic distillation?
An entrainer is a third component added to an azeotropic mixture to alter its vapor-liquid equilibrium. Common entrainers include benzene, cyclohexane, toluene, and diethyl ether. The entrainer is selected based on its interaction with the target components and is typically recovered and recycled within the system.
