Product Specification Sheet
Fractional Distillation Unit – 20 L to 500 L
Model Number: MTDU-01
The Fractional Distillation Unit – 20 L to 500 L from Micro Technologies is designed for the separation, purification and recovery of liquid mixtures based on differences in boiling points. The system incorporates a vessel, heating arrangement, fractionation column, reflux divider, condenser, product cooler and receivers to provide controlled fractional distillation for laboratory scale-up, pilot plant and process applications.
Product Specification
The Fractional Distillation Unit is a process system used to separate liquid mixtures containing components with different boiling points. Compared with simple distillation, the incorporation of a fractionation column and reflux arrangement enables repeated vaporization and condensation, improving separation efficiency.
The unit shown is available in capacities ranging from approximately 20 litres to 500 litres, making it suitable for pilot-scale development as well as larger process requirements.
The feed material is charged into the distillation vessel, where it is heated using a suitable heating bath or heating arrangement. As the liquid temperature increases, volatile components vaporize and enter the fractionation column.
Inside the fractionation column, repeated vapour-liquid contact helps separate components according to their relative volatility. Vapour leaving the upper section passes through a condenser, where it is converted back into liquid.
A reflux divider controls the proportion of condensed liquid returned to the fractionation column and the proportion directed toward product collection. This allows improved control over separation and product purity.
The collected distillate passes through a product cooler and then into the receiving arrangement. Vacuum operation can also be incorporated where reduced-pressure distillation is required for suitable heat-sensitive or high-boiling materials.

Working Principle
1. Feed Charging
The liquid mixture to be separated is introduced into the distillation vessel.
2. Controlled Heating
The vessel is heated using the heating bath or selected heating system. As the temperature rises, the more volatile components preferentially enter the vapour phase.
3. Fractionation
The generated vapour travels upward through the fractionation column. Repeated condensation and re-vaporization within the column improve separation between components of different volatility.
4. Vapour Condensation
Vapour reaching the top of the column enters the condenser, where cooling converts it back into liquid.
5. Reflux Control
The reflux divider directs part of the condensate back into the fractionation column. The remaining portion is withdrawn as distillate.
Adjusting the reflux ratio can influence separation performance and product purity.
6. Product Cooling
The withdrawn distillate passes through the product cooler to reduce its temperature before collection.
7. Product Collection
The condensed and cooled product is collected in the receiving vessel. Suitable receiver arrangements allow convenient collection and discharge.

Fractionation Column
Improved Separation Efficiency
The fractionation column provides a larger contact area between ascending vapours and descending condensate.
This repeated vapour-liquid interaction allows the system to achieve better separation than a basic simple-distillation setup, particularly when the components have relatively close boiling points.
Reflux System
Reflux Divider
The reflux divider is an important component of the system. It controls how much condensed liquid is:
- Returned to the fractionation column
- Withdrawn as product
Proper reflux control helps optimize separation efficiency, product purity and processing time.
Vacuum Distillation Provision
Reduced-Pressure Operation
The system can incorporate a vacuum connection for processes requiring reduced-pressure distillation.
Operating under vacuum lowers the boiling temperature of liquids, which can be useful for suitable:
- Heat-sensitive materials
- High-boiling solvents
- Temperature-sensitive products
- Specialty chemicals
The actual allowable vacuum level depends on the construction and rated configuration of the supplied system.
