The GUNT Discontinuous Rectification Unit is designed to demonstrate batch distillation, a thermal separation process used to separate fully miscible liquid mixtures such as ethanol and water. This hands-on system provides an in-depth look at rectification in counterflow with practical experimentation using real process components.
Product Features
- Educational unit for studying batch rectification and thermal separation of liquid mixtures
- Operates with ethanol/water mixtures for demonstration purposes
- Liquid mixture is heated in the evaporator tank to produce mixed vapour
- Vapour enriched in ethanol rises through the column and is condensed at the top
- Condensate is split between product tank and reflux return to the column
- Descending liquid interacts with rising vapour to enrich vapour in ethanol and liquid in water
- Two interchangeable columns: sieve tray column and packed column filled with Raschig rings
- Reflux ratio adjustable using precision valves
- Evaporator temperature precisely controlled using a PID controller
- All relevant process parameters digitally monitored and displayed on the switch cabinet
- Clear process schematic on cabinet for easy identification of process variables
Benefits
- Offers practical understanding of countercurrent mass and heat transfer in batch distillation
- Interchangeable column design supports comparative studies between tray and packed columns
- Enables accurate control and visualization of reflux and temperature profiles
- Ideal for educational settings in chemical engineering, process design, and distillation theory
