MDC Distillation Plant

Short-path distillation, also known as molecular distillation, is a specialized technique used for separating compounds under high vacuum conditions. In this process, the fluids operate in the free molecular flow regime, meaning that the mean free path of the molecules is comparable to the dimensions of the equipment.

How It Works:

• The SPDU features an internally mounted condenser, which plays a critical role in its operation.
  
  

• The vapors generated from the heated surface travel a very short distance directly to the condenser surface.
  
  

• This design eliminates significant pressure drop, allowing operation at extremely high vacuum levels, typically down to 0.001 mbar.
  
  

• The short path ensures minimal thermal degradation of heat-sensitive materials by reducing residence time to only a few seconds.
  
  

Key Features:

• Minimum liquid hold-up: Reduces processing time and material loss.
  
  

• Ideal for heat-sensitive materials: Prevents decomposition or degradation of delicate compounds.
  
  

• Excellent turn-down capability: Allows processing of variable feed rates without loss of efficiency.
  
  

• High evaporation rate: Optimizes throughput while maintaining product integrity.
  
  

• Operates at high vacuum (0.001 mbar): Facilitates distillation of high-boiling or thermally unstable compounds.
  
  

• Heating temperatures up to 400°C: Suitable for processing a wide range of materials.
  
  

• Short residence time: Typically a few seconds, which is beneficial for sensitive products.
