Multistage Distillation System Introduction

Vacuum Distillation Equipment, it is a process of separation, purification and concentration of natural products, complex and thermally sensitive molecules for example vitamins and polyunsaturated fatty acids. This process is characterized by short term exposure of the distillate liquid to high temperatures, by high vacuum pressure (around 1024 mmHg) in the distillation column and a small distance between the molecular distillation and the condenser around 2 cm, where fluids are in the free molecular flow regime, i.e. the mean free path of molecules is comparable to the size of the equipment. This process has the advantages of avoiding the problem of toxicity that occurs in techniques that use solvents as the separating agent, and also of minimizing losses due to thermal decomposition.

——Particular features

Continuous distillation process.
Very low operating pressures up to 0.1Pa (100Pa=1mba). (The considerably lower pressure in the short path evaporator is obtained by the short distance for the vapours on their way from the evaporator surface to the condenser. )
The very low operating pressures ensure very low distillation temperatures and therefore a very gentle distillation is possible.
Short residence time. (Thanks to the short residence time, the low evaporation temperature and the immediate cooling of the concentrate, thermal stress and decomposition of the product can be minimized.)
High evaporation rates.

——Fields of application

For the thermal separation of high molecular and high-boiling products.
For heat sensitive materials.
