3 Characteristics of molecular distillation operation

3 Characteristics of molecular distillation operation

Dec 27, 2021 2. Low distillation pressure requires the operation of molecular distillation under high vacuum. The molecular Mean free path is inversely proportional to the system pressure. Only by increasing the vacuum can a large enough Mean free path be achieved. The results show that the vacuum degree of molecular distillation is 0.1-100Pa. 3.

distillation, the new phases differ from the original by their heat content. During most of the century, distillation was by far the most widely used method for separating liquid mixtures of chemical components (Seader and Henley, 1998). This is a very energy intensive technique, especially when the relative volatility of

Principle and Procedure of Molecular Distillation

May 13, 2021 Working of Molecular Distillation: The vessel walls are heated suitably by a heating jacket. The feed flows down the walls and is spread to a film by the polytetrafluoroethylene (PTFE) wipers which move about 3 m/s giving a film velocity of about 5 ms. Due to heat liquid film evaporates and vapors hit the condenser.
