A Short Path Distillation Unit (SPDU) is also called as Molecular Distillation Unit. It is distinguished from a standard Agitated Thin Film Evaporator by an internally mounted condenser. The vapor generated on the heated surface travels a very short distance to reach the condenser surface, thus eliminating pressure drop.

Distillation is a separation technique that takes advantage of this phenomenon. In a simple distillation, a homogeneous liquid mixture is boiled. The rising vapor then enters the inner chamber of a water-cooled condenser. The vapor condenses to a liquid, called the distillate, which is then collected in a separate vessel.

EXPERIMENT 7 - Distillation – Separation of a Mixture. 2013-4-15 To understand the nature of simple distillation, fractional distillation and azeotropes we need to look at vapor/liquid diagrams for pairs of solvents. The graph below (Fig. 5) shows such a diagram for 2 solvents, A and B. A is the lower boiling material.

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.

Molecular distillation is a special liquid-liquid separation technology that operates under extremely high vacuum. It achieves the purpose of separation according to the physical characteristics of different molecular motions of different substances with different mean free paths. The liquid will be separated below the boiling point.

Molecular distillation occurs at low temperatures and reduces the problem of thermal decomposition. High vacuum also eliminates oxidation that might occur in the presence of air. The rate of evaporation is controlled by the rate at which the molecules escape from the free surface of the liquid and condense on the condenser. The effects of feed ...

Nov 03, 2014 Short path and molecular distillation were developed in the 1930s and 1940s mainly in the UK and in the USA. In short path distillation, the produced vapours do not have contact with the liquid any more. The number of theoretical stages is 1 at a small distillate rate and may rise up to 2.2 at a higher evaporation rate.
