In this work, important results from simulations are presented, showing the potentiality of the molecular distillation process for recovering vitamin E from vegetal oils. Two types of molecular distillators are considered: falling film and centrifugal. The results emphasize the degree of recovery and factors that influence substantially the performance of the molecular distillators, …

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 became an important industry during the past fifteen years, and has enabled many thermally sensitive materials to be prepared on a commercial scale, but the development of stills appears now to have reached a resting-point. After a short introduction, the author discusses in turn the various forms of molecular still existing at the present time, …

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 is a technology made exclusively for liquid-liquid separation. While traditional distillation does so with the boiling point difference separation principle, this method separates substances at the molecular level. This allows for a safer and purer technique of distillation. This method also produces a shorter residence ...

The meaning of MOLECULAR DISTILLATION is distillation that is carried out under a high vacuum in an apparatus so designed as to permit molecules escaping from the warm liquid to reach the cooled surface of the condenser before colliding with other molecules and consequently returning to the liquid and that is used in the purification of substances of low volatility (as in …

Vacuum distillation in the petroleum industry has not up to the present received the attention it deserves. Plants for the distillation of lubricating oils are often operated under vacuum, but this is seldom sufficiently high to give the best results, in many cases, indeed, being so low as to have little marked effect on the distillation. The advantages of distilling under vacuum are: -The ...
