—— Operation

Feed liquid is admitted into still under high vacuum, immediately spread into a very thin film and forced quickly down the evaporation surface. Heated walls and high vacuum drive the more volatile components (distillate) to the external condenser as the less volatile components (residue) continue down the cylinder. The resulting fractions, thus separated, exit through individual discharge outlets. Depending on application, the desired product is either the distillate or the residue fraction. Small amounts of condensable low MW compounds collect in cold trap upstream of vacuum system. For high solvent loads, an optional external condenser may be installed immediately downstream of the still.

Where,
Q is the evaporated quantity kg/h,
P = pressure (mbar),
F = evaporator surface (m22 ),
k = 1577,
M = molecular weight g/mole,
T is absolute temperature (K).

Theoretically the molecular distillation could also be used for separating mixtures which have close boiling point or forming azeotrope.

Further development took place in this field after the Second World War and very soon it was found that the gentle distillation conditions still exists at higher temperature where no molecular distillation conditions were provided. So that also gave a new meaning to the whole idea that distillate rate is not limited by free path of vapour molecules.
