Distillation Distillation is a commonly used method for purifying liquids and separating mixtures of liquids into their individual components. Familiar examples include the distillation of crude fermentation broths into alcoholic spirits such as gin and vodka, and the fractionation of crude oil into useful products such as gasoline and heating oil.

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 01, 2009 These results show that molecular distillation allows most compounds to be isolated from the raw bio-oil. Fig. 4 also shows that raising temperature promoted “Complete Isolation”, which was attributed to the fact that most of the compounds in this group had boiling points lower than 200 C, such as 2-propen-ol, 1-hydroxy-2-propanone, 2 ...
