Fractional distillation in a laboratory makes use of common laboratory glassware and apparatuses, typically including a Bunsen burner, a round-bottomed flask and a condenser, as well as the single-purpose fractionating column. Fractional distillation. As an example, consider the distillation of a mixture of water and ethanol. Ethanol boils at ...

A fractionating column or fractional column is equipment used in the distillation of liquid mixtures to separate the mixture into its component parts, or fractions, based on their differences in volatility. Fractionating columns are used in small-scale laboratory distillations as well as large-scale industrial distillations.
Distillation column in a cryogenic air separation plant. The cryogenic separation process [4] [5] [6] requires a very tight integration of heat exchangers and separation columns to obtain a good efficiency and all the energy for refrigeration is provided by the compression of the air at the inlet of the unit.
Here the distillation head and fractionating column are combined in one piece. Differential centrifugation . Fractionation is a separation process in which a certain quantity of a mixture (of gasses, solids, liquids, enzymes , or isotopes , or a suspension ) is divided during a phase transition , into a number of smaller quantities ( fractions ...
For the binary distillation depicted in Figure 1, the required number of theoretical plates is 6. Constructing a McCabe–Thiele diagram is not always straightforward. In continuous distillation with a varying reflux ratio, the mole fraction of the lighter component in the top part of the distillation column will decrease as the reflux ratio ...
In 1651, John French published The Art of Distillation, [30] the first major English compendium on the practice, but it has been claimed [31] that much of it derives from Brunschwig's work. This includes diagrams with people in them showing the industrial rather than bench scale of the operation.
Key fractional distillation concepts: theoretical stages, x-y diagrams, multicomponent distillation, column composition and temperature profiles Process design and optimization : minimum reflux and minimum stages, optimum reflux, short-cut methods, feed entry location
