Simple liqueur distillation in East Timor As alchemy evolved into the science of chemistryvessels called retorts became used for distillations. Both alembics and retorts are forms of glassware with long necks pointing to the side at a downward angle which acted as air-cooled condensers to condense the distillate and let it drip downward for collection.

Later, copper alembics were invented. Riveted joints were often kept tight by using various mixtures, for instance a dough made of rye flour. These were called pot stills. Today, the retorts and pot stills have been largely supplanted by more efficient distillation methods in most industrial processes.


However, the pot still is still widely used for the elaboration of some fine alcohols such as cognacScotch whiskyIrish whiskey, tequila and some vodkas. Pot stills made of various materials wood, clay, stainless steel are also used by bootleggers in various countries.

Small pot stills are also sold for the domestic production [20] of flower water or essential oils. Early forms of distillation were batch processes using one vaporization and one condensation. Purity was improved by further distillation of the condensate.

Greater volumes were processed by simply repeating the distillation. Chemists were reported to carry out as many as to distillations in order to obtain a pure compound. InRobert Stein improved that design to make his patent still. InAeneas Coffey got a patent for improving that design.

The French engineer Armand Savalle developed his steam regulator around Patent for a tray column for ammonia distillation [24] and the same and subsequent years saw developments of this theme for oil and spirits.

With the emergence of chemical engineering as a discipline at the end of the 19th century, scientific rather than empirical methods could be applied. The developing petroleum industry in the early 20th century provided the impetus for the development of accurate design methods such as the McCabe—Thiele method by Ernest Thiele and the Fenske equation.

The availability of powerful computers has also allowed direct computer simulation of distillation columns. Applications of distillation[ edit ] The application of distillation can roughly be divided in four groups: The latter two are distinctively different from the former two in that in the processing of beverages and herbs, the distillation is not used as a true purification method but more to transfer all volatiles from the source materials to the distillate.

The main difference between laboratory scale distillation and industrial distillation is that laboratory scale distillation is often performed batch-wise, whereas industrial distillation often occurs continuously.

In batch distillationthe composition of the source material, the vapors of the distilling compounds and the distillate change during the distillation. In batch distillation, a still is charged supplied with a batch of feed mixture, which is then separated into its component fractions which are collected sequentially from most volatile to less volatile, with the bottoms remaining least or non-volatile fraction removed at the end.

The still can then be recharged and the process repeated. In continuous distillationthe source materials, vapors, and distillate are kept at a constant composition by carefully replenishing the source material and removing fractions from both vapor and liquid in the system.

This results in a more detailed control of the separation process. Idealized distillation model[ edit ] The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the pressure around the liquid, enabling bubbles to form without being crushed.

A special case is the normal boiling pointwhere the vapor pressure of the liquid equals the ambient atmospheric pressure.

It is a common misconception that in a liquid mixture at a given pressure, each component boils at the boiling point corresponding to the given pressure and the vapors of each component will collect separately and purely.Fractional Distillation head All 24/40 ground joints Vigreux column Precision 24/40 Vigreux Distilling Column, mm.

Distilled spirits are all alcoholic beverages in which the concentration of ethyl alcohol has been increased above that of the original fermented mixture by a method called distillation.

The principle of alcoholic distillation is based upon the different boiling points of alcohol ( °C, or .
