This new continuous distillation method produced whisky much more efficiently than the traditional pot stills, [14] without the need for cleaning after each batch was made. [ 15 ] As the reciprocating steam engines of the time were unable to feed the still with the necessary high temperature/pressure steam, it took some time for the Coffey ...
Image 1: Typical industrial distillation towers Image 2: A crude oil vacuum distillation column as used in oil refineries. Continuous distillation, a form of distillation, is an ongoing separation in which a mixture is continuously (without interruption) fed into the process and separated fractions are removed continuously as output streams.
The simplest standard distillation apparatus is commonly known as a pot still, consisting of a single heated chamber and a vessel to collect purified alcohol. A pot still incorporates only one condensation, whereas other types of distillation equipment have multiple stages which result in higher purification of the more volatile component ...
Distillation, also classical distillation, is the process of separating the component substances of a liquid mixture of two or more chemically discrete substances; the separation process is realized by way of the selective boiling of the mixture and the condensation of the vapors in a still. Dry distillation (thermolysis and pyrolysis) is the ...
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 ...
This was how Coffey became familiar with a design differing from the traditional copper pot alembic still commonly used in Ireland, the continuous, or column, still. First patented by a Cork County distillery in 1822, the column still remained a relatively inefficient piece of equipment, although it pointed the way towards a cheaper and more ...
