A column still is an example of a fractional distillation, in that it yields a narrow fraction of the distillable components. This technique is frequently employed in chemical synthesis; in this case, the component of the still responsible for the separation is a fractionating column .
Pot still distillation gives an incomplete separation, but this can be desirable for the flavor of some distilled beverages. If a purer distillate is desired, a reflux still is the most common solution. Reflux stills incorporate a fractionating column, commonly created by filling copper vessels with glass beads to maximize available surface ...
The result was more efficient, producing a lighter spirit at higher alcohol content. Coffey patented his design in 1830, and it became the basis for every column still used ever since. His column still became widely popular in Scotland and the rest of the world outside Ireland, where it is known as the "Coffey still" or "Patent Still".
A spiral still is a type of column still with a simple slow air-cooled distillation apparatus, commonly used for bootlegging. [9] Column and cooler consist of a 5-foot-long (1.5 m) copper tube wound in spiral form. The tube first goes up to act as a simple column, and then down to cool the product.
The simplest and most frequently used batch distillation configuration is the batch rectifier, including the alembic and pot still. The batch rectifier consists of a pot (or reboiler), rectifying column, a condenser, some means of splitting off a portion of the condensed vapour (distillate) as reflux, and one or more receivers.

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.
An OpenAI spokesperson told me by email that it's aware that Chinese firms "are actively working to use methods, including what’s known as distillation, to try to replicate advanced U.S. AI models.
The distillery features both column stills and pot stills for distillation. Unlike most other Irish whiskeys, which are usually distilled three times, Cooley's products are generally distilled twice, as the third distillation is thought to remove some of the flavour components.
