Distillation

Distillation columns: separation of liquid products using their boiling points

Separating the components of a homogeneous mixture of liquids using their boiling points is a recurrent operation in the chemical, petrochemical, food and pharmaceutical industries. At Foeth we have a wide range of used distillation columns available from leading international brands such as Sulzer, Buechi, Pharmatec Dresden, Stilmas, Duker GmbH and many others.

Industrial distillation column: definition and working principle

A distillation column is an essential equipment in the fractionation of liquid mixtures. It is used in the separation of the components or fractions present in the product, according to the boiling points of the different elements.

In industrial fractionation columns, the product is heated until the components begin to vaporise and move up the vertical column, so that the lighter components, with lower boiling points, are separated in the upper section of the column, while the heavier components remain at the bottom.

As the vapour rises, it condenses and descends on a series of plates or packings contained inside the column. It is on these elements that the liquid reaches equilibrium with the vapour, so that the rising vapour phase is enriched in the more volatile components, while the heavier ones remain on the plates or in the lower zones. This factor is used to achieve the separation of the different components.

Different types of industrial distillation columns available at Foeth

Our distillation columns are ideal for industrial operations, but there is also equipment designed for laboratory-level separation. In order to achieve a better separation of the products, they can work at reflux, re-entering part of the distilled material at the top of the column. As the reflux increases or the number of trays increases, a higher degree of separation is achieved.

In our warehouse you will find packed distillation columns, where the separation takes place by continuous contact on the packing elements, obtaining products at the top and bottom of the column. The packings are selected according to the type of separation and the characteristics of the products to be separated.

We also have liquid-liquid extraction columns, used in the purification of products. If you need additional information about our industrial distillation columns, please call or write to us via the Foeth contact form.
