Packed columns . Packed towers with dumped or regular packings are widely used in industry for accomplishing chemical engineering processes. Packed columns are able to work economically even under extreme process conditions (e. g. vacuum, high temperature, aggressive flow mediums), because of the available variety of packing types and the straight‐forward manufacture of the individual packing elements from almost any material. The present contribution shows the different kinds of packings arranged according to their geometry and physical properties. A packed tower for gas/liquid countercurrent operation is shown as a basic construction with the necessary internals. Since packed columns are mostly used in gas/liquid countercurrent operation, the fundamentals of fluid dynamics and mass transfer are presented for this operating condition.
