Puhastuskolonn

Puhastuskolonn, also known as a purification column or purification tower, is a type of chemical engineering equipment used to separate components from a mixture by selective absorption or adsorption. It is commonly used in the chemical, petrochemical, and pharmaceutical industries for processes such as distillation, absorption, and stripping.

A puhastuskolonn typically consists of a vertical cylindrical column filled with a packing material, such as Raschig rings, Pall rings, or structured packings. The packing material increases the surface area available for mass transfer between the liquid and gas phases. The column is equipped with trays or packing material to facilitate the separation process.

The operation of a puhastuskolonn involves the introduction of a feed mixture into the column, which is then heated or cooled to promote the desired separation. The mixture is distributed evenly across the column, and the components are separated based on their different boiling points, solubilities, or adsorption characteristics. The separated components are then collected from the top and bottom of the column.

Puhastuskolonn are designed to handle a wide range of feed mixtures and operating conditions, making them versatile and essential equipment in various industrial processes. They are known for their efficiency in separating components with minimal energy consumption and environmental impact.
