The tower is a process equipment with a cylindrical welded structure, which is composed of a cylinder, a head (or cover) and a support. It is a non-standard equipment specially designed and manufactured for a certain production process requirement. The tower is an upright equipment used for chemical unit operations such as distillation, purification, absorption, and rectification. It is widely used for mass transfer and heat transfer between gas-liquid and liquid-liquid phases.

The towers are divided into two categories: plate towers and packed towers according to their structure. A certain number of trays are arranged in the plate tower, and the gas contacts the liquid layer on the trays in the form of bubbling or spraying for material transfer. The packed tower is equipped with a certain height of packing, the liquid flows from top to bottom along the packing, and the gas is in countercurrent contact with the liquid film from bottom to top to carry out material transfer. It is often used in distillation, water absorption, extraction and other operations.
