The tower is divided into plate tower and packed tower according to structure
The tower is a process equipment with cylindrical welded structure, which is composed of cylinder, head (or cap) and support. It is a non-standard equipment specially designed and manufactured for certain production process requirements. The tower is a vertical equipment used for distillation, purification, absorption, distillation and other chemical unit operations. It is widely used for mass and heat transfer between gas-liquid and liquid-liquid phases. According to the structure of tower internals, the tower can be divided into plate tower and packed tower. If the container only contains materials without chemical reaction and other physical and chemical processes, there are no facilities or only simple auxiliary structures, it is also called a tank. Vessels are divided into vertical (vertical axis) and horizontal (horizontal axis) by type. Most of the columns are pressure vessels.

Equipment for material transfer between gas and liquid phases or between liquid and liquid phases. According to the structure, it is divided into two categories: plate tower and packed tower. A certain number of trays are set in the tray tower, and the gas contacts with the liquid layer on the tray in the form of bubbling or jetting for material transfer. A certain height of packing is installed in the packing tower. The liquid flows from top to bottom along the packing, and the gas contacts with the liquid film countercurrent from bottom to top to transfer substances. It is often used in distillation, water absorption, extraction and other operations.
