The tower equipment is a device for material transfer between the gas phase and the liquid phase or between the liquid phase and the liquid phase.
The tower equipment are divided into two categories: plate tower equipment and packed tower equipment according to their structure.
A certain number of trays are arranged in the plate tower equipment, and the gas contacts the liquid layer on the trays in the form of bubbling or spraying for material transfer.
The packed tower equipment 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.
The storage tank is a sealed container used to store liquid or gas without mass and heat transfer. Commonly used are vault storage tanks, internal floating roof storage tanks, horizontal storage tanks and so on.
