Distillation column trays
       Plate tower is a widely used gas-liquid mass transfer equipment. It consists of a usually cylindrical shell and a number of trays arranged horizontally at some intervals. When the plate tower is operating normally, the liquid passes through each layer of trays from top to bottom under the action of gravity and is discharged from the bottom of the tower; driven by the pressure difference, the gas passes through each layer of trays from bottom to top through the openings evenly distributed on the tray and is discharged from the top of the tower. There is some liquid stored on each tray. When the gas passes through the liquid layer on the plate, the two phases contact for mass transfer.

       The distillation tower is a tower-type vapor-liquid contact device for distillation, also called a distillation tower. There are two main types: plate tower and packed tower. According to the operation mode, it can be divided into continuous distillation tower and batch distillation tower. According to the operating pressure, it can be divided into three types: normal pressure, pressurized and reduced pressure. The basic principle of distillation is to partially vaporize and partially condense a liquid mixture multiple times,Taking advantage of the different volatilities of each component (relative volatility,α) characteristics to achieve unit operations for separation purposes. Distillation can be divided into simple distillation, flash distillation, rectification and special distillation according to its operation method.
