The distillation tower is chemical equipment made of rare metal titanium and other materials and its alloy materials. It has the characteristics of high strength, high toughness, high temperature resistance, corrosion resistance, and light specific gravity. Therefore, it is used in chemical industry, petrochemical industry, metallurgy, light industry, textile, alkali production, pharmaceuticals, pesticides, electroplating, electronics and other fields.

Distillation tower principle and classification
       There are many types of tower equipment. The distillation tower is a tower-type gas-liquid contact device for distillation. There are two main types: plate tower and packed tower. The comparison between plate towers and packed towers is a complex issue involving many factors. When selecting, the material properties, operating conditions, performance of the tower equipment, and the manufacturing, installation, operation and maintenance of the tower equipment should be considered. The principle of distillation column distillation is to partially vaporize a liquid mixture and use the different volatilities of each component to achieve separation. The column kettle is liquid, and the gas is distilled from the top of the column.
       The working principle of the distillation column is not limited to the purification of alcohol. The main function of the distillation tower is to separate mixed liquids, using the principle of different liquids under different conditions, such as different temperatures and different volatilities (boiling points), to achieve purification effects. Distillation towers are mainly divided into plate towers and membrane towers. The plate tower is relatively common, and its structure can be divided into three parts: plate, reboiler, and condenser.
