Fractionating Packing Column tower for chemical plant

Product Description

Packing distillation tower is a common chemical equipment used to separate different components in a mixture. Its working principle is to utilize the differences in physical and chemical properties of different components in the packing layer, and gradually separate the components in the mixture through steam condensation and liquid reflux

The working principle of a packed distillation tower is to utilize the volatile differences of different substances in the packing layer, and continuously separate and collect the substances in the packing layer through process steps such as heating, evaporation, cooling, and condensation.

The structure of a packed distillation tower is relatively simple, mainly composed of the tower body, packing layer, feed inlet, discharge outlet, steam inlet, condenser, and liquid reflux pipe. Among them, the packing layer is an important part inside the tower, which can increase the contact area between the mixture and steam, thereby improving the separation efficiency. There are many types of packing layers, commonly including annular packing, spherical packing, skeleton packing, etc. The shape and material of these fillers have different effects on separation efficiency and mass transfer rate.

Application of Fractionating Packing Column tower is a device that promotes gas-liquid contact mass transfer by filling specific packing materials. It is commonly used in various chemical processes for gas-liquid separation, mixture mass transfer, vaporization, absorption, regeneration, purification, and other processes. The packed tower is particularly suitable for vacuum distillation, distillation under normal and medium pressure, as well as two-phase contact processes with atmospheric volume (such as gas absorption, cooling, etc.). In addition, the application of packed columns in air separation units is becoming increasingly widespread. For example, using regular packing in crude argon columns can improve the purity of argon gas
