Column Internals

Leading Column Internals Manufacturer

Column internals is the devices that interact and separate, widely used in industrial columns. These columns use a variety of components to perform their job, including trays, Mist Eliminator, Pad Demister, Liquid Distributor, Support Grid, Bed Limiter, Vane Type Demister, Packing support and so on.


Types of Column Internals

Pad Demister/Mist Eliminator
Pad Demister/Mist Eliminator

Wire mesh demister, also known as a wire mesh mist eliminator, is a kind of vapor liquid separating device. It is widely used in the chemical, petroleum, medical, light, metallurgy and environmental protection industries.

FAQs of Column Internals

  • What are the main column internals of the packed tower?

    They are mainly packing support device, packing compaction device, liquid distribution device, liquid collection and redistribution device, etc. Reasonable selection and design of tower internals is very important to ensure the normal operation of the packed tower and excellent mass transfer performance.


  • What are the common column internals of packing support tower?

    Commonly used packing support tower column internals include grid plate type, perforated tube type, hump type and so on. The selection of the supporting device is mainly based on the tower diameter, the type and model of packing, the material of the tower body and packing, and the gas-liquid flow rate.


  • What are the types of liquid distribution devices for column internals?

    There are various types of liquid distribution devices, such as nozzle type, disk type, tube type, trough type and trough disk type. For packed towers with large diameters and low packing layers, a liquid distribution device with good performance is particularly required.
