Structured packing is made from exhaust corrugated metal sheets with slopes of 45 or 60 degrees, assembled into packages. These sheets can also be perforated. This type of packing is particularly suitable for using in low pressure and low hydraulic load systems, reducing pressure drop and energy consumption.

Structured packings can be made practically from any produced metal, including carbon steel, stainless steel (types 410, 304 and 316), steel duplex, aluminum, copper alloys, nickel alloys, titanium and zirconium.

They are produced with a large range of sizes, and corrugation height. The packing area can range from 50 m2 / m3 (lowest separation efficiency, highest productivity) to 750 m2 / m3 (highest efficiency, lowest productivity).

Structured packing is produced with two standard angles of corrugation inclination, and can be one of the following types:

Corrugation angle 45°, for most rectification units

Corrugation angle 60°, for units with a high liquid velocity, such as heat exchange layers


The structured packing supports perform the same functions as the random packing support (physical support for the packing, large area of passage that is not to limit the flow of liquid and gas, preventing the packing from moving downwards). These support grids provide the necessary free cross-section and remind the structure of the structured packing. The grids of the structured packing support can be made from various metallic and thermoplastic materials. Thanks to a special design, they can serve as a support for random packing.
