Wire mesh structured packing has a high specific surface area, and due to the unique capillary effect of the wire mesh, the packing surface has good wettability, thus resulting in high separation efficiency. Compared with other packings, it has lower pressure drop and lower liquid holdup, making it particularly suitable for difficult-to-separate materials and heat-sensitive systems. The main materials used in manufacturing wire mesh packings include stainless steel, copper, aluminum, iron, and nickel .
Structured packing is packing material arranged and stacked in a uniform geometric shape within a tower. The entire tower section has a regular, symmetrical, and uniform geometry, defining gas-liquid flow channels, reducing channel flow and wall flow phenomena, and allowing for very low pressure drop. Under the same energy consumption and pressure drop conditions, it provides a larger specific surface area than random packing, achieving higher mass and heat transfer efficiencies for the same volume.
