Metal Perforated Corrugated Packing – Efficient Gas–Liquid Absorption

Metal Perforated Corrugated Packing is a high-efficiency Gas–Liquid Mass Transfer Packing composed of multiple layers of regularly arranged metal corrugated sheets. The metal sheet surfaces are typically provided with uniformly distributed perforations, while adjacent corrugated sheets are arranged in alternating orientations to form regular gas–liquid flow channels. This structure can increase the gas–liquid contact area and improve liquid wetting and distribution while maintaining a relatively low pressure drop.

Structured packing is available in two different inclination configurations: X-type and Y-type. “X”-type packing has an inclination angle of 30° to the horizontal axis and is used for high-throughput, low-pressure-drop applications. “Y”-type packing has an inclination angle of approximately 45° to the horizontal axis and is better suited to enhanced gas–liquid mixing and mass transfer; it is the most widely used packing configuration.

Features

Regular corrugated structure. It provides uniform gas–liquid contact. The corrugated sheets form continuous gas–liquid flow channels, helping improve gas and liquid distribution within the tower.
Low pressure drop. Suitable for operating conditions with high gas flow rates. Regular flow channels reduce random collisions and gas-flow resistance as gas passes through the packing bed.
High mechanical strength. Metal Structured Packing features metal construction with high mechanical strength, offering good structural stability, and can be used in high-temperature applications or operating conditions requiring high mechanical strength.
Modular installation. It is typically fabricated into packing elements or packing modules according to tower dimensions, facilitating layered installation, positioning, and replacement within the tower.
