Metal structured packing is a type of high-efficiency tower packing with a regular geometric structure. It is made from thin metal sheets through precision processing. Thanks to the high strength, high temperature resistance and other properties of metal materials, it occupies an important position in the field of industrial separation. Through its orderly structural design, it provides an ideal contact environment for gas-liquid mass transfer. Compared with random packing, it can more efficiently realize gas-liquid separation and mass transfer processes.

1. Metal Corrugated Structured Packing: This is the most widely used type of metal structured packing. Its core structure consists of a series of parallel arranged corrugated thin metal sheets. The corrugation directions of adjacent sheets are perpendicular to each other, forming a network of intersecting channels. According to different corrugation angles, it can be divided into common types such as 30° and 45°. Different angles are suitable for different gas-liquid load conditions. The 30° angle packing is suitable for low pressure drop and large throughput scenarios, while the 45° angle focuses more on improving mass transfer efficiency.

1. Metal Mesh Structured Packing: Uniform mesh structures are stamped on the surface of thin metal sheets, which combines the channel characteristics of corrugated packing with the capillary action of the mesh. This structure can enhance the uniformity of liquid distribution on the packing surface, improve gas-liquid contact efficiency, and is especially suitable for processes with high requirements for separation accuracy such as precision distillation.

1. Metal Plate-Mesh Structured Packing: It is made of metal plate-mesh materials into a corrugated structure, combining the strength of metal plates with the advantage of high specific surface area of mesh materials. The microporous structure on its surface can strengthen the renewal of liquid film, improve mass transfer rate, and is often used in the separation process of difficult-to-separate systems.

1. High Strength and High Temperature & Pressure Resistance: Metal materials (such as stainless steel, carbon steel, aluminum alloy, etc.) endow the packing with extremely high mechanical strength, which can withstand high pressure and weight loads during the operation of tower equipment. At the same time, it can withstand high-temperature environments and maintain structural stability under working conditions of hundreds of degrees Celsius, making it suitable for high-temperature and high-pressure reaction and separation processes.

1. Excellent Mass Transfer Performance: The regular channel structure makes the gas-liquid flow distribution uniform, reduces phenomena such as channeling and wall flow, and greatly improves gas-liquid contact efficiency. Its large specific surface area provides sufficient space for mass transfer, and the mass transfer efficiency is much higher than that of traditional random packing.

1. Low Pressure Drop and High Flux: The reasonable channel design reduces the resistance of gas passing through the packing layer, resulting in small pressure loss. At the same time, it allows high gas-liquid flux, which can meet the processing requirements of large-scale industrial production and improve the production capacity of equipment.

1. Optional Corrosion Resistance: Appropriate metal materials can be selected according to the corrosiveness of the process medium. Stainless steel (304, 316, 316L, etc.) has excellent acid and alkali corrosion resistance and is suitable for working conditions containing corrosive media; carbon steel materials are suitable for non-corrosive or weakly corrosive environments, taking into account economy and practicability.

1. Strong Structural Stability: Metal materials are not easy to deform, and can maintain a regular structural shape during long-term operation, ensuring the stability and consistency of packing performance and prolonging the service life of equipment.

1. Petrochemical Industry: Widely used in distillation towers and absorption towers in petroleum refining, such as the separation and purification of fractions like gasoline and diesel, as well as processes such as natural gas purification and petroleum gas separation. It can effectively improve product purity and yield.

1. Fine Chemicals and Pharmaceuticals: In processes such as solvent recovery in fine chemicals and purification and separation of pharmaceutical intermediates, the high-precision separation performance of metal structured packing can meet the production requirements of high-purity products and ensure product quality.

1. Environmental Protection and Energy Field: In industrial waste gas desulfurization and denitrification towers and biogas purification equipment, metal structured packing can withstand high-temperature flue gas and corrosive media, efficiently promote gas-liquid reactions, and improve pollutant removal efficiency; it also plays a key role in coal chemical separation processes in the energy field.

1. Metallurgical and Coking Industries: Used in gas purification towers in the metallurgical industry and gas refining towers in the coking industry, etc., it can remove impurities such as hydrogen sulfide and hydrogen cyanide from coal gas, purify process gas, and provide qualified raw materials for subsequent production.
