Metal corrugated packing is a vital type of tower internal widely used in chemical, petrochemical, and environmental engineering. Its unique structure and material selection endow it with distinct characteristics. Firstly, material diversity: typically made of stainless steel (304, 316), titanium, or nickel alloys, ensuring excellent corrosion resistance, especially suitable for harsh media like acids, alkalis, and high-temperature gases. Secondly, structural design: the corrugated sheets are arranged alternately at specific angles (e.g., 30°/45°), forming a uniform flow channel with high specific surface area (usually 100-500 m²/m³). This structure promotes efficient gas-liquid contact, reducing backmixing and enhancing mass transfer efficiency. Thirdly, performance advantages: low pressure drop, which minimizes energy consumption; high mechanical strength, allowing operation under high temperature (up to 600°C) and high pressure (over 10 MPa); and long service life, reducing maintenance costs. Additionally, its flexibility in size and configuration makes it adaptable to various tower diameters, from small lab-scale to large industrial columns. These characteristics make metal corrugated packing an ideal choice for distillation, absorption, and stripping processes, contributing significantly to the optimization of separation efficiency and equipment performance in industrial production.
