Standard Specification for Ceramic Regular Structured Packing

Ceramic regular structured packing is a critical tower internal in separation processes, offering high efficiency and stability. This article details the standard specification for such packing, covering material, structure, performance, and applications. Made of high-purity alumina ceramics, it has a melting point above 1700°C, excellent corrosion resistance to acids, alkalis, and organic solvents. Mechanical strength meets standards like 150 MPa flexural strength to withstand tower operating pressure and flow impacts. Regularly arranged with uniform channels, typically 50-300 A in channel width, providing a specific surface area of 100-500 m²/m³ and porosity of 70-85%. The geometric structure ensures optimal gas-liquid contact, reducing pressure drop while enhancing separation efficiency. Standard specifies separation efficiency ≥ 95% for binary mixtures with relative volatility > 1.5, pressure drop ≤ 200 Pa/m at 100 m³/h flow rate. Thermal shock resistance ensures stable operation in temperature fluctuations from -20°C to 600°C. Complies with industry standards such as GB/T 32495-2015 and ASTM D7399, with dimensional tolerance within ±2% and surface finish Ra ≤ 1.6 μm. Widely used in petrochemical fractionation towers, environmental protection absorption columns, and pharmaceutical distillation systems, it improves separation purity, reduces energy consumption, and extends tower service life. Adhering to the standard ensures reliable performance, making it an ideal choice for modern separation tower internals.
