100y ceramic structured packing is a specialized high-performance packing material engineered for sulfur dioxide (SO₂) scrubbing, a critical process in industrial gas purification. Its unique structured design and robust ceramic composition make it indispensable for removing SO₂ from flue gases, ensuring compliance with environmental regulations and minimizing environmental impact.

Key Design and Performance Advantages of 100y Ceramic Structured Packing
The 100y designation reflects a precise engineering parameter, typically denoting a high specific surface area (e.g., 1m²/m³) and optimized pore structure, which significantly enhances gas-liquid contact efficiency. Unlike random packing, its ordered arrangement—featuring uniform, stacked metal or ceramic mesh sheets—eliminates channeling and dead zones, reducing pressure drop while maximizing mass transfer rates. Constructed from high-purity alumina or silica-based ceramics, it exhibits exceptional chemical resistance to sulfuric acid and other corrosive byproducts of SO₂ scrubbing, as well as high-temperature tolerance (up to 1200°C), making it suitable for harsh industrial environments like power plants, smelters, and chemical processing facilities.
Applications in Sulfur Dioxide Scrubbing Systems
In SO₂ scrubbing, 100y ceramic structured packing acts as the core component of absorption towers, where it facilitates the reaction between SO₂-laden gas and a liquid solvent (e.g., lime/limestone slurry). As the gas flows upward and the solvent flows downward through the packing, the large specific surface area of 100y packing ensures intimate contact, allowing SO₂ to dissolve into the solvent and form solid byproducts (e.g., calcium sulfite or sulfate). This process not only achieves SO₂ removal efficiencies of 95% or higher but also reduces operational costs by minimizing solvent usage and packing replacement frequency. Its durability ensures long-term stability, even in continuous high-volume industrial operations.
FAQ:
Q1: What distinguishes 100y ceramic structured packing from other packing types for SO₂ scrubbing?
A1: Its ordered, high-specific-surface-area design reduces pressure drop and enhances传质效率 (mass transfer efficiency) compared to random packing, while ceramic material provides superior corrosion resistance in acidic SO₂ environments.
Q2: Can 100y packing be used in both wet and dry SO₂ scrubbing systems?
A2: Primarily wet systems, as its structured design is optimized for liquid-gas contact. However, with proper maintenance, it can also adapt to low-moisture dry scrubbing setups, depending on system conditions.
Q3: How does the "100y" parameter affect performance?
A3: 100y typically refers to a specific surface area (e.g., 100 m²/m³) and pore size distribution, balancing efficiency and pressure drop. Higher values (e.g., 150y) offer more surface area but may increase pressure drop, while 100y strikes an optimal balance for most industrial applications.
