Ceramic structured packing 125y is a specialized, high-performance packing designed for high-temperature distillation columns. Composed of high-purity alumina (Al₂O₃) with a regular wave structure, it offers superior mass transfer efficiency, thermal stability, and corrosion resistance, making it critical for industrial separation processes under extreme temperature conditions.

Key Features and Application of Ceramic Structured Packing 125y
The 125y designation specifies its geometric parameters, with a surface area of 125 m²/m³ and optimized wave angles/pitch for balanced separation. Made from 95% pure alumina, it withstands temperatures up to 1200°C, ensuring structural integrity during thermal cycling. Its ordered packing structure minimizes pressure drop while enhancing HETP (height equivalent to a theoretical plate), outperforming random packing in efficiency. In high-temperature distillation, it is widely used in petrochemical, coal chemical, and fine chemical industries—for example, separating hydrogen/nitrogen in ammonia synthesis, purifying high-boiling organic compounds, or handling corrosive streams like sulfuric acid. Its 50 MPa compressive strength ensures long service life, reducing maintenance needs.
FAQ:
Q1: What is the maximum operating temperature of ceramic structured packing 125y?
A1: Up to 1200°C, thanks to the high-purity alumina material and stable crystalline structure that resists thermal degradation.
Q2: How does 125y compare to 100y or 150y models?
A2: 125y balances efficiency and pressure drop, with 125 m²/m³ surface area—higher than 100y (100 m²/m³) and lower pressure drop than 150y (150 m²/m³), ideal for medium-high separation requirements.
Q3: Is it suitable for corrosive environments?
A3: Yes, 95% alumina ceramics resist acids, alkalis, and organic solvents, making it compatible with corrosive high-temperature distillation streams.
