The "125y" designation refers to a precise corrugation pattern, typically with a specific surface area of ~125 m²/m³ and a void fraction of 85-90%. This design ensures minimal pressure drop (often <200 Pa/m at standard flow rates) and enhanced gas-liquid contact, critical for efficient mass transfer in distillation or absorption systems. Made from high-purity alumina ceramics, it exhibits exceptional chemical inertness—resisting attack from chlorinated solvents, which are highly reactive and can degrade plastic or metal materials. Additionally, the ceramic matrix offers excellent thermal stability, withstanding temperatures up to 800°C, making it suitable for high-temperature separation processes. In chlorinated solvent recovery, 125y packing is widely applied in scenarios such as pharmaceutical intermediate production (recovering solvents like 1,1,1-trichloroethane), electronic component cleaning (recycling trichloroethylene), and petrochemical byproduct processing (separating dichloromethane from wastewater). Its ability to maintain separation efficiency over extended periods reduces the need for frequent replacements, lowering lifecycle costs.

Q1: What are the core performance parameters of 125y ceramic structured packing?
A1: Specific surface area ~125 m²/m³, void fraction 85-90%, pressure drop <200 Pa/m, and maximum operating temperature up to 800°C.
Q2: How does 125y ceramic packing compare to plastic or metal alternatives for chlorinated solvent recovery?
A2: It offers superior chemical resistance (no degradation from chlorinated solvents), longer service life (5-8 years vs. 2-3 years for plastics/metals), and lower maintenance needs due to minimal wear.
Q3: Can 125y packing be tailored for custom chlorinated solvent recovery systems?
A3: Yes, it is available in various sizes, packing heights, and ceramic grades (e.g., alumina-silica), ensuring compatibility with different column dimensions and solvent properties for optimal efficiency.
