350y corrugated ceramic packing is a specialized structured packing designed for acetic acid distillation. Its 350y metric rating, corresponding to a specific surface area of approximately 1250-1500 m²/m³, ensures optimal gas-liquid contact, making it highly effective in separating acetic acid from water, organic impurities, and other byproducts in industrial distillation systems.

Key Features of 350y Corrugated Ceramic Packing
This packing is typically made from high-purity ceramics, such as cordierite or high-alumina materials, renowned for their excellent corrosion resistance to organic acids like acetic acid. Its unique corrugated structure, with a carefully optimized angle (usually 125° or 150°) and spacing between corrugations, minimizes channeling and maximizes mass transfer efficiency. The 350y rating balances surface area and porosity, resulting in a void fraction of around 0.85-0.9, which allows for high vapor and liquid flow rates while maintaining low pressure drop. Engineered through precision extrusion and high-temperature sintering, the packing exhibits high mechanical strength, enabling stable operation under varying pressure conditions (up to 10 bar) and temperatures (200-300°C), common in acetic acid distillation processes.
FAQ:
