Structural Design and Material Advantages of 550y Ceramic Packing
The "550y" designation refers to the packing's specific surface area, measuring 550 m²/m³, which significantly improves mass transfer efficiency compared to traditional random packings. Constructed from high-purity alumina ceramics, this packing exhibits exceptional properties: high thermal shock resistance (withstanding temperatures up to 1200°C), excellent chemical inertness against phenol and other organic solvents, and robust mechanical strength to withstand operational pressures. Its uniform, regular channel structure minimizes dead spaces and reduces pressure drop, allowing for smoother gas-liquid contact and faster separation rates. In phenol separation applications, the packing's tight packing density and optimized void fraction (typically 0.75-0.8) ensure a theoretical plate count of 3-5 plates per meter, far exceeding conventional methods. This design makes it ideal for separating phenol from complex mixtures like coal tar, reformate oils, and synthetic reaction products, where precision and efficiency are critical.
