Key Features and Application Advantages
The "350y" designation refers to its theoretical tray equivalent per meter, balancing separation efficiency and pressure drop—350 y units indicate it meets medium-to-high separation requirements, critical for formaldehyde purification. Made from 90% alumina ceramic, it exhibits exceptional corrosion resistance to formaldehyde and acidic byproducts, withstanding temperatures up to 1200°C. Its 350 m²/m³ specific surface area and 2.5-3 mm pore size ensure rapid vapor-liquid contact, reducing the number of theoretical stages needed. In formaldehyde distillation, this packing lowers column height by 15-20% compared to traditional metal or plastic packings, while maintaining stable operating pressure drops (<200 Pa/m) and a service life exceeding 10 years.
FAQ:
Q1: What makes 350y ceramic packing suitable for formaldehyde distillation?
A1: Its ceramic composition resists formaldehyde-induced corrosion, and the structured corrugation ensures high mass transfer efficiency, critical for separating formaldehyde from water and organic impurities.
Q2: How does the 350y specification impact distillation performance?
A2: 350y balances efficiency and pressure drop, delivering 350 theoretical stages per meter—ideal for formaldehyde processes where precise separation of formaldehyde from methanol and formic acid is required.
Q3: Can this packing be retrofitted into existing distillation columns?
A3: Yes, it fits standard column diameters with minimal modification, offering lower capital costs than full column replacement while enhancing separation performance.
