Structural Design and Performance Characteristics
The 350y structured packing derives its name from a specific surface area of 350 m²/m³ and a wire gauze thickness of 0.15-0.2 mm, striking a balance between mass transfer efficiency and operational stability. Crafted from high-purity alumina ceramics, it exhibits excellent chemical resistance to acids, alkalis, and organic solvents, while its low thermal conductivity minimizes heat transfer to the packed bed. This reduces localized hot spots—critical for heat-sensitive materials—by slowing heat conduction, ensuring that temperatures remain within safe limits. In distillation columns, its uniform flow paths and precise packing density (350-400 kg/m³) create optimal vapor-liquid contact, boosting separation efficiency by 15-20% compared to traditional random packing, while lowering pressure drop by 30%, enhancing overall process economy.
FAQ:
Q1: Why is the 350y packing structure ideal for heat-sensitive materials?
A1: Its low thermal conductivity and uniform channel distribution minimize residence time and localized heating, preventing overexposure to high temperatures that cause degradation.
Q2: What applications benefit most from 350y ceramic structured packing?
A2: It is widely used in distillation, absorption, and drying processes for pharmaceuticals, food additives, and fragrances, where maintaining material stability is critical.
Q3: How does it compare to metal or plastic packing in terms of thermal performance?
A3: Ceramic’s lower thermal conductivity reduces heat transfer, unlike metal (high thermal conductivity) or plastic (poor heat resistance), making it superior for heat-sensitive separation tasks.
