What Are the Different Types of Structured Packing for Specific Applications?

structured packing, a key tower internal, plays a vital role in chemical separation processes. Its design optimizes mass transfer and efficiency, making it indispensable in industries like petrochemicals and pharmaceuticals. Here are the main types and their specific applications. Metal structured packing, with high mechanical strength, suits high-temperature and high-pressure environments. Examples include metal孔板波纹 (metal orifice corrugated) and丝网波纹 (wire mesh corrugated) packing, ideal for refining and large-scale distillation towers where stability is critical. Wire mesh structured packing, featuring high specific surface area (150-500 m²/m³), offers low pressure drop and exceptional separation efficiency, making it perfect for fine separation tasks such as pharmaceutical purification and food-grade alcohol production. Plastic structured packing, corrosion-resistant and cost-effective, is widely used in acidic/alkaline environments, like water treatment towers and organic solvent recovery systems. Composite structured packing, combining metal and plastic advantages, addresses complex工况 (working conditions) with both high efficiency and chemical resistance, suitable for multi-component mixture separation in environmental protection projects. Understanding these types helps select the right structured packing for optimal tower performance.
