Metal structured packing is a highly efficient mass transfer component widely used in distillation, absorption, and stripping columns across industries such as petrochemicals, refining, gas processing, and environmental engineering. Compared to random packing and tray columns, structured packing offers superior performance in terms of efficiency, capacity, and pressure drop reduction.
Wangdu (Hebei) Chemical Engineering Co., LTD specializes in the design and manufacturing of high-quality metal structured packing. Our products are engineered to meet the demanding requirements of modern industrial processes, ensuring optimal performance and long-term reliability.
Structured packing consists of corrugated metal sheets arranged in a geometric pattern to create a large surface area for gas-liquid contact. Key design features include:
Corrugated Layers: Thin, perforated metal sheets with precise angles (typically 45° or 60°) to maximize interfacial area.
Surface Enhancements: Some designs incorporate textures, grooves, or micro-features to improve wetting and liquid distribution.
Material Selection: Available in stainless steel (304, 316, 316L), carbon steel, titanium, and specialty alloys for corrosion resistance.
Modular Construction: Packing elements are assembled in layers, allowing easy installation and customization for different column diameters.
This optimized structure ensures efficient phase contact while minimizing energy consumption.
The uniform flow distribution and large surface area enhance separation efficiency, often reducing required column height compared to trays or random packing.
Ideal for difficult separations with close boiling points.
The open structure allows high vapor/liquid throughput with minimal resistance, lowering energy costs.
Particularly beneficial in vacuum distillation and high-capacity applications.
Can handle higher flow rates than conventional trays without flooding.
Reduces column diameter requirements in new designs.
Metal construction withstands high temperatures, pressures, and corrosive environments.
Resistant to fouling and degradation compared to plastic alternatives.
Various corrugation angles and surface treatments can be selected based on process requirements.
Customizable for revamps of existing tray columns.
Standard choice for most distillation and absorption applications.
Available in different surface areas (e.g., 125Y, 250Y, 350Y) for varying efficiency needs.
Made from wire mesh for ultra-high efficiency in low-liquid-load applications.
Commonly used in cryogenic air separation and fine chemical distillation.
Some designs feature special surface treatments or hybrid structures for enhanced performance in challenging services.
Crude oil fractionation, vacuum distillation
Aromatics separation, ethylene oxide/ glycol production
Acid concentration (H2SO4, HNO3)
Solvent recovery, specialty chemical purification
CO2 and H2S removal in amine contactors
