Metal corrugated structured packing is a critical tower internal, widely used in chemical, petrochemical, and environmental engineering for efficient gas-liquid mass transfer. Its "quota" or specifications determine performance, including material, size, and structural parameters.
Material options include stainless steel 304, 316L, and nickel-based alloys, selected based on corrosion resistance and operating temperature. Size specifications cover column diameters (from small lab-scale to large industrial towers) and packing height, ensuring compatibility with existing tower designs.
Key performance parameters in the quota are specific surface area (typically 100-500 m²/m³) and porosity (0.8-0.95). A higher specific surface area enhances mass transfer efficiency, while optimal porosity ensures low pressure drop. The "theoretical number of plates" (NTS) is also specified, reflecting separation performance.
When selecting, factors like process requirements (distillation, absorption), operating conditions (temperature, pressure, liquid/vapor load), and separation purity must align with the packing quota. Its advantages include high efficiency, stable operation, and easy cleaning, making it a preferred choice for modern tower internals.
