Wire mesh packing and plate structured packing are two common tower internals in separation processes, each with distinct characteristics. Wire mesh packing consists of metal or plastic wire mesh formed into regular corrugated sheets, creating a high specific surface area (typically 350-500 m²/m³). Its fine, interconnected structure ensures excellent mass transfer efficiency, making it ideal for precise separations like pharmaceutical and fine chemical distillation. However, it has lower mechanical strength, making it less suitable for high-pressure or high-solid-content applications.

Plate structured packing, by contrast, uses metal or plastic plate sheets stamped into uniform wave patterns, resulting in a specific surface area of 250-400 m²/m³. Its rigid, continuous structure offers higher flux and lower pressure drop, enhancing handling capacity for viscous or fouling-prone fluids, such as in petroleum refining or environmental treatment. Though its mass transfer efficiency is slightly lower than wire mesh, its robustness and scalability make it a preferred choice for large-scale industrial towers.

The core differences lie in structure, efficiency, and application. Wire mesh excels in precision separations with its high surface area, while plate packing is better for high-throughput, viscous, or fouling services due to its durability and lower pressure drop. Understanding these distinctions helps select the optimal packing for specific process requirements.
