Metal wire gauze corrugated structured packing is a key component in modern separation processes, particularly in distillation, absorption, and stripping columns. Its design and material properties contribute to efficient mass and heat transfer, making it suitable for a wide range of industrial applications.
Metal wire gauze structured packing consists of thin, corrugated metal sheets, typically made from stainless steel, brass, or other alloys, woven into a fine mesh. The corrugations are arranged at specific angles (usually 30°–45°) to create a regular geometry that promotes uniform vapor-liquid distribution. The high surface area-to-volume ratio, often ranging from 250 m²/m³ to 750 m²/m³, enhances interfacial contact between phases.
The wire gauze material is characterized by its porosity and capillary effect, which improves liquid dispersion and film formation. This design reduces channeling and promotes efficient phase interaction.
The performance of metal wire gauze structured packing is often evaluated in terms of height equivalent to a theoretical plate (HETP), pressure drop, and operational capacity. Typical HETP values range from 100 mm to 300 mm, depending on the system conditions and packing geometry. The pressure drop per theoretical stage is generally low, often between 0.1 and 0.5 mbar, contributing to energy efficiency.
Its high separation efficiency is particularly beneficial in applications requiring precise fractionation, such as in the pharmaceutical, petrochemical, and fine chemical industries. The packing is also suitable for vacuum distillation due to its low pressure drop characteristics.
Metal wire gauze structured packing is commonly used in:
Distillation columns for high-purity separation
Absorption towers for gas treatment
Stripping operations in environmental engineering
Heat-sensitive processes under vacuum conditions
