Structured Packing: Optimized Mass Transfer and Separation

Structured packing is a special material used to fill packed columns. Based on its unique structure, it increases the contact surface area between gas and liquid, to achieve more efficient mass and heat transfer, and accelerate the processes of mass transfer, heat transfer, absorption and desorption. It is widely used in the fields of chemical, petroleum, and environmental protection to achieve the purpose of various gas-liquid treatments and provide efficient and reliable solutions for projects.

It is divided into X-type and Y-type by corrugation angle. The X-type represents a 30° angle, while the Y-type represents a 45° angle. X-type structured packing exhibits lower pressure drop, while Y-type structured packing offers better mass transfer performance.

Structured packing is divided into perforated plate corrugated packing and wire mesh corrugated packing by structure.

Perforated plate corrugated packing surface has special texture and perforated holes

Perforated Plate Corrugated Packing

It is a versatile structured packing, composed of several corrugated parallel and vertically arranged metal corrugated sheets. These sheets are perforated with a special texture on the surface to improve the specific surface area for effective mass transfer. It is widely used in petrochemical, natural gas purification, metallurgy and other industries.

Wire mesh corrugated packing

Wire Mesh Corrugated Packing

It is disk-shaped structure packing consisting of various vertically arranged corrugated wire mesh strips. Its geometric structure and unique capillary effect makes it has a very high specific surface area and separation efficiency.

  • Uniform gas-liquid distribution, small liquid holding capacity.
  • Corrosion resistance, high temperature resistance, high separation and filtration efficiency.
  • Low pressure drop and reduced liquid retention.
  • Non-obvious amplification effect, flexible operation.

It is often used in chemical, petroleum, refining, metallurgy and other industrial fields for improving mass transfer efficiency, separating substances, reducing gas pressure drop and other key process operations.
