Structured packing

AWS supplies a complete range of structured packing. Structured packing offers a high separation efficiency in combination with a low pressure drop and is used in the field of distillation, absorption and liquid-liquid extraction. The standard metal sheet structured packing has a special surface structure and together with its regular arrangement it gives very reliable and excellent characteristics.
Wire mesh structured is particularly used in vacuum columns and for very low liquid loads. It has a very low pressure drop per theoretical stage which is created by the capillary effect of the wire mesh.

Structured packings are made out of corrugated sheets arranged in a crisscrossing relationship to create flow channels for the vapor phase. The intersections of the corrugated sheets create mixing points for the liquid and vapor phases. Wall wipers are utilized to prevent liquid and/or Vapor bypassing along the column wall. Rotating each structured packing layer about the column axis provides crossmixing and spreading of the vapor and liquid streams in all directions.

All types of AWS  structured packings are available in a variety of corrugation sizes, providing the versatility to optimize the packing configuration to best meet the efficiency, capacity and pressure drop requirements for any particular application.
