Sheet metal packing gets greater surface area per cubic foot than random packing of equal capacity. A series of perforated vertical corrugated layers make up each packing element. Gas/liquid is spread and distributed radially from layer to layer within the element. Surface texturing on the sheet metal further enhances wettability and mass transfer. Installed in opposing 90°-rotated sections, these elements promote thorough mixing and even gas/liquid distribution across the radius of the tower. Wiper bands throughout the packing prevent fluid from migrating between the packing and vessel wall.

Specification

• Material: SS 304, SS 304L, SS 316, SS 316L, etc.
• Specific surface areas: 125 m²/m³, 175 m²/m³, 200 m²/m³, 250 m²/m³, 300 m²/m³, 350 m²/m³, 500 m²/m³.

Features

• Its high mass transfer surface area is suitable for close boiling components distillation due to shorter columns.
• Its structured arrangement ensures no channeling of liquid and requires minimum liquid redistribution.
• Due to its very low pressure drop, it is recommended for vacuum distillation systems.
• It has higher vapour load capacity as compared to random packing and trays.
• It provides low liquid hold-up.

Application

• Refinery columns (atmospheric and under vacuum).
• Petrochemical columns.
• Natural gas glycol dehydration.
• Wastewater treatment stripping columns.
• Atmospheric pressure and high pressure columns.
