 Corrugated Sheet Metal Structured Packings

Description of Corrugated Sheet Metal Structured Packings  

Corrugated Sheet Metal Structured Packings is generally used in medium to small diameter columns for separations that require a maximum number of theoretical stages in the minimum column height. As there are many small spines due to surface pitting, the separation efficiency are improved with prolonged retention time on the surface and more sufficient exchange of vapor and liquid drop. The diameter of the filler hole is 0.4 ~ 0.5mm, which is usually made of ultra-low carbon corrosion resistant stainless steel material, used for oil industry, fine chemical industry, pharmaceutical equipment, etc.

Applications of Corrugated Sheet Metal Structured Packings  

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

 

Features of Corrugated Sheet Metal Structured Packings  

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.
