Structured Column Packing Metal Wire Gauze For Distillation
Ss304 Ss316 Metal Structured Packing For Air Liquid Filter And Distillation Tower
1. Super Packing Mall Metal Structured Packing
This is a general type of packing, which is composed of several vertically arranged reticulated corrugated plates. Instead of welding, the metal wire gauze structured packings are fixed to the wall with nails or rings. Its structure can not only change the distribution of liquid, but also improve the transfer efficiency.
2.Below are the main types we usually make. Each type has two styles, different in the wave clination angle to the axis, 30 degrees (X style) and 45 degrees (Y style). For example, 250Y structured packing, each wave has a 45 degrees angle to the axis, and the neighboring plates' waves are vertical to each other. We can also help make other types such as 450, 252, 452, etc. as per customer request.

Structured Packing Advantage
- 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.
