Low Liquid Load Structured Packing For Distillation Columns For Absorption
Plastic wire gauze packings is made from admixture knit mesh of Polypropylene wire and Polyacrylonitrile wire, therefore it has good chemical stability. The packing is prepared in 150-250mm cylinders and should be fully filled on the tower section. The packing is corrosion resistant and light(only 120kg per cubic meter).
Technical data:
| Type | Material | Wire Size (mesh) | Peak (mm) | Obliquity (Degree) | Specific Surface Area (m2/m3) | Void Volume (m3/m3)
| Density (Kg/m3) |
| 500(BX) | PP/Polyacrylonitrile | 40 | 6.3 | 30 | 450 | 0.85 | 120 |
| 624 | PP/Nylon | 40 | 4.5 | 45 | 624 | 0.96 | 120 |
| 450 | PP/Nylon | 40 | 6.2 | 30 | 450 | 0.97 | 120 |
Feature:
1. Mihnimum pressure drop,typically 2-4 mbar/m
2. Self-wetting packing surface
3. Low liquid load
4. Large number of transfer unit per meter
5. Operating temperature up to 80 degree
Application:
The packing is suitable for absorbing process with pressure 0.1-100Kpa under normal temperature and countercurrent flow reclaiming process with low liquid spray loading e.g. purification of waste gas, etc. It is usually used in low temperature (lower than 80℃) to absorb NH3, HCl and SO2 or water soluble solvents like acetone, acrylonitrile, methanol, alcohol, methanal, etc, as well as in the absorption of strong off odor matter like amine, thioalcohol and so on. Consequently it has a good effect in environmental protection field.
