Plastic structured packing
lastic perforated plate corrugated packing
The plastic structured packing is widely used in the process of adsorption, desorption, waste gas purification and heat transfer. It is suitable for the process of large liquid load and high operating pressure. It is in the material of PP, PVC, PVDF, and the temperature resistance for PVDF is up to 150℃.
It is mainly used in separation of oil and water in oil field and refinery. It has the advantages of light weight, mass transfer rate, large specific surface area, and easy change.
