Due to its Structural rule, uniformity and symmetry, the metal structured packing has stipulated the vapor liquid flow path, improved the channel flow and wall flow phenomenon, and has the advantages of small pressure drop, large flux, high diversion efficiency, etc. The metal structured packing has been widely used in towers in many fields such as fine chemical industry, petrochemical industry, fertilizer, etc.
Metal Strucutured Packing include metal corrugated plate packing,metal mesh corrugated packing/mmcp,metal gauze structured packing
Metal corrugated plate packing is an important milestone in the development of structured packing. The packing is made up of corrugated mesh sheets. The corrugated sheets are inclined at 30° or 45°. The adjacent corrugated sheets are opposite in direction and filled in the tower. When loading, the upper and lower plates are stacked at 90°. It has the advantages of high efficiency, reduced pressure and large flux. The products are often used in vacuum rectification, atmospheric distillation and suction processes for difficult separation and heat sensitive systems.
Metal corrugated plate packing is a structured packing which is assembled by pressing a thin metal plate and pressing a small puncture hole with a high density into a corrugated sheet. Due to the special puncture microporous structure on the surface, the wetting property of the packing is improved and the performance of the wire corrugated packing can be maintained. This packing combines the advantages of wire mesh and corrugated packing. Its performance is between the metal gauze structured packing and the random packing. Due to reasonable structure, high strength, low cost compared with wire mesh corrugated packing, good corrosion resistance, strong anti-pollution ability, low pressure and large flux, it is especially suitable for organic and normal vacuum and pollution of organic matter distillation. And suitable for atmospheric and pressurized countercurrent absorption processes. In the design of the new tower and the renovation of the old tower, it is used to replace the random packing such as Pall ring and some plate towers. Especially in the transformation of large-scale towers, there are obvious economic effects on improving the output and quality of products and reducing energy consumption.
