Structured packing for separation in tower
Structured packing is a kind of filler which at uniform geometry arranged and neatly piled in the tower. It is widely used in many fields for large surface area, low pressure drop, uniform fluids, heat and mass transfer efficiency and other advantages.
For example, structured packing is used for extraction column, and the column will be used for extraction of aromatics from oil by a solvent.
Our structured packing with knitted, perforated and expanded types covers corrugated grid packing, expanded metal prick corrugated plate packing, metal perforated plate corrugated packing, wire gauze structured packing, woven structured packing and sheet metal packing. It can be designed in alkali resistance and acid resistance materials. Our products are well accepted by overseas customers. Structured packings is widely used in spices, pesticides, fine chemical, laboratory, petrochemical and other fields.
Knitted structured packing is made from multiple strands of fine wire that are knitted together in a tubular pattern and then crimped and coiled or layered to provide a three dimensional structure of peak and valleys. The multi-strand fine wire provides a high surface area. This structured packing is suited for applications that demand high separation efficiency with a lower pressure drop, such as, high purity product distillations and solvent and byproduct recovery.
Woven Structured Packing is manufactured from specially woven wire gauze that is pressed into smooth plates, uniformly perforated, corrugated and stacked with corrugations in alternate directions. This construction promotes intimate gas/liquid contact. The woven structured packing with of high separation efficiency, is used in pharmaceuticals and fine chemicals.
Metal Perforated Plate Corrugated Packing is made from perforated plate with channel corrugation on surface. It is formed from vertical sheets of corrugated metal with the angle of the corrugation reversed in adjacent sheets to form an open structure with inclined flow channel. The packing has advantages such as high capacity, low resistance, high mass-transfer efficiency and strong resistance to fouling. It is widely used in unit operations like rectification, absorption and extraction.
Laboratory Structured Packing is used in small Laboratory columns ranging from 50mm to 80mm in diameter.
Knitted structured packing with multi-strand fine wire provides a high surface area and high separation efficiency. All sizes knitted structured packing is offered.
Expanded metal prick corrugated plate packing is suitable for fields requiring high degree separation such as industry of fine chemicals, solvent recovery and chemical product refining, etc.
