Stainless Steel 304L Knitted Metal Stuctured Packing For Separation Tower
Knitted Metal Stuctured Packing Introduction
Metal wire gauze packing is which made by carbon steel,stainless steel or aluminum alloy materials.Due to the special produce technology,wire gauze packing have the advantages of thin thickness,big surface area,big free volume,so less resistance,high separation efficiency,big disposal performance.so it is especially suitable for vacuum rectification and precision rectification.
Knitted Metal Stuctured Packing Technical Specification
The specification is based on SS304 material:
| Model | void volume | Piece thick | Number per heaping | Weave height | Weave distance | Gear-shape angle | F-factor | Theoretical hetp |
| (%) | (mm) | (kg/m3) | (mm) | (mm) | φ | φ | (Piece/m) |
| 100Y | 87.5 | 2.5+/-0.5 | 460 | 30 | 50 | 80 | 3.5 | 1 |
| 125Y | 85 | 2.5+/-0.5 | 480 | 23 | 42 | 80 | 3 | 1-1.5 |
| 160Y | 84 | 2.2+/-0.5 | 500 | 17 | 30 | 80 | 2.8 | 1.5-2 |
| 250Y | 82 | 1.4+/-0.5 | 530 | 13 | 22 | 80 | 2.5 | 2-3 |
| 350Y | 80 | 1.2+/-0.5 | 580 | 9 | 15 | 80 | 2 | 3.5-4 |
| 450Y | 76 | 1+/-0.5 | 600 | 6 | 11 | 80 | 1.5-2 | 4-5 |
250(AX), Precision rectification for high productive capacity and less theoretical plate number.
500(BX), Vacuum rectification for thermosensitive system and hard separation system, especially suitable for rectification with pressure lower than 7Kpa.
700(CX), Separation of isotopic compound and isomeric compound.
Metal Structured Packing Material
Structured packing is a range of materials that are specially designed for use in distillation and absorption columns, as well as chemical reactors. They usually consist of thin corrugated metal plates or gauzes, designed to force fluids on complicated paths throughout the column. The design is intended to ultimately produce a large surface area for contact between different phases.
Structured packing is made from a variety of materials including corrugated sheets of perforated embossed metal, plastic, or wire gauze. The resulting product is an open honeycomb with inclined flow channels producing a high surface area coupled with a low gas flow resistance. Enhancements are often chosen to maximize liquid spreading which are ideal for applications with low pressure and irrigation rates.
