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:

| (%) | (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.
