Large Specific surface Area Metal Structured Packings
Product Description
(1) Metal Wire Gauze Packing (Sulzer Packing)
A. Product characteristics:
1. Large specific surface area, high void ratio and light.
2. Obliquity of gas passage is small and regular, so pressure drop is low.
3. Good radial diffusion and sufficient gas contact.
(2)Application fields:
1. 250(AX) Precision rectification for high productive capacity and less theoretical plate number.
2. 500(BX) Vacuum rectification for thermosensitive system and hard separation system, especially suitable for rectification with pressure lower than 7KPa.
3. 700(CY) Separation of isotopic compound and isomeric compound.
Metal Perforated Plate Corrugated Packing
Product characteristics:
The packing is made from perforated plate with channel corrugation on surface, and remains structure feature of metal wire gauze packing. It strengthens uniform liquid distribution and surface wetting ability, which increases mass transfer efficiency. The unit height is 50-200mm per coil, and the packing is prepared in blocks when diameter is larger than 1. 5m.
Application fields:
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. According to packing types, the applicable minimal tower diameter is 80-200mm while Max. tower diameter reaches 13m, liquid spray density ranges from 0. 2 to 200m3/(m2. H) and pressure ranges from vacuum to high pressure. For these reasons it is a type of all-purpose efficient structured packing suitable for chemical industry, chemical fertilizer industry, oil refining, petrochemical industry, etc.
3. Expanded metal prick corrugated plate packing
A. Product characteristics:
Metal sheet is perforated 70 very small holes with thorn per square centimeter, then is pushed to corrugated sheet, finally it is assembled to coil. Because the wetting ability increases, it still has the excellent separation performance of wire gauze packing when liquid flow is large.
Application fields:
Suitable for fields requiring high degree separation such as industry of fine chemicals, solvent recovery and chemical product refining, etc.
4. Metal Plate-net Corrugated Packing
A. Product characteristics:
A appropriately treated thin metal band is drawn to diamond gauze plate with appointed specification, which cuts down the complex procedures of drawing wire and knitting mesh, while the packing still has the excellent wetting ability and separation performance of wire gauze packing.
C. Application fields:
1. Atmospheric rectification and vacuum rectification, application fields similar to metal wire gauze packing and special technology such as requiring titanium or aluminum gauze packing.
2. Substituting for random packing and revamping some tray towers in appropriate conditions.
3. Absorption requiring low resistance and distillation with heat pump.
