Wire mesh corrugated packing  is an important milestone in the development of structured packing. This packing is composed of corrugated wire mesh sheets arranged at an angle of 30° or 45°. The two adjacent corrugated sheets are in opposite directions. When filling in the tower, the upper and lower plates of packing are stacked at 90°. It has the advantages of high efficiency, low pressure drop and large flux. The products include BX and CY types, which are often used in vacuum distillation, atmospheric distillation and suction processes of difficult-to-separate and heat-sensitive systems.

The punctured corrugated packing  is a regular packing made by first rolling out small puncture holes with high density on metal sheets and then pressing them into corrugated sheets. Due to the special punctured microporous structure on the surface, the wetting performance of the packing is improved and the performance of the metal wire mesh corrugated packing can be maintained.

Orifice plate corrugated packing  is a regular packing assembled from holes, small rolled lines and large corrugations on the surface of metal sheets. It has the characteristics of small resistance, uniform gas-liquid distribution, high efficiency, large flux and unobvious amplification effect. It is used in negative pressure, normal pressure and pressurized operations.

High-efficiency structured packing products include: wire mesh corrugated packing, strong wire mesh corrugated packing, mesh corrugated packing, perforated plate corrugated packing, and calendered perforated plate corrugated packing.

Stainless steel corrugated packing can be divided into mesh corrugated packing, wire mesh corrugated packing, perforated plate corrugated packing, rolled perforated plate corrugated packing, etc. 

Stainless steel corrugated packing (BX500, CY700, CY900, CY1000). Stainless steel perforated plate corrugated packing (SM250, SM350, SM450, SM550 and 250Y, 350Y, 450Y, 550Y). Stainless steel mesh plate corrugated packing (SW-1, SW-2), etc.

The main materials are: stainless steel 304, 304L, 316, 316L, 310/310S, 321, 2250/2507, copper, aluminum, pure titanium, molybdenum titanium, monel, Hastelloy, Inconel, copper-nickel alloy wire, nickel alloy and other stainless steel materials

The main advantages of stainless steel corrugated packing: large specific surface area, high porosity, light weight, high packing efficiency; small gas phase passage inclination, regular gas phase passage, small pressure loss, low packing pressure drop; good radial diffusion and sufficient gas-liquid contact.

Stainless steel corrugated packing is assembled from stainless steel wire mesh corrugated sheets. The packing forms a uniform geometric pattern arrangement in the tower, which stipulates the gas-liquid flow path and improves the channel flow and wall flow phenomenon. Due to the unique capillary effect of the wire mesh, the surface area has more effective wetting performance, low pressure drop and less liquid holdup, so it has a high separation efficiency. It is especially suitable for difficult-to-separate systems and heat-sensitive systems.

It is widely used in petrochemical industry, such as catalytic cracking and distillation section of refinery, fertilizer, natural gas, biochemical industry, environmental engineering and other fields. The tower equipment has a diameter of 3 meters and the separation performance is higher than that of stainless steel perforated plate corrugated packing. It can be used for operating temperature below 400℃, and there is no temperature limit for low temperature operation.

BX-500 stainless steel wire mesh corrugated packing is particularly suitable for vacuum distillation of heat-sensitive and difficult-to-separate systems, especially for operating pressures below 7KPa, and for conditions requiring more theoretical plates and lower pressure drop; low total height; test towers set up for industrial amplification; small liquid holdup; and where the humidity of the heating medium is limited.

CY-700 stainless steel wire mesh corrugated packing is generally used for isotope separation or precision fractionation of difficult-to-separate systems that require a large number of theoretical plates. It can also be used in situations where the height is strictly limited or high-purity products are required. For example: nitrotoluene, isopropanol, ethylene oxide, methanol, ethanol, turpentine, C5-C9 synthetic fatty acids, sandalwood and many other petrochemical, fragrance, pharmaceutical, and dye products.

CY-900 stainless steel wire mesh corrugated packing is generally used for isotope separation or precision fractionation of difficult-to-separate systems that require a large number of theoretical plates. It can also be used in situations where the height is strictly limited or high-purity products are required. For example: nitrotoluene, isopropanol, ethylene oxide, methanol, ethanol, turpentine, C5-C9 synthetic fatty acids, sandalwood and many other petrochemical, fragrance, pharmaceutical, and dye products.

CY-1000 stainless steel wire mesh corrugated packing is generally used for isotope separation or precision fractionation of difficult-to-separate systems that require a large number of theoretical plates.

The types of wire mesh corrugated packing are divided into: wire mesh corrugated packing, punctured corrugated packing, and perforated plate corrugated packing.

1.Wire mesh corrugated packing is an important milestone in the development of structured packing. This packing is composed of corrugated wire mesh sheets arranged at an angle of 30° or 45°. The two adjacent corrugated sheets are in opposite directions. When filling in the tower, the upper and lower plates of packing are stacked at 90°. It has the advantages of high efficiency, low pressure drop and large flux.

2. Punctured corrugated packing is a regular packing made by rolling out small puncture holes with high density on metal sheets and then pressing them into corrugated sheets. Due to the special punctured microporous structure on the surface, the wetting performance of the packing is improved and the performance of the metal wire mesh corrugated packing can be maintained.

3. Orifice plate corrugated packing is a regular packing assembled from holes, small rolled lines and large corrugations on the surface of metal sheets.

It is used in negative pressure, normal pressure and pressurized operations.

Wire mesh packing is the main form of mesh corrugated packing, which is made of metal wire mesh. Wire mesh packing is a high-efficiency packing widely used at home and abroad. It is a disc-shaped regular packing composed of vertically arranged corrugated mesh sheets. The inclination angle between the corrugation peak height and the tower axis is 45o and 30o, and it is divided into two types: CY and BX.

Features of wire mesh packing: The wire mesh packing has a compact structure, low resistance, high mass transfer efficiency, large processing capacity, and large specific surface area. The disadvantages of wire mesh packing are that it is not suitable for processing materials with high viscosity, easy to aggregate, or with suspended matter, and it is difficult to load and unload and clean up, and the cost is high.

Wire mesh filler has the following characteristics:

1. High theoretical plate number, large flux and reduced pressure;

2. Good low-load performance, the number of theoretical plates increases with the decrease of gas load, and there is almost no low-load limit;

3. Great operational flexibility;

4. The amplification effect is not obvious;

5. Able to meet the requirements of precision, large-scale, high vacuum distillation equipment.

Types, models and characteristics of wire mesh fillers: - Anping County Maoqun Wire Mesh Manufacturing Co., Ltd.

X-250: precision distillation with high production intensity and low number of theoretical plates;

X-500: vacuum distillation of heat-sensitive and difficult-to-separate special series, especially vacuum distillation with pressure less than 7KPa.

Y-700: Separation of isotopic mixtures and isomeric mixtures.

Application of wire mesh packing: Wire mesh packing has low pressure drop and high separation efficiency. It is particularly suitable for precision distillation, vacuum distillation equipment and distillation separation of high-purity products. It provides an effective means for the distillation of difficult-to-separate systems and heat-sensitive systems. Although it is expensive, it is still widely used due to its excellent performance.
