1. DN1900 mm *200 mm distillation packing BX500 wire mesh type.
One customer ordered this product to use in his scrubber. He wanted to try to use it as kind of mist eliminator. We are also interested in its performance in this way.
2. BX500 type 200mm High Wire Mesh Structured Packing,
The mass transfer efficiency of wire mesh corrugated packing is directly determined by its specific surface area. According to the specific surface area, it can be divided into 250, 500 and 700 types. As the corrugated metal mesh filler belongs to the type of liquid membrane mass transfer, opening holes on corrugated filler sheet or making double-layer wire mesh filler to strengthen the uniform distribution of liquid on the corrugated wire mesh sheet, especially in low spray density, whether to ensure the uniform distribution of liquid on the wire mesh sheet is the key to maintain high separation efficiency.
3. Materials of BX500 type 200mm High Wire Mesh Structured Packing
The most common material used for Hualai structured column packing is SS 304 and SS 316L. However Hualai manufactures this solely based on our customers’ requirements and can also be made from other materials based on special requests. Other materials like Titanium, duplex 2205, copper, etc. are also no problem with us.
Uniform Liquid Distribution
In order to achieve even liquid distribution over the packing it is a must to have a good liquid distributor to maximize the interaction of the liquid and vapor. However if the packing height exceeds 3 meters we recommend using an intermediate liquid re-distributor as well for even flow.

①The data are based on 0.12mm wire, stainless steel material. Applicable temperature (-200—400)℃. 0.15mm and 0.17mm wire are also available.
②Metal wire mesh corrugated packing is suitable for clean gas-liquid system without solid particles or suspended solids or not easy to self-assemble.
Higher capacity
Reduced liquid hold-up
Excellent liquid spreading characteristics
Lower pressure drop through the column
Higher efficiency in the same tower height
6. Projects applying BX500 type 200mm High Wire Mesh Structured Packing,
7. Glycol Separation Train BX500 type 200mm High Wire Mesh Structured Packing
A three-column distillation train separates the glycols, namely MEG, DEG and TEG. For improved separation and to run at low temperatures, the columns are operated under vacuum. Yuanqiao structured packing as well as BX and CY wire gauze structured packing offer very high efficiency combined with low pressure drop. The benefits are lower bottom temperature, less product loss due to degradation, increased capacity and lower energy consumption.
