Wire mesh corrugated packing mass transfer efficiency
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.

|tray tower||Random packing tower||Structured packing tower|
Allowable load factor F
|Pressure drop per theoretical stage / Pa||400-1067||120-240||1.3-106.7|
|HETP / m||0.6-1.2||0.45-1.5||0.1-0.75|
Lower pressure drop through the column
■Lower botoms temperature for heat sensitive systems
■Higher relative volatility for diﬃcult separations
■Lower energy consumption
■Reduced foaming tendency
Higher efficiency in the same tower height
■Large number of theoretical stages required
■Reduced reflux requirement
■Reduced vessel diameter
■Increased operating rates
Excellent liquid spreading characteristics
■Oﬀshore applications subject to permanent tilt and motion
Reduced liquid hold-up
■Smaller amounts of polymer inhibitor
Characteristics of packed tower:
Compared with plate column, packed column has certain advantages, especially in recent years, a variety of new and efficient packing has been developed, which has more prominent advantages and wider application range. Its specific characteristics are as follows:
1. The pressure drop is very low, which can be used in vacuum distillation and other operating systems with limited pressure drop.
2. With the development of new high efficiency packing, the production capacity (allowable gas velocity) and efficiency of packed tower are equal to or exceed those of plate column. Many units at home and abroad use new packing to transform plate column, which greatly improves production capacity and efficiency.
3. Flexible operation.
4. It can deal with foaming system.
5. General fillers are easy to be blocked by suspended solids in the liquid, while some grid fillers with large void fraction have self-cleaning effect under high gas velocity scouring, and are not easy to be blocked, and their heat transfer performance is better than that of baffles.
6. The material selection of fillers is wide, such as metal, plastic, ceramic, graphite, etc., which is suitable for wider chemical system and operating
