Ceramic corrugated packing is a new type of structured packing composed of many identical geometric packing units. Thanks to the unique structure of ceramic, it has excellent hydrophilic properties, which allows the formation of an extremely thin liquid film on its surface. The turbulent flow of the liquid film and the inclined and tortuous gas flow channels not only promote gas flow without obstructing it, enabling the ceramic packing to be comparable to metal packing, but also possess corrosion and high-temperature resistance properties that metal packing cannot match.
The surface structure has good wettability, which can accelerate liquid flow and minimize the liquid hold-up of the packing, thereby reducing the risks of overheating, polymerization, and coking. Ceramic corrugated packing consists of many similarly designed corrugated plates. When these corrugated plates are placed in parallel within a cylindrical tower, they are referred to as corrugated tower packing. This is a highly efficient packing, with a separation efficiency several times that of packed columns with the same void fraction. Compared with random tower packing, it offers lower pressure drop, larger operating flexibility, minimal scale-up effect, and maximum liquid handling capacity.
Currently, Ceramic Orifice Corrugated Packing is widely used across various industrial fields:
| Parameter Name | Specification | Remarks |
|---|---|---|
| Material | Cordierite, Mullite, Silicon Carbide, Aluminum Titanate | Customizable according to working conditions |
| Corrugation Angle | 30°, 45°, 60° | Optimized for low pressure drop and high efficiency |
| Void Fraction | 70%-90% | Uniform distribution, low flow resistance |
| Specific Surface Area | 100-500 m²/m³ | Adjustable based on corrugation size |
| Operating Temperature Range | -50℃ to 1200℃ | Depends on material type |
| Pressure Drop | 0.1-0.5 kPa/m | Under normal operating conditions |
| Separation Efficiency | 2-5 theoretical plates per meter | Higher than traditional random packing |
| Plate Thickness | 0.3-1.0 mm | Ensures strength and light weight |
| Tower Diameter Adaptation | 50 mm-10000 mm | Suitable for both laboratory and industrial towers |
| Corrosion Resistance | Resistant to strong acid, strong alkali, and organic solvents | Except for hydrofluoric acid (HF) |
