SiC Structured Packing
Product Introduction
Porous silicon carbide materials feature high porosity, large specific surface area, a wide and controllable pore size range, favorable gas-liquid contact performance and excellent surface wettability. The novel porous silicon carbide packing delivers low pressure drop and high mass transfer efficiency, boasting broad industrial application prospects in rectification and separation processes.
Product Advantages
- Corrosion & High Temperature Resistance
Silicon carbide boasts stable chemical properties. It resists various oxidizing and reducing acids including hydrofluoric acid, sulfuric acid, nitric acid, hydrochloric acid and aqua regia, and is also alkali-resistant.
Our silicon carbide structured packing is fabricated via controlled reaction sintering at temperatures above 1400°C. Featuring outstanding high-temperature tolerance and non-combustibility, SiC packing ensures intrinsic safety and high-performance operation for chemical plant facilities.
- High Separation Efficiency
Silicon carbide materials possess relatively high surface energy, which endows them with both excellent lipophilicity (for non-polar molecules) and hydrophilicity (for polar molecules). Besides, the micro-filamentous or porous microstructure on their surface delivers favorable capillary action for uniform liquid dispersion and full surface wetting.
Benefiting from superior wettability and industry-standard high specific surface area (e.g., 250 m²/m³, 350 m²/m³, 500 m²/m³, 750 m²/m³), SiC packing achieves mass transfer efficiency equivalent to or even higher than metallic packing under certain working conditions.
The outstanding mass transfer performance of silicon carbide structured packing enables traditional corrosion-resistant internals made of plastic or ceramic to realize higher separation efficiency, eliminate process bottlenecks and optimize equipment footprint.
- Good Hydraulic Performance
Benefiting from the high mechanical strength of silicon carbide, the corrugated sheets of SiC packing can be manufactured into ultra-thin structures to deliver extremely high gas-liquid throughput. This high-throughput packing features low operating pressure drop and large processing capacity, which maintains high production output while ensuring superior separation efficiency.
The excellent hydraulic performance of silicon carbide packing enables traditional corrosion-resistant internals made of plastic or ceramic to achieve higher throughput, lower rectification pressure drop and smaller designed tower diameter.
