Structured Packing
FLEXERAMIC® Ceramic Structured Packing
Our geometrically arranged corrugated sheets provide greater resistance to fouling than random packing, while our design provides high capacity, higher efficiency and lower pressure drop than any random packing and most trays that are available today.
Revamp existing packed or tray columns with structured packing from Knight Material Technologies offers an economical alternative to other media. FLEXERAMIC® structured packing affords plant operators increased separation efficiency and operation capacity, lower pressure drop and often significantly lower energy costs for distillation or absorption operations.
Competitive Advantages
- Made in America
- FLEXERAMIC® structured packing can process 30% more gas flow than ceramic saddles (random packing)
- 30% more gas flow results in 30% more acid production
- 50% lower pressure drop as compared to ceramic saddles (random packing) with the same gas flow
- Benefit is 50% energy savings
Capabilities
- Proper mixing throughout the entire chamber
- Reduced channeling of liquid and vapor, providing more effective contact of acid and gas
- Vertically oriented ceramic corrugated sheets reduce resistance to fluid flow
- Hundreds of installations; >100 in sulfuric acid alone
- Excellent resistance to fouling
