Design and Performance Characteristics
Comprising high-purity ceramic materials (typically alumina or silica-based), 350y structured packing features a geometric architecture with a specific surface area of ~350 m²/m³. The "350y" designation denotes 350 corrugated waves per meter, ensuring uniform fluid distribution and minimal channeling—key to stable, consistent performance. Its ceramic composition endows exceptional corrosion resistance against phosphoric acid (H₃PO₄), a highly reactive medium in production, while thermal stability withstands process temperature fluctuations. Mechanically robust, it resists abrasion from solid particles in feedstocks, extending equipment lifespan.
In phosphoric acid manufacturing, 350y packing is deployed in critical stages like solvent extraction and purification. During wet process phosphoric acid (WPA) production, it replaces traditional random packing in columns, enabling precise contact between acid solutions and organic solvents (e.g., tributyl phosphate) for impurity removal. This configuration boosts extraction yields by 15-20% while reducing solvent carryover. In downstream gas absorption, it facilitates efficient separation of volatile components, ensuring the final product meets strict quality benchmarks with low metal ion contamination.
Key Advantages for Phosphoric Acid Producers
The adoption of 350y ceramic structured packing delivers multifaceted benefits. It reduces column size requirements by 25-30%, lowering capital expenditure and footprint. Its low pressure drop (typically <25 Pa/m) minimizes energy consumption for pumping, cutting operational costs by 10-15%. Chemical inertness eliminates frequent packing replacement, reducing maintenance downtime by 40% and extending service life to 8+ years. Consistently high传质效率 (theoretical plates ~1.2 per meter) ensures stable production output, critical for meeting market demand fluctuations.
