Key Features and Product Introduction
The "350y" designation refers to its specific surface area of 350 m²/m³, a balance that maximizes mass and heat transfer without excessive pressure drop. Crafted from high-purity alumina ceramic, it exhibits exceptional resistance to sulfuric acid (H₂SO₄) corrosion, even at elevated temperatures up to 800°C, while maintaining structural integrity. The structured packing features a regular corrugated configuration, creating uniform flow channels that promote efficient gas-liquid contact. This design minimizes channeling and dead zones, leading to superior separation efficiency—critical for sulfuric acid plants where strict purity standards (98-99.9% H₂SO₄) must be met. In applications like drying towers and absorption towers, 350y ceramic packing effectively removes acid mist and impurities, ensuring the clean, dry gas needed for downstream conversion processes, ultimately boosting the overall yield and quality of sulfuric acid.
FAQ:
Q1: Why is 350y ceramic structured packing preferred over random packing in sulfuric acid plants?
A1: Its regular, ordered structure ensures uniform fluid distribution, reducing pressure drop by 30-40% compared to random packing while improving separation efficiency by 15-20%.
Q2: How does the ceramic material enhance the packing's performance in sulfuric acid environments?
A2: High-alumina ceramic (≥90% Al₂O₃) provides chemical inertness, resisting degradation from concentrated sulfuric acid and hot process conditions.
Q3: What maintenance requirements are needed for 350y ceramic structured packing in sulfuric acid plants?
A3: Minimal maintenance is needed, as the material resists fouling and erosion. Regular visual inspections for cracks or damage (common in high-velocity sections) are recommended to ensure long-term performance.
