550y ceramic structured packing is a specialized high-performance ceramic packing designed for efficient butanol separation. Its unique regular, ordered structure ensures superior gas-liquid contact, making it a critical choice for separating butanol from fermentation broths, reaction mixtures, or azeotropic systems in chemical distillation processes. With excellent chemical stability and mechanical strength, it addresses the challenges of butanol separation, such as high purity requirements and harsh operating conditions.

Structural Design and Performance Advantages of 550y Ceramic Structured Packing
The 550y designation refers to its specific surface area of 550 m²/m³, a key parameter that defines its separation efficiency. The packing features a regular wave-like arrangement of ceramic sheets, creating uniform flow channels that minimize channeling and maximize contact between vapor and liquid phases. This structured design significantly increases the number of theoretical plates (typically 5-8 plates/m) while maintaining low pressure drop (often <100 Pa/m), outperforming traditional random ceramic or metal packings. Chemically, ceramics exhibit exceptional resistance to organic solvents like butanol, acids, and alkalis, ensuring long-term stability without degradation. For butanol separation, this translates to higher product purity (>99.8%), reduced energy consumption, and extended service life, making it ideal for both batch and continuous production processes.
Product Line and Industrial Applications of 550y Ceramic Structured Packing
Our 550y ceramic structured packing is available in standard sizes (e.g., 100×100×2500 mm) and customizable dimensions to fit various column diameters and heights. It is widely applied in biobutanol and petrochemical production plants, where it replaces inefficient distillation columns or random packings. For instance, a major biobutanol manufacturer in Asia reported a 20% improvement in separation efficiency and a 12% reduction in reboiler duty after installing 550y packing in their 10,000-ton/year production line. Additionally, it is used in small-scale laboratories for butanol purification research, thanks to its precise structure and reproducible performance.
FAQ:
Q1: What makes 550y ceramic structured packing suitable for butanol separation specifically?
A1: Its 550 m²/m³ specific surface area and regular wave structure enable efficient mass transfer, while ceramic material resists butanol-induced corrosion, ensuring stable and high-purity separation.
Q2: How does 550y packing compare with metal structured packing in butanol separation?
A2: Ceramics offer better corrosion resistance for organic solvents, lower thermal conductivity (reducing heat loss), and lower initial cost, though metal may have higher mechanical strength for high-pressure systems.
Q3: What operating conditions are recommended for 550y ceramic packing in butanol distillation?
A3: Typically operated at temperatures 100-150°C, pressures 1-3 bar, and liquid/vapor rates 0.5-2 m³/(m²·h), with proper pre-treatment of feed to prevent ceramic abrasion.
