What Are the Design Principles of Structured Packing for High - Temperature Processes?

structured packing, a critical tower internal in high-temperature industrial processes, requires careful design to ensure optimal performance. Key principles include material selection—prioritizing high-temperature resistant materials like Inconel or alumina ceramics to prevent oxidation. Thermal stability design, such as using expanded metal or corrugated structures, minimizes deformation under heat. Wettability engineering, via surface modifications, ensures uniform liquid distribution. Pressure drop control, balancing efficiency and flow rate, is achieved through precise channel geometry. Mechanical strength, addressing thermal shock resistance, guarantees long-term reliability. These principles collectively enhance separation efficiency and extend service life in harsh high-temperature environments.
