Lead-Free Corrugated Packing is a specialized structured packing designed for environmentally sensitive chemical processes. Unlike traditional packing containing lead, it eliminates heavy metal risks, ensuring compliance with strict environmental regulations while maintaining high efficiency in industrial separations like distillation and absorption. This innovative solution balances performance and sustainability, making it indispensable in industries prioritizing green manufacturing.

Key Features and Material Advantages
Crafted from lead-free, corrosion-resistant materials such as polypropylene (PP), polytetrafluoroethylene (PTFE), or 316L stainless steel, this packing offers exceptional chemical inertness and mechanical durability. Its precise corrugated geometry—with controlled angles and spacing—maximizes specific surface area (typically 150-350 m²/m³) while minimizing pressure drop, boosting mass transfer efficiency. In pharmaceutical solvent recovery, for example, it reduces byproducts by 20% and ensures distillate lead levels below 5 ppb, meeting FDA and EPA ultra-purity standards. The modular design allows easy installation and maintenance, adapting to diverse column sizes from lab-scale to large industrial systems.
FAQ:
Q1: Is lead-free corrugated packing suitable for high-temperature processes?
A1: Yes, PTFE and stainless steel variants withstand temperatures up to 260°C, ideal for distillation and evaporation in thermal-sensitive applications.
Q2: How does it compare to traditional random packing in efficiency?
A2: It enhances separation efficiency by 15-20% due to optimized surface area and reduced channeling, lowering energy consumption by minimizing pressure loss.
Q3: Does it comply with REACH and RoHS environmental directives?
A3: Absolutely, as lead-free and non-toxic, it meets REACH restrictions on hazardous substances and RoHS compliance for electronic/chemical manufacturing.
