Neutralizing Corrosive Chemical Plumes
For chemical processing, electroplating, battery manufacturing, and semiconductor production, gaseous pollutants cannot be filtered via dry fabric media. Packed bed wet scrubbers provide an efficient, proven solution by transferring soluble gaseous pollutants into a neutralizing scrubbing liquid through high-surface-area mass transfer packing.
Key Design Parameters for High Absorption Efficiency
ADFC custom-engineers packed bed scrubbers in both vertical counter-current and horizontal cross-flow orientations tailored to specific acid gas profiles (HCl, HNO3, H2SO4, HF, Cl2, and NH3):
- Random vs Structured Packing: High-efficiency polypropylene, PVDF, or ceramic Tellerette and Tri-Pack rings maximize gas-liquid contact area with minimal static pressure drop.
- Automated pH & ORP Chemical Dosing: Continuous sensor loops automatically meter sodium hydroxide (NaOH) or sodium hypochlorite (NaOCl) into the recirculation sump to maintain optimal neutralization rates.
- High-Efficiency Chevron Mist Eliminators: Multi-pass blade profiles remove entrained chemical droplets down to 15 microns before exhaust through the clean-air stack.
- Corrosion-Proof Materials: Heavy-gauge UV-stabilized polypropylene (PP-H), PVDF, or vinyl ester FRP dual-laminate construction for decades of zero-leak service.
