Acid and alkali waste gas treatment engineering
Engineered Systems for Corrosive Chemical Fume Neutralization
Our Acid & Alkali Exhaust Treatment Projects deliver high-efficiency, fully automatic neutralization systems designed specifically for industries generating heavy corrosive chemical vapors. Utilizing advanced corrosion-resistant thermoplastics (PP, PVC) and composite materials (FRP), we design, build, and install systems that safely extract, wash, and discharge chemical process exhaust.
System Advantages & Innovations
- Complete Corrosion Resistance: All system components—including hoods, ductwork, scrubbers, and fans—are built from non-metallic, acid-proof materials.
- 99%+ Neutralization Efficiency: Counter-current spray tower technology combined with automated chemical dosing systems guarantees clean stack output.
- Closed-Loop Automatic Dosing: Integrated pH and ORP sensors continuously adjust neutralization chemical injection (NaOH / H2SO4), minimizing chemical waste.
- Zero Gas Leakage Architecture: Engineered under negative pressure differential design to prevent fugitive toxic gas emissions in working zones.
Turnkey Scope of Supply
- Source Capture Hoods: Custom-designed lip hoods, slot hoods, and overhead canopy hoods.
- Ducting & Dampers: Main header ducting, branch lines, and automated balancing dampers.
- Primary Treatment Units: Single or multi-stage FRP/PP Wet Scrubber Towers.
- Chemical Dosing Skids: Dosing pumps, reagent tanks, pH/ORP monitoring instruments, and auto-refill valves.
- Exhaust Blowers & Stacks: High-pressure FRP Centrifugal Fans and outdoor discharge stacks.
