Acid Fume Treatment
Industrial processes that generate acidic fumes and inorganic gases face increasingly strict environmental and health regulations. Compounds such as HCl, HF, H₂SO₄ mist, SO₂, and NOx contribute to air pollution, corrosion, and toxic exposure.
Ecosystems Europe delivers comprehensive acid fume treatment solutions that combine wet scrubbing, aerosol demisting, and activated carbon polishing — engineered to achieve up to 99.9% removal efficiency and full compliance with EU IED and BAT-AEL standards.
Why it matters
Acid fumes are among the most corrosive and hazardous emissions in industry. Without effective treatment, they lead to:
With tightening emission thresholds across Europe and globally, effective acid gas treatment systems are no longer optional — they are essential for safe, sustainable operation.
Our integrated treatment approach
Ecosystems designs modular, high-efficiency treatment systems that combine three core technologies:
1. Wet scrubbing — primary acid gas removal
Our wet scrubbers neutralize and absorb acid gases such as HCl, HF, SO₂, and NO₂ using optimized water or alkaline solutions. Designed for minimal reagent use, they enable chemical recovery and reduced effluent generation.
2. Aerosol demisting — fine mist and sub-micron capture
Acid scrubbing often generates fine acid mists and aerosols (<1 µm). These cannot be captured by traditional separators.
Our systems integrate Elessent® Brink® Fiber Bed Mist Eliminators, providing:
This stage ensures that acid mist, SO₃, H₂SO₄, and condensable vapors are effectively removed, keeping downstream air clean and visible emissions near zero.
3. Activated carbon filtration — final polishing
For trace contaminants, activated carbon beds provide final polishing and odor control.
They adsorb residual chlorinated compounds, VOCs, and sulfur species, guaranteeing compliance with the lowest emission limits.
Regulations and safety
Ecosystems systems are designed in line with:
Typical Emission Benchmarks (Daily Average):
| Compound | Typical Limit (mg/Nm³) | Application |
|---|---|---|
| HCl | 0.5 – 5 | Metal pickling, incineration |
| HF | 0.1 – 3 | Aluminum, fertilizer, glass |
| H₂SO₄ mist | < 10 | Acid production, battery recycling |
| SO₂ | < 200 | Combustion, refining |
| NH₃ | 1 – 10 | Fertilizer and wastewater plants |
All systems prioritize safety, low chemical consumption, and operator-free automation, with corrosion-resistant materials and fail-safe controls.
