Clean Air & Surface-Treatment Emission Control for Aeronautics

Q: What emissions are typical in aeronautics?

Acid/alkali fumes and mists (H2SO4, HNO3, HCl, HF, Cr(VI)), solvent VOCs from coating/cleaning, and aerosols/steam from processes such as curing or stripping.

Aircraft manufacturing and MRO involve surface treatment, coating and composite processes that can release acid/alkali fumes, solvent vapours and aerosols. Ravebo designs and builds tailored wet scrubber systems that keep air clean, protect workers and assets, and ensure regulatory compliance.

Why emission control matters in aeronautics

The sector handles corrosive media, hazardous vapours and large, variable airflows. Robust abatement protects people and equipment, prevents neighbourhood nuisance and keeps permits intact.

Regulatory compliance
Meet strict limits for acid mists and VOCs; support REACH/COSHH documentation.
Worker & community safety
Capture toxic and odorous emissions before release.
Asset protection
Reduce corrosion on ducts, stacks and hangar equipment.
Operational continuity
Stable, controllable abatement with predictable OPEX.

Key challenges in aeronautics

From hexavalent chromium mists to solvent-rich exhaust, aerospace facilities need reliable, predictable abatement across variable operating modes.

Top challenges

Acid mists from surface treatment
H₂SO₄, HNO₃, HCl, HF and Cr(VI) aerosols from anodizing/etch lines.
Solvent VOCs from coatings/cleaning
MEK, toluene/xylene, alcohols; odour and compliance issues.
Large & intermittent airflows
Hangar operations and batch processes with peaks and idle modes.
Materials & effluent management
Correct plastics/alloys and proper blow-down treatment.

Aerospace surface treatment and paint operations

Ravebo solutions for aeronautics

We configure wet scrubbers per process — matching absorption chemistry, droplet separation, materials and controls for compliant, low-maintenance performance.

Packed-bed absorption

High-efficiency gas absorption for acid/alkali fumes (HCl, HF, HNO₃, H₂SO₄, NH₃) with the right liquor and residence time.

Mist elimination & polishing

Multi-stage droplet separators and optional polishing (e.g. carbon) to minimise residual VOCs and odour.

Materials & construction

PP, PE, PVC-C, FRP or PVDF/PTFE; stainless or special alloys where required — selected for corrosion resistance and lifetime.

Control & integration

Capture hoods/ducts, airflow control, inline pH/ORP/conductivity monitoring, redundancy and permit-ready reporting.

Case Study

Acid-mist abatement on anodizing line

An aircraft-components factory faced exceedances from surface-treatment tanks. Ravebo supplied a compact, multi-stage scrubber system with packed-bed absorption and high-efficiency mist elimination, integrated with capture hoods and effluent handling.

Aeronautics FAQ

What emissions are typical in aeronautics?

Acid/alkali fumes and mists (H₂SO₄, HNO₃, HCl, HF, Cr(VI)), solvent VOCs from coating/cleaning, and aerosols/steam from processes such as curing or stripping.

Which materials of construction do you use?

PP, PE, PVC-C, FRP or PVDF/PTFE for corrosive media; stainless or special alloys where needed. Selection is based on chemistry, temperature and lifetime requirements.

Can systems handle large, intermittent airflows?

Yes. We design capture hoods and controls for variable flow, with appropriate liquid management and instrumentation to maintain performance during peaks and idle modes.
