Clean Air & Corrosion Control for Surface Treatment Lines
Anodizing, electroplating, etching/pickling, phosphating and passivation can release corrosive gases, acid mists and solvent odours. Ravebo designs and builds tailored wet-scrubber systems that protect people and assets, prevent nuisance and keep permits intact.
Why emission control matters in surface treatment
Corrosive media, sensitive neighbourhoods and variable airflows demand predictable, low-maintenance abatement. The right system safeguards people and equipment and keeps production compliant.
-
Compliance & permits
Meet strict limits for acid mists and VOCs; audit-ready records. -
Worker & community safety
Capture toxic/odorous emissions before release. -
Asset protection
Reduce corrosion on ducts, cranes, stacks and nearby equipment. -
Operational continuity
Stable performance with predictable OPEX.
Key challenges in surface treatment
From hexavalent-chromium mists to mixed acid fumes and humid exhaust—lines need robust capture, separation and drainage across changing loads.
Top challenges
-
Acid mists & aerosols
H₂SO₄, HNO₃, HCl, HF and Cr(VI) around tanks and rinse stations. -
Oxidants & NOx
Nitric-based steps can form brown NOx and corrosive fumes. -
High humidity & carry-over
Moist exhaust requires efficient droplet removal and drainage. -
Materials & effluent
Correct plastics/alloys and proper blow-down treatment.
Ravebo solutions for Surface Treatment
We configure wet scrubbers per line—matching absorption chemistry, droplet separation, materials and controls for compliant, low-maintenance performance.
Packed-bed absorption
High-efficiency gas absorption for acid/base gases (HCl, H₂SO₄, HF, HNO₃, NH₃) with the right liquor and residence time.
Mist elimination & drainage
Multi-stage droplet separation with re-entrainment control for humid, corrosive exhaust.
Capture hoods & enclosures
Edge/slot hoods, tank covers and airflow control tailored to line geometry and operations.
Materials & construction
PP, PE, PVC-C, FRP or PVDF/PTFE; stainless/special alloys where required—selected for chemistry, temperature and lifetime.
Control & documentation
Inline pH/ORP/conductivity, flow/level control and permit-ready reporting; integration with site DCS/BMS.
Hexavalent-chromium mist control at plating shop
A metal-finishing facility reported exceedances and corrosion near the stack. Ravebo supplied a compact, multi-stage scrubber with packed-bed absorption and high-efficiency mist elimination, tied into capture hoods and blow-down handling.
- >99% acid-mist reduction (application-dependent)
- Reduced corrosion on nearby equipment
- Permit compliance with audit-ready documentation
