How we turn heavy machinery & shipbuilding exhaust data into a treatment train
The recommended configuration is built around the actual production process, not a generic industry label. This is especially important when one site has multiple exhaust headers, recipes or operating modes.
Common treatment challenges
- Very large airflow (often 100,000+ m³/h class)
- Intermittent booth operation
- Energy cost pressure
Data we request
- Exhaust source, airflow and operating schedule
- VOC/pollutant analysis, concentration range and LEL information
- Temperature, humidity, dust, mist and corrosive components
- Existing collection or pretreatment equipment
- Emission target, layout, utilities and shutdown constraints
Engineering decisions
- Whether streams should be segregated, balanced or treated together
- Which pretreatment protects downstream equipment
- Whether concentration, direct oxidation, recovery or polishing is appropriate
- Materials, safety interlocks, monitoring and maintenance access
- Where recovered heat or utilities can be integrated
Recommended path for heavy machinery & shipbuilding exhaust
This is a decision framework based on the supplied product and project material. The final train changes with measured chemistry, operating patterns and site constraints.
Common emission sources
- Large spray booths and blast/paint rooms
- Shipyard/heavy-equipment coating
- Drying and curing ovens
- Surface-preparation particulate sources
Booth capture → mist filtration → zeolite concentration + RTO or direct RTO
Very large, intermittent coating airflow needs careful collection and diversity analysis. Concentration can reduce downstream oxidizer size for dilute airflow; direct RTO is assessed where load supports it.
- 01Map distributed booth/oven sources
- 02Set capture and pressure-balance strategy
- 03Remove overspray and particulate
- 04Evaluate concentration versus direct RTO
- 05Provide expansion, access and shutdown planning
Rotary RTO configuration
Consider where a compact continuous regenerative layout aligns with the site footprint, maintenance plan and gas-distribution needs.
Process-specific questions
Why are large coating shops difficult to treat?
Airflow can be very high while VOC concentration changes by booth and shift. Duct balance, mist protection, energy use and maintenance access all materially affect the final system.
Can blasting dust share the VOC system?
Usually it needs separate or carefully conditioned treatment. Dry particulate should not be allowed to foul adsorption media or regenerative/catalytic equipment.
