Combined process integrates multiple flue gas treatment technologies (e.g., DSI + wet scrubber, or FSI + other dry systems) to broaden pollutant coverage and maximize cost efficiency. A cost-effective upstream sorbent addresses the bulk pollutant load, while a high‑efficiency downstream system ensures compliance with stringent emission limits. Both DSI or FSI can be added to any wet or dry system to enhance overall performance.
Key benefits
- Enhanced removal of pollutants not captured by the primary system
- Improved overall acid -gas and micro‑pollutant performance
- Optimized sorbent cost across the full treatment chain
- Flexible add‑on design for retrofits or upgrades
Best-fit applications
Plants needing to:
- Meet new/stricter emission limits
- Add missing pollutant removal capabilities
- Upgrade performance without replacing existing FGT systems
