Integrated Multi-Pollutant Synergistic Ultra-Low Emission System with Ceramic Catalysts for Coking Industry
Flue Gas Characteristics:
- Low temperature with significant fluctuations
- High concentrations of NOx, SO₂, and H₂S
- Contains organic components and tar
Traditional Process Challenges:
❌ Low and unstable flue gas temperatures
❌ Complex pollutant composition with high viscosity
❌ Significant ammonia slip, difficult to control
❌ Requires hot standby chimney (>130°C)
New Process Advantages:
✅ Integrated treatment for efficient removal of sulfur, nitrogen oxides, and particulates
✅ Dry conditioning & desulfurization achieves dewhitening and tar absorption
✅ Solid waste recycling minimizes disposal volume
✅ Minimal heat loss maximizes waste heat recovery
✅ Dual regeneration modes: isolated catalyst regeneration & online catalyst regeneration
✅ Low O&M costs with optimized energy efficiency
Key Innovations:
• Operates effectively at 90-180°C without reheating
• 99% SO₂/NOx removal despite tar interference
• 50% lower ammonia consumption vs. SCR systems
• Eliminates visible steam plume ("white smoke")
Typical Performance Metrics:
▸ Outlet SO₂ <30mg/Nm³
▸ NOx <100mg/Nm³
▸ Particulates <10mg/Nm³
▸ Ammonia slip <3ppm
