Qianzishan Waste-to-Energy Project – Emergency Odor Control Using Pelletized Activated Carbon
2025-07-30
| Location: | Wuhan, China |
| Industry: | Municipal Solid Waste Incineration |
| Application: | Odor and VOC removal in emergency deodorization system |
| Product Used: | Coal-based pelletized activated carbon (iodine value ~850 mg/g) |
| Project Start: | March 2024 |
Project Overview
In response to a sudden increase in odor emissions during the expansion phase of the Qianzishan WtE plant, a rapid-response deodorization system was deployed. The system integrates plant-derived liquid spray scrubbing with a fixed-bed activated carbon adsorption module. The target pollutants include hydrogen sulfide (H₂S), ammonia (NH₃), and a broad spectrum of sulfur- and nitrogen-containing VOCs.
Technical Parameters
Airflow rate: 50,000 m³/h
Pollutant concentration:
- H₂S: 10-50 mg/m³
- NH₃/VOCs: <100 mg/m³
Carbon type: Pelletized coal-based activated carbon (φ4 mm, iodine ≥850 mg/g)
Process: Fixed-bed adsorption with replaceable media trays
Performance Results
- Average removal efficiency: 94.1%
- Stable operation under fluctuating gas load
- No breakthrough observed after 30 days of continuous use
Standards & Monitoring
- Real-time odor monitoring (TVOC, H₂S sensors)
- Compliance with local fugitive emission limits for waste incineration plants
