Advanced Flue Gas Treatment
Advanced Flue Gas Treatment
SHARE
Emission control is one of the most important factors of Waste to Energy (WtE) plant.We have been working on this issue for a long time and have successfully developed a number of technologies in each element of the plant including incineration, flue, gas treatment, and ash treatment.
Base on MHIEC's (Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd.,) accumulated technologies and know - how developed through long experiences, we can propose the advanced & environmental friendly flue gas treatment system.
Recycle of Usable Metals
| EURO 2000 Regulations | Mitsubishi WtE Plant A (288 t/day x 3 units) |
|
|---|---|---|
| Dioxins (ng-TEQ/Nm³) | 0.1 | 0.00011 |
| Dust (mg/Nm³) | 10 | 3 |
| HCl (mg/Nm³) | 10 | 2 |
| SOx (mg/Nm³) | 50 | 4 |
| NOx (mg/Nm³) | 200 | 110 |
Filtering reactor
Dry system with filtering reactor
- High and stable performance for removal of HCl, SOx and Dust.
- No waste water treatment is required.
Semi-dry system with filtering reactor
- High and stable performance for removal of SOx and Dust, equivalent to Dry system with filtering reactor.
- Higher performance for removal of HCl, because slurry lime doing by Mitsubishi Rotary Atomizer.
- No waste water treatment is required.
Selective catalytic reactor
Dry selective catalytic reactor NOx removal system (SCR)
- Additional facility which can be installed after filtering reactor and achieve higher De-NOx performance.
- Less than 20 ppm of outlet NOx emission can be achieved.
- Low ammonia consumption, because of highly efficient catalytic reaction.
Hybrid Bag Filter
- In addition to the conventional functions of the filtering reactor (i.e. removal of HCl/ SOx/ Dust), Mitsubishi Hybrid Bag Filter can achieve high De-NOx performance.
- Mitsubishi Hybrid Bag Filter provides a total solution for emission control.
- Maintenance is easy because of its simple structure.
