Conventional flue gas deacidification process

Conventional flue gas deacidification process has disadvantages

1. Long process parameters are difficult

2. Hazardous chemicals

3. There is a large demand for personnel

4. Occupational exposure risk

5. Low acid removal efficiency of slaked lime

6. The residue contains crystal water, and the production is large

7. Zero discharge of sewage is difficult

8.SCR heating investment and energy consumption is high

9. More serious corrosion/blockage, FPR material overtemperature fire risk

10. The system resistance is high, and the fan power consumption increases

11. The overall investment is large and the comprehensive cost is high

12. Policy risks: Shanghai, Zhejiang, Shanxi, Liaoning, Shaanxi and other local standards for coal-fired power Plant air pollutant emission standards have clearly required: there must be smoke temperature control and other effective measures to eliminate gypsum rain, colored smoke rain, etc

Aier Environmental was awarded the license of SOLVAY in the coal chemical industry in Greater China

SOLVAY deacidification process

Advantages

1. The dry process is simple

2. Less reliability of operating equipment

3. Reduce control points to a fraction to a tenth

4. High one-way efficiency, no cycle

5. Energy consumption is reduced, investment and operating costs are reduced, and post staffing is reduced

6. The process does not consume water or waste water

7. Meet the requirements of “whitening”, and the corrosion of the equipment is weak

8. Avoid corrosion and eliminate the risk of over-temperature fire of FPR material
