Limestone gypsum flue gas desulfurization technology and equipment

The limestone-gypsum desulfurization process is currently the most widely used desulfurization technology. Approximately 90% of flue gas desulfurization systems used in thermal power plants in Japan, Germany, and the United States utilize this process. Through desulfurization efficiency enhancement technology, it can achieve desulfurization efficiencies exceeding 95%.

[Units]: Medium and large-scale units with a capacity of 200 MV and above

[Desulfurization Efficiency]: Over 95%

[Applications]: Exhaust gas treatment for boilers burning coal, heavy oil, Orimulsion, petroleum coke, and other fuels

Product Advantages

  1. High desulfurization efficiency: Desulfurization efficiency enhancement technology achieves over 95% efficiency.
  2. Wide range of absorbent applications: A variety of absorbents can be used in FGD units, including limestone, lime, magnesia, and waste soda solutions.
  3. Zhuanli process technology: Effectively reduces the liquid/gas ratio, achieves high absorbent utilization, promotes uniform airflow distribution within the tower, saves material and energy consumption, and facilitates internal component maintenance.
  4. Cross-spray pipe layout technology: Reduces absorption tower height.
  5. Strong adaptability to unit load fluctuations: Stable operation within a load range of 15% to 100% is possible.
  6. High by-product purity: Commercial-grade gypsum with a purity exceeding 95% can be produced.
  7. High dust removal efficiency for coal-fired boiler flue gas: Reaching 80% to 90%.

Working Principle

Desulfurization process
CaCO3+SO2+1/2H2O→CaSO3·1/2H2O+CO2
Ca(OH)2+SO2→CaSO3·1/2H2O+1/2H2O
CaSO3·1/2H2O+SO2+1/2H2O→Ca(HSO3)2

Oxidation process
2CaSO3·1/2H2O+O2+3H2O→2CaSO4·2H2O
Ca(HSO3)2+O2+2H2O→CaSO4·2H2O+H2SO4
