Desulfurization and Denitrification Additive

At present, flue gas desulfurization and denitrification from kilns generally adopt limestone-gypsum desulfurization and NH₃ selective catalytic reduction (SCR) denitrification. However, the separate treatment of SO₂ and NO presents issues such as large land occupation, complex equipment, high investment and operating costs, low utilization value of by-products, and secondary pollution, making it difficult to meet increasingly stringent environmental protection requirements. Therefore, the development of cost-effective integrated desulfurization and denitrification technologies has become a key focus of research and development among relevant enterprises worldwide.
The integrated desulfurization and denitrification chemical additives developed by our company combine desulfurization and denitrification into a single process flow. This not only simplifies the process and equipment with a compact structure, but also reduces by-products, construction costs and operating expenses.

I. Product Performance Features

  1. Simple process and convenient operation: The desulfurization and denitrification agent is sprayed into an appropriate position in the kiln furnace via a powder conveying system to achieve desulfurization and denitrification.
  2. Low one-time project investment: The one-time investment in equipment required for this technology is only 15%~30% of that for traditional desulfurization and denitrification methods such as limestone, dual-alkali and liquid ammonia processes.
  3. Low operating cost: The combined operating cost of integrated desulfurization and denitrification is low.
  4. Excellent treatment effect: The emission concentrations of SO₂ and NO in boiler flue gas can be simultaneously reduced to meet or even fall below the latest national flue gas emission standards, with controllable adjustment according to enterprise requirements.
  5. No by-products and no secondary pollution: It reduces labor intensity and eliminates expenses such as waste removal, secondary pollution treatment and wastewater treatment.
  6. Energy-saving effect: After application, ash deposition and coking on boiler tube walls are removed, accelerating heat conduction and reducing heat loss. This achieves energy savings of 1%~3% for mild ash deposition and coking, and up to 4%~7% for severe cases.

II. Packaging and Storage

  1. Powder products are packaged in film-coated plastic woven bags or supplied in bulk.
  2. Liquid products are packaged in iron drums (200 kg per drum) or stored and transported directly by tank trucks. Store in a cool place. When sealed in original packaging, the shelf life is 24 months at 0℃~50℃. Products beyond the shelf life shall be re-sampled and tested before application.
