Wet Flue Gas Desulfurization Limestone/Gypsum

Technical Features:

Limestone-Gypsum Flue Gas Desulfurization Technology is mature, easy to operate, and well-managed.

2. High desulfurization efficiency of over 95%, highly adaptable to various coal types, suitable for high, medium, and low sulfur coal, and currently the most effective desulfurization method.

3. Absorbent: Limestone or lime, a wide source for desulfurizing agent at a low cost.

4. Method with a desulfurization agent calcium-to-sulfur ratio of Ca/S ≤ 1.03, featuring high utilization rate and low consumption rate of the desulfurizing agent.

5. Desulfurization products are gypsum (calcium sulfate dihydrate). Gypsum quality: Approximately 90% purity, suitable for use as building materials, and easy to handle and comprehensively utilize.

6. Water consumption is related to parameters such as flue gas treatment volume and flue gas temperature, with minimal wastewater discharge and the ability for reuse after treatment.

7. Large-scale technology matured, with strong applicability for the units, catering to various capacities - from large to small.

8. The system operates stably with excellent load change characteristics.
