Sodium alkali desulfurization technology

Sodium alkali desulfurization technology

The sodium-alkali desulfurization process uses sodium-based alkali (sodium hydroxide, sodium carbonate, etc.) solution as an absorbent to remove sulfur dioxide in flue gas, and the desulfurizer absorbs sulfur dioxide to generate sodium sulfite. Sodium sulfite plays a major role in absorption during the circulation process. It absorbs sulfur dioxide to form sodium bisulfite, and then undergoes forced oxidation to form sodium sulfate.

Features

    • The efficiency of removing inkstone is high, and the highest can reach more than 99%;
    • system is concise, less investment, small footprint;
    • reliable operation, high solubility of sodium and alkali, no scaling or blockage in the absorption system; Sodium-alkali has high absorption activity, low liquid-to-gas ratio, and low power consumption;
    • absorbent is expensive and has high operating costs. It is only suitable for companies that produce their own alkali or waste alkali.
