        The Limestone-Gypsum Reaction Mechanism<\/h3>\n

        The Ever-power WFGD process relies on a continuous, violently agitated, gas-liquid-solid multiphase reaction. Raw flue gas enters the absorber from the bottom and flows upward, making counter-current contact with the limestone slurry sprayed downward.<\/p>\n

        1. Absorption & Neutralization:<\/strong>
        \nSO2<\/sub> + H2<\/sub>O \u2192 HSO3<\/sub>–<\/sup> + H+<\/sup>
        \nSO3<\/sub> + H2<\/sub>O \u2192 H2<\/sub>SO4<\/sub>
        \nCaCO3<\/sub> + H2<\/sub>O \u2192 Ca2+<\/sup> + OH–<\/sup> + CO2<\/sub>
        \nThe acidic components are rapidly absorbed by the water and neutralized by the dissolved calcium ions, forming Calcium Sulfite (CaSO3<\/sub>).<\/p>\n

        2. Forced Oxidation:<\/strong>
        \nHSO3<\/sub>–<\/sup> + O2<\/sub> \u2192 2SO4<\/sub>2-<\/sup> + 2H+<\/sup>
        \nOxygen injected into the lower slurry tank by Roots blowers oxidizes the unstable sulfite into stable sulfate.<\/p>\n

        3. Gypsum Crystallization:<\/strong>
        \nCa2+<\/sup> + SO4<\/sub>2-<\/sup> + 2H2<\/sub>O \u2192 CaSO4<\/sub>\u00b72H2<\/sub>O
        \nThe sulfate combines with calcium and water to precipitate as Calcium Sulfate Dihydrate (Gypsum), which is pumped out via hydrocyclones and vacuum filters for commercial sale.<\/p>\n<\/div>\n
