SO2 Emission Control | BLDJ1W\/100W Single Alkali Desulfurization System<\/span><\/h2>\n

Eradicate Sulfur Dioxide (SO2) compliance risks instantly. Engineered by Ever-power, the BLDJ1W\/100W Single Alkali Flue Gas Desulfurization (FGD) system is the ultimate solution for medium-to-small boilers and space-constrained industrial projects. Utilizing a highly reactive sodium-based absorbent, we guarantee outlet emissions below 35 mg\/Nm3<\/strong> without the scaling and clogging nightmares associated with traditional calcium methods.<\/p>\n

        The Single Alkali Working Principle<\/h3>\n

        The Single Alkali process utilizes a highly soluble sodium-based absorbent (typically Sodium Hydroxide NaOH or Sodium Carbonate Na2<\/sub>CO3<\/sub>) to react with sulfur dioxide in the flue gas. Because sodium salts are highly soluble, the absorption takes place in a “clear liquid” state, completely eliminating the scaling and blockages that plague calcium-based systems inside the tower.<\/p>\n

        Core Chemical Reactions (Using NaOH):<\/strong><\/p>\n

          \n
        1. Hydration:<\/strong> SO2<\/sub> + H2<\/sub>O \u21cc H2<\/sub>SO3<\/sub><\/li>\n
        2. Primary Absorption:<\/strong> H2<\/sub>SO3<\/sub> + 2NaOH = Na2<\/sub>SO3<\/sub> + 2H2<\/sub>O (Forms sodium sulfite)<\/li>\n
        3. Excess Absorption:<\/strong> H2<\/sub>SO3<\/sub> + Na2<\/sub>SO3<\/sub> = 2NaHSO3<\/sub> (Forms sodium bisulfite when SO2<\/sub> is in excess)<\/li>\n<\/ol>\n
