    Sulfur 101: Claus Sulfur Recovery & Claus Tail Gas Treatment
    Sulphonation plant exhaust gas treatment removes harmful
    SO2SO sub 2
    SO2
    ,
    SO3SO sub 3
    SO3
    , and sulfuric acid mist produced during detergent manufacturing (
    𝐿
    ABSA
    /
    𝐿
    ES
    ), typically using wet scrubbing or electrostatic precipitation. Common technologies include caustic soda scrubbers, oxidative scrubbers (using
    H2O2cap H sub 2 cap O sub 2
    𝐻2𝑂2
    ), and high-voltage Electrostatic Precipitators (ESPs) to neutralize emissions and comply with environmental regulations. 
    Key Treatment Methods 
    • Caustic Soda Scrubber (
      SO2SO sub 2
      𝐒𝐎𝟐
       Scrubber):       Exhaust gas is washed with a caustic soda solution to neutralize
      SO2SO sub 2
      SO2
       and
      SO3SO sub 3
      SO3
      , ensuring compliance with environmental standards.
    • Oxidative Scrubbing (
      H2O2cap H sub 2 cap O sub 2
      𝑯𝟐𝑶𝟐
      ):       Uses hydrogen peroxide (
      H2O2cap H sub 2 cap O sub 2
      𝐻2𝑂2
      ) to convert
      SO2SO sub 2
      SO2
       into
      30
      %
       sulfuric acid, which can be reused, achieving "zero sulphite" effluents.
    • Electrostatic Precipitators (ESP): Used for removing
      SO3SO sub 3
      SO3
       and organic acid mists. Modern units, such as those from Weixian, often use 40,000 V electrostatic precipitators to handle these mists efficiently, featuring specialized cathode tubes to avoid "black acid" buildup.
    • Ammonia Injection System: Gaseous ammonia is injected to react with
      SO3SO sub 3
      SO3
       to produce ammonium sulfate, which is subsequently collected by a dry ESP.       
    Exhaust Gas Composition 
    The treatment system addresses several contaminants: 
    • SO2SO sub 2
      𝐒𝐎𝟐
       (Sulphur Dioxide):       Results from incomplete conversion of
      SO2SO sub 2
      SO2
       to
      SO3SO sub 3
      SO3
       in the reactor.
    • SO3SO sub 3
      𝐒𝐎𝟑
      /
      𝑯𝟐
      𝐒𝐎𝟒
       Mist:       Formed from residual moisture in the air system.
    • Organic Acid Mist: Entrained from the sulphonation reactor. 
    Efficiency and Benefits 
    • Pollutant Removal: Modern oxidative scrubbers can achieve significant reductions in
      SOxSO sub x
      SO𝑥
       and
      NOxNO sub x
      NO𝑥
      .
    • Resource Recovery: The process can convert pollutants into valuable 30% sulfuric acid rather than just neutralizing them.
    • Automatic Control: Systems often include automatic controls (e.g., Siemens, ABB) with pH monitoring (e.g., Mettler Toledo) to ensure consistent operation.
