    AI Overview
    Wet Electrostatic Precipitator -
    Sulphonation plant exhaust gas treatment typically uses electrostatic precipitators (ESPs)—often specialized wet-type (WESP)—to remove
    SO3cap S cap O sub 3
    𝑆𝑂3
    , sulfuric acid mist, and organic aerosol contaminants from sulphonation reactor vents. ESPs achieve high efficiency by electrically charging mists and particulates for collection on tubes or plates, often complemented by scrubbing for
    SO2cap S cap O sub 2
    𝑆𝑂2
     reduction. 
    Key Aspects of ESP Treatment in Sulphonation Plants: 
    • WESP Functionality: Wet ESPs are favored as they handle sticky residues and prevent re-entrainment of particulates, ensuring consistent performance on condensable acid mists.
    • Components and Design: Specialized ESPs often feature stainless steel (SS) tubes instead of wires to avoid breakage and utilize a "hollow-out" plate design to prevent the accumulation of "black acid".
    • Performance Metrics: Modern, high-voltage (e.g.,
      40
      ,
      000
      V
      ) WESPs can effectively treat fine particulates, offering a reliable solution for cleaning hazardous effluent gases before atmospheric release.
    • System Integration: ESPs are commonly placed after the sulfonation reactor, and ahead of or integrated with scrubbing stages (e.g., caustic scrubbers) that neutralize
      SO2cap S cap O sub 2
      𝑆𝑂2
      .
    • Process Improvements: Advanced systems, like those from NJWeixian, offer the ability to circulate ESP exhaust gas back into the process, reducing waste water and caustic soda consumption. 
    Exhaust Gas Composition Challenges: 
    • 𝑺𝑶𝟑

       Mist:       Formed by residual moisture in the air system.
    • Organic Aerosols: Entrained materials from the sulphonation process.

    For high-efficiency removal of submicron particulates, specialized Beltran Technologies wet ESPs are used to capture these aerosols with minimal energy consumption.
