    AI Overview
    Sulphonation AOS (Alpha Olefin Sulfonate) production requires intensive, precise chilling water cooling to manage highly exothermic reactions. The process uses specialized units to supply

     water to the reactor shell and neutralization/aging sections, preventing over-reaction, ensuring product stability, and maintaining 100% sealing efficiency with high-pressure, corrosion-resistant, and high-efficiency sealing. 
    Sulphonation AOS Chilling Process Key Elements 
    • Chilling Water System Setup: The system includes a chiller group (like LiBr units), a water tank, and circulating pumps.
    • Dual Circulation Loop: One pump cycle cools the water through the chilling group, while the second pump circulates the chilled water directly to the sulfonator shell, reactor jacket, and neutralization system.
    • Temperature Control (15°C): Crucial for managing the highly exothermic reaction and stabilizing the product.
    • High-Pressure Sealing: Chilled water sealing (often using Viton O-rings) is critical at the reactor inlet and shell for efficient heat dissipation and leakage prevention, specifically in AOS production.
    • Process Sequence: The system provides cooling during sulphonation, aging, and product neutralization to maintain consistent quality and prevent fouling. 
    The chilling unit generally supports the overall sulfonation process, which includes air drying, sulfur burning,
