Advanced Sulphonation Technology For LABSA Production
Qino's LABSA production plant utilizes state-of-the-art sulphonation technology to convert Linear Alkyl Benzene (LAB) into high-purity Linear Alkyl Benzene Sulfonic Acid (LABSA). Our proprietary process ensures optimal reaction efficiency, superior product quality, and consistent output meeting international standards.
Core Process Flow
Sulphur Handling & SO₃ Generation
• Molten sulphur system with precise temperature control. • Air drying system for optimal SO₂ generation. • Catalytic conversion tower (V₂O₅ catalyst) for SO₂→SO₃ conversion. • SO₃ cooling system for gas stabilization.
Sulphonation Reaction
• Multi-tube falling film sulphonation reactor. • Controlled reaction temperature: 45-55°C. • Optimal SO₃/LAB molar ratio: 1.02:1. • Reaction time: 10-15 seconds for maximum conversion.
Aging & Hydrolysis
• Aging tank for product maturation (1.5-2.5 hours). • Controlled hydrolysis with 1.5-2.5% water addition. • Acid anhydride conversion to stable sulfonic acid.
Neutralization (Optional)
• Continuous flashing evaporation and neutralization system. • Production of LABSA or direct conversion to LAS (Linear Alkyl Benzene Sulfonate).
Exhaust Treatment
• Multi-stage absorption system for SO₂/SO₃ recovery. • Environmental compliance with minimal emissions. • Waste heat recovery for energy efficiency.
