AI Overview
conversion, multi-tube sulfonation/sulfation, neutralization, and, critically for SLES, 1,4-Dioxane stripping to meet safety standards.
Key Components of an SLES Plant
- Sulphonation/Sulphation Reactor: Multi-tube falling film reactors are the industry standard, allowing for precise control of temperatures during the reaction of fatty alcohol ethoxylate (FAlEO) with .
- 1,4-Dioxane Removal Unit: Advanced plants, such as those by Marsina Engineering, include vacuum film evaporators that reduce dioxane to under 3 ppm, making the SLES suitable for cosmetic use.
- Neutralization System: Employs high-shear mixers to neutralize the acidic product with caustic soda immediately, ensuring stability.
- Gas Treatment: Electrostatic precipitators (ESP) and scrubbing systems remove exhaust gas pollutants ().
Key Technology Providers
- WEIXIAN: Offers capacities from pilot scale up to 10 t/h (using 192-tube reactors) with advanced heat recovery.
- Marsina Engineering: Specializes in sustainable, energy-efficient, and low-dioxane SLES plants.
- Desmet Ballestra: A well-known provider of high-capacity sulphonation technologies.
- Chemithon: A key technology supplier for surfactants.

How is sulphonation used in detergents?
Role of Sulfonation in Detergents
described in the following way: 1) Wetting of the substrate and dirt due to reduction of surface tension; 2) Remotion of dirt from substrate; 3) Retaining the dirt in a stable solution or suspension.
