AI Overview
The SLES (Sodium Lauryl Ether Sulfate) neutralization reactor in a sulfation plant is a high-shear, high-efficiency system designed to instantly neutralize fatty alcohol ether sulfate acid with caustic soda (
), hydrogen peroxide (
), and water. It produces high-quality, low-dioxane SLES, typically featuring a 10x recirculation loop, temperature control below
rise, and superior color/pH stability.
Key Aspects of SLES Neutralization Reactors
- High-Shear/High-Speed Mixing: Ensures uniform neutralization of the acidic product (sulfuric acid half-ester) to prevent localized overheating and byproduct formation, such as 1,4-dioxane.
- Temperature Control: Advanced reactors maintain tight temperature control to prevent product degradation, with special designs restricting the temperature increase to within during neutralization.
- Recirculation Loop: Utilizes a recirculation pump to mix the incoming acid with already neutralized product (10x recirculation) to manage reaction kinetics and heat.
- Dioxane Removal: Often integrated with a vacuum stripping tower (such as the WEIXIAN Unit 79) to remove 1,4-dioxane from the SLES, crucial for meeting modern safety standards.
- Components: Typically includes the neutralization vessel, a high-speed emulsifying pump or circulation pump, pH control system, and feed pumps for and.
- WEIXIAN and Ballestra are prominent suppliers providing specialized SLES neutralization systems, often focusing on ultra-low dioxane technology.
