AI Overview
A Sodium Lauryl Ether Sulfate (SLES) pH adjusting unit stabilizes the pH, homogenizes, and fine-tunes SLES/SLS product specifications after sulfonation. These units typically feature agitated, stainless steel tanks, often operating in intermittent batches, that neutralize acidity and check parameters like free oil, dioxane, and color before storage.
This video explains the functionality of the SLES/SLS pH adjustment unit:
Key Features and Components
- Neutralization System: Uses caustic soda (Sodium Hydroxide) to raise the pH or acids to lower it, typically targeting a neutral pH for final products.
- Agitation/Mixing: Employs high-efficiency agitators designed for rapid homogenization, often aiming for 1.5–2 tank turnovers per minute.
- Process Control: Involves sampling at regular intervals to verify product quality, including neutralization value and color.
- Optional Enhancements: Includes post-deaeration systems to remove excess air bubbles for better product transparency.
- Material: Usually constructed from high-quality, corrosion-resistant stainless steel.
Common Applications
- SLES/SLS Production Lines: Integrated into sulphonation/sulphation plants to ensure the final product meets commercial specifications.
- Wastewater Treatment: Used to adjust the pH of industrial waste streams to a safe, dischargeable range.
These units can be customized to specific production capacities, ensuring consistent quality for high-volume, continuous sulfonation processes.
