Features Of Solvay Clearbreak RE 4618 Surfactant

  1. High-efficiency demulsifier specifically engineered for rapid separation of water-in-oil emulsions.

  2. Thermally stable formulation effective across a broad temperature range (20–90 °C).

  3. Low foaming profile, minimizing operational interference in high-shear processing environments.

  4. Compatible with common hydrocarbon solvents and refinery streams, including naphtha, diesel, and crude fractions.

  5. Non-ionic, ethoxylated alkylphenol-free chemistry supporting evolving regulatory and sustainability requirements.

Typical Applications Of Solvay Clearbreak RE 4618 Surfactant

  1. Crude oil dehydration in upstream production and midstream terminals.

  2. Refinery feed pretreatment to protect desalters and downstream units from emulsion carryover.

  3. Wastewater treatment in petrochemical facilities for oily water separation.

  4. Demulsification in fuel blending and storage systems to ensure product specification compliance.

  5. Process aid in lubricant and base oil manufacturing for water removal.
