Features Of Solvay Clearbreak 291 Surfactant

  1. Highly effective nonionic surfactant for rapid and complete emulsion breaking in oil/water systems.

  2. Thermally stable across a broad operating temperature range, maintaining performance up to 80 °C.

  3. Low foaming profile, minimizing interference in separation processes and downstream equipment operation.

  4. Compatible with common hydrocarbon streams and tolerant to moderate salinity and hardness levels.

  5. Eco-profile optimized for reduced aquatic toxicity relative to legacy alkylphenol ethoxylates.

Typical Applications Of Solvay Clearbreak 291 Surfactant

  1. Crude oil dehydration and desalting units in upstream and midstream refining operations.

  2. Produced water treatment for offshore and onshore oil & gas facilities.

  3. Emulsion breaking in refinery wastewater pretreatment systems.

  4. Demulsification of fuel oil and lubricant emulsions during storage and handling.

  5. Process aid in chemical manufacturing where stable oil-in-water emulsions require controlled destabilization.
