Oxyalkylated phenol/formaldehyde resin for desalter applications in the refinery Industry |
摘要 |
Certain base catalyzed oxyalkylated-cardanol-alkylphenol-aldehyde resins may be utilized in refinery demulsification operations. These materials find particular utility in breaking water-in-oil emulsions resulting from the water wash of crude oils. The materials may also be employed to break other water-in-oil refinery emulsions.
