Abstract RU 2245355 C1

FIELD: composition for crude oil treatment in oil producing and oil refinery industry.

SUBSTANCE: claimed composition is obtained by mixing of four components. Oxyethylated isononylphenone sodium carboxymethylate of formula C₉H₁₉-C₆H₄-O-(-CH₂-CH₂O)_nCOONa, where n = 12 is used as an active ingredient. Silicone is introduced in composition as self-emulsifying addition, and aqueous or aqueous-salt solution is used as solvent. Composition contains (mass %) oxyethylated isononylphenone sodium carboxymethylate 25-35; self-emulsifying silicone addition 0.01-1.0; calcium chloride 0-25; and as balance: water.

EFFECT: composition with high demulsifying action and reduced foaming formation in crude oil emulsion.
