Studies on Demulsification Mechanism of Demulsifier for the Three compound Combination Flooding Effluent Emulsions

Abstract

Abstract: The effects of demulsifiers on interfacial tensions and membrane strength were studied for the model and effluence systems from the three compound combination flooding field. The interfacial tensions owned by the two compound combination system decreased but those owned by the three compound combination system increased with increasing the demulsifier concentrations. Membrane strength decreased with the increase of demulsifier. The demulsification mechanism of demulsifier is suggested that demulsifier partially replaces the stabilizers and greatly decreases the intensity of interfacial film.

Key words: Demulsifier, Low interface tension, Interfacial activity, Adsorption, Membrane strength
