Mechanism of Crude-Oil/Water Interface Destabilization by Silicone Demulsifiers
Measurements of interfacial prop-
erties were performed in order to understand the mode of action of polysiloxane demulsifiers .
Experimental Investigation of Emulsion Stability in Gas/Oil Separation Plants
Polysiloxane DB is an efficient demulsifier on different types of crude oils (Dalmazzone et al.
Use of centrifugal extractor in a plant for refining oils by phenol
The use has also been suggested of adding some demulsifiers and other sur-
face-active materials, especially sodium, zinc, or ammonium salts of alkylbenzene sulfonic
acids , polymetallic salts of naphthenic acids , polysiloxane liquids , etc. in
certain quantities (0.02...
New Silicon Copolymers For Efficient Demulsification
...silicones, which are used as effective demulsifying agents, are generally based on a polysiloxane backbone with polyether... A new silicone-based demulsifier was synthesized that contains polyether in the backbone and silicon-containing substituents.

Lab and Field Study of New Microemulsion-Based Crude Oil Demulsifiers for Well Completions
...a fines stabilized emulsion requires the use of
acids in combination with the demulsifier to be effective. Non-toxic polysiloxane surfactants have
been the subject of recent studies (Dalmazzone et al. 2005).
