Abstract
Water-in-crude oil emulsions based on different crude oils from the Norwegian Continental Shelf have been prepared, characterized and destabilized. The destabilization was undertaken with ionic and non-ionic surfactants (Aerosol OT and Triton N-42), fluorinated surfactants and different polymers like polyethylene glycols and polyacrylates of varying molecular masses. The surfactants investigated seem to destabilize according to an interfacial replacement of the indigenous membrane. This is also revealed by interfacial tension measurements. The flocculation ability of the polymers was characterized by means of UV absorbance measurements on Al 2O 3 suspensions in decane. There is not a single correlation between flocculation efficiency and destabilization of the emulsion systems. Model water-in-oil emulsions stabilized by either interfacially active crude oil fractions or by tetraoxyethylene nonylphenol ether were investigated in parallel.
