Interfacial rheological studies of extra-heavy crude oils and asphaltenes: role of the dispersion effect of resins in the adsorption of asphaltenes at the interface of water-in-crude oil emulsionsa
The interfacial behaviour of a crude oil and an asphaltene system has been studied by a planar rheological method. System S, was a 30% (v/v) xylene dilution of extra-heavy Cerro Negro crude oil; the aqueous phase was tridistilled water or an NaCl solution (2% (w/v)). System S2 was a 3.21% (w/v) dilu...
