Formation of emulsions in paraffinic and highly resinous oils
Results of the study of emulsion formation in paraffinic and highly resinous oils are presented. The influence of the composition of resin-asphaltene components and the water content in oils on the chilling temperature, rheological properties and the activation energy of the viscous flow of water-oil emulsions is revealed. It is established that in water-oil emulsions large stable water globules are formed, the solidification temperature, viscosity and the activation energy of the viscous flow are increased. Emulsions of highly resinous oils are characterised by the formation of structures with small water globules, high viscosity and a low activation energy of the viscous flow. Power dependence of the size of water globules in water-oil emulsions on the ratio of the contents of resin-asphaltene components and paraffinic hydrocarbons is established.
