Effect of natural surface-active substances on the rheological properties of emulsions

The effect of natural surface-active substances on the formation of emulsions in oils with different content of resin-asphaltene components (RAC) and paraffin hydrocarbons (PHC) (RAC/PHC from 0.7 to 95) is studied. The influence of oil composition and content of aqueous phase on microstructure, rheological properties, and activation energy of viscous flow of water-oil emulsions is shown. For oils with the ratio RAC/PHC < 1, the increase in water cut results in an increase in viscosity, activation energy of viscous flow, and pour point
