Abstract
A process provides a stable emulsion, in particularly a stable, concentrated bitumen emulsion, by emulsifying a first hydrophobic or hydrophilic phase having a viscosity between 1 and 5000 Pa.s with a second phase immiscible in the first phase, in the presence of at least one surfactant, by mixing together the first phase, second phase, and surfactant under a laminar shear regime.
