Apparatus for the preparation of emulsions of oil in water comprises: (a) an oil feed line, (b) a source of concentrated surfactant solution, (c) a source of water, (d) a first low shear mixer for mixing concentrated surfactant and water to form a dilute surfactant solution, (e) means for uniting the flows of dilute surfactant solution and oil in a controlled manner, (f) a second low shear mixer for mixing the united flow streams of oil and dilute surfactant solution to form an emulsion of oil in water, (g) a third low shear mixer for mixing the emulsion...
A method for the preparation of an emulsion of an oil in water which method comprises the steps of: (i) mixing concentrated surfactant with water in a first low shear mixer to form a dilute surfactant solution, (ii) uniting a flow of oil having a viscosity in the range of 25 to 250,000 mPa\s at the mixing temperature with the flow of dilute surfactant solution in a controlled manner such that a core of surfactant solution flows within an annulus of the oil, the combined flow containing 60 to 98% by volume of oil, (iii) passing the united flow of oil and ...
