Abstract (en)
[origin: EP0732144A1] A method for preparing oil in water HIPR emulsions includes the steps of providing a Newtonian liquid including a mixture of a viscous hydrocarbon, an emulsifying additive and water; subjecting the Newtonian liquid to a first shear force whereby a substantial portion of the Newtonian liquid is radially displaced and mixed so as to form a non-Newtonian liquid; thereafter subjecting remaining non-radially displaced Newtonian liquid to a second shear force to mix the remaining non-radially displaced Newtonian liquid into the non-Newtonian liquid to form the HIPR emulsion, which emulsion is a stable oil in water emulsion having a droplet size of between about 1 to 30 microns and having a droplet size distribution (x) no greater than about 1, the droplet size distribution being defined as follows: <MATH> wherein D90 is a droplet size wherein about 90% by volume of all droplets in said emulsion are equal to or below; D10 is a droplet size wherein about 10% by volume of all droplets in said emulsion are equal to or below; and D50 is a droplet size wherein about 50% by volume of all droplets in said emulsion are equal to or below.
