A method of preparing an emulsion comprising a first liquid and a second liquid, said method comprising the step of dispersing the first liquid into the second liquid, wherein the method comprises: - passing the first liquid through an injection nozzle for creating a spray of droplets of the first liquid, characterized in that - the first liquid is injected in a container providing a free path length for the spray from the nozzle that is larger than the penetration depth of the spray in the second liquid, and - the injection of first liquid is done in more than one injection step; and wherein the method further comprises - injecting the first liquid in the form of the thus created droplets of first liquid into the second liquid such that Q, where Q is equal to the square of the speed of the droplets, the speed being the exit speed of the first liquid from the nozzle in air under standard temperature of 20°C and ambient air pressure of 1 atm, is at least 225 m 2 /s 2; wherein W, where W is sg * Q * d divided by St with - sg being the specific gravity of the first liquid in kg/m 3, - d being the mean Sauter droplet diameter in meter of the spray leaving the injection nozzle in air, and - St is the surface tension of the first liquid in Newton/meter; is at least 250 kg*m/N*s 2. - passing the first liquid through an injection nozzle for creating a spray of droplets of the first liquid, characterized in that - the first liquid is injected in a container providing a free path length for the spray from the nozzle that is larger than the penetration depth of the spray in the second liquid, and - the injection of first liquid is done in more than one injection step; - the first liquid is injected in a container providing a free path length for the spray from the nozzle that is larger than the penetration depth of the spray in the second liquid, and - the injection of first liquid is done in more than one injection step; and wherein the method further comprises - injecting the first liquid in the form of the thus created droplets of first liquid into the second liquid such that Q, where Q is equal to the square of the speed of the droplets, the speed being the exit speed of the first liquid from the nozzle in air under standard temperature of 20°C and ambient air pressure of 1 atm, - injecting the first liquid in the form of the thus created droplets of first liquid into the second liquid such that Q, where Q is equal to the square of the speed of the droplets, the speed being the exit speed of the first liquid from the nozzle in air under standard temperature of 20°C and ambient air pressure of 1 atm, is at least 225 m 2 /s 2; wherein W, where W is sg * Q * d divided by St with - sg being the specific gravity of the first liquid in kg/m 3, - d being the mean Sauter droplet diameter in meter of the spray leaving the injection nozzle in air, and - St is the surface tension of the first liquid in Newton/meter; - sg being the specific gravity of the first liquid in kg/m 3, - d being the mean Sauter droplet diameter in meter of the spray leaving the injection nozzle in air, and - St is the surface tension of the first liquid in Newton/meter; is at least 250 kg*m/N*s 2.
