a transportable platform,

a first fluid circuit disposed on said platform in flow communication with said source of hydrocarbon fuel;

a second fluid circuit disposed on said platform in flow communication with said source of fuel emulsion additives;

a first blending station disposed on said platform in flow communication with said first and second fluid circuits and adapted to mix said hydrocarbon fuel and said fuel emulsion additives;

a second blending station disposed on said platform in flow communication with said first blending station and said source of water, said second blending station adapted to mix said hydrocarbon fuel and additive mixture from said first blending station together with said water; and

an emulsification station disposed on said platform in flow communication with said second blending station, said emulsification station adapted to emulsify said hydrocarbon fuel, fuel emulsion additives and water mixture to yield said fuel emulsion;

wherein said fuel emulsion blending system is readily transportable from a first location to an alternate location.

2. The fuel emulsion blending system of claim 1 wherein said emulsification station comprises a high shear mixer adapted to emulsify said hydrocarbon fuel, fuel emulsion additive and water mixture.

3. The fuel emulsion blending system of claim 2 wherein said emulsification station further comprises a recycling circuit adapted for recycling said fuel emulsion exiting said high shear mixer back through said high shear mixer.

4. The fuel emulsion blending system of claim 1 further comprising one or more holding tanks disposed on said platform and wherein said source of hydrocarbon fuel is disposed in one of said tanks.

5. The fuel emulsion blending system of claim 1 further comprising one or more holding tanks disposed on said platform and wherein said source of fuel emulsion additives is disposed in one of said tanks.

6. The fuel emulsion blending system of claim 5 further comprising a third fluid circuit disposed on said platform in flow communication with said source of water.

7. The fuel emulsion blending system of claim 6 wherein said third fluid circuit further includes a water purification unit for purifying said water to a prescribed purity level.

8. The fuel emulsion blending system of claim 7 wherein said third fluid circuit further includes a water conductivity sensor disposed in operative association with said third fluid circuit and adapted for measuring the purity of said water flowing through said third fluid circuit.

9. The fuel emulsion blending system of claim 6 wherein one or more of said fluid circuits includes a flow measuring device adapted for measuring the flow through said fluid circuit.

10. The fuel emulsion blending system of claim 6 wherein one or more of said fluid circuits include a flow control device adapted for adjusting the flow through said fluid circuit in response to a control signal received from said blending system controller.

11. The fuel emulsion blending system of claim 1 further comprising one or more holding tanks disposed on said platform and wherein said source of water is disposed in one of said tanks.

12. The fuel emulsion blending system of claim 1 further comprising a blending system controller operatively associated with one or more fluid circuits and adapted for controlling the mixing ratio of said hydrocarbon fuel, said fuel emulsion additives, and said water.
