Patent ID: 7559960

Claim:
A method of manufacturing an emulsion of water and fuel using a series of batch processing steps comprising: (a) charging a fuel and an additive into a mixing tank; (b) agitating the fuel and the additive charged into the mixing tank; (c) charging water into the mixing tank and forming a mixture solution of the fuel, additive and water, while agitating the mixture solution; (d) reducing cluster sizes of the fuel and water in the mixture solution by pumping the mixture solution through a processing means and returning the mixture solution into the mixing tank; (e) separating the mixture solution in the mixing tank and forming a water rich portion of the mixture solution at a bottom portion of the mixing tank; and (f) emulsifying the mixture solution from the bottom portion of the mixing tank at first through the processing means and returning the mixture solution to the mixing tank, thereby forming the emulsion of water and fuel, wherein the processing means includes at least one plate having holes therein, and in steps (d) and (f) the mixture solution passes through the holes in the at least one plate.
