The present method for producing a high stability, low emission, invert fuel emulsion composition comprises blending additives having a surfactant package with a hydrocarbon petroleum distillate fuel in an in-line blending station to create a composition. The surfactant package includes a primary surfactant, a block copolymer, and a polymeric dispersant, and the hydrocarbon petroleum distillate fuel is a continuous phase of the emulsion. The method also comprises blending purified water with the composition in a second in-line blending station to produce a second composition and aging the second composition in a reservoir to produce an aged composition and passing the aged composition through a shear pump to a storage tank.

Stabile invert fuel emulsion compositions and method of making

An improved method for producing highly stabile aqueous fuel emulsions. The method provides for selectively combining prescribed quantities of diesel fuel, purified water, alcohol, and an additive package and emulsifying the fuel mixture using a high shear mixer. The optimum viscosity and stability in the aqueous fuel emulsion is achieved by bypassing a selected quantity of the fuel emulsion around the high shear mixing device such that the final fuel emulsion includes a bi-modal droplet size distribution having droplet sizes less than about 15 microns in size. Additional stability and performance features of the aqueous fuel emulsion are attributed to the contents of the additive package that includes a combination of surfactants, lubricity additive, cetane improvers, citric acid, and methanol wherein each of the various additives may perform multiple functions.
