A water-in-hydrocarbon emulsion includes a water phase, a hydrocarbon phase and a surfactant, wherein the water phase is present in an amount greater than or equal to about 5% vol. with respect to volume of the emulsion, and the water phase and the surfactant are present at a ratio by volume of the water phase to the surfactant of at least about 1. A method for preparing the emulsion is also provided.

An apparatus for characterizing dynamic stability of an emulsion includes a test vessel, a gap within the test vessel defined between a stationary surface and a moving surface; and an inlet for feeding an emulsion through the gap within the test vessel, whereby dynamic stability of the emulsion can be characterized based upon cycles of flow through the test vessel. Methods for characterizing dynamic stability are also disclosed.

A method for on line recovery of oil from an oil in water emulsion spilled in water includes the steps of: obtaining a stream of recovered material including an oil in water emulsion and water; inducing a gas into the stream and applying shear so as to provide a mixture wherein oil from the oil in water emulsion is adhered to bubbles of the gas; passing the mixture to a flotation compartment for allowing the oil adhered to the bubbles to rise to a surface of the mixture; and removing the oil from the surface of the mixture.
