Abstract

Ozone/oxygen gas is mixed with treated seawater at 30% quality foam and injected to the wellhead at the sea floor. At the seafloor, a tank mixing eductor would be used to mix high pressure oxygen bubbles with the oil contaminated seawater by shearing the oil globs into small oil droplets allowing the new surface area to immediately react with the dissolved ozone/oxygen in the seawater. The ozone/oxygen admixture creating an attraction force between the droplets and the oxygen bubbles. As the droplets and bubble rise, they form larger spherical top-hat bubbles that rise faster in the seawater. In the preferred embodiment, the eductor employs a cone shape flow to direct a significant amount of the oil plume into a predictable area that can then be skimmed mechanically for harvesting or destruction.
