Electromagnetic pulsed-wave system for oil manipulation
10781114 · 2020-09-22 · ·

A method is described for controlling an oil spill by seeding micron-sized magnetizable particles in the oil. Once seeded, particles can form a unique and preferential bond with the oil resulting in creation of a colloidal mixture. This bond forms as a result of a combination of forces including the intermolecular Van der Waal forces. Once this bond is formed, the oil is rendered magnetic and can be controlled and moved in response to a magnetic field. This can include removing oil from water, reducing the diffusion rate of oil on water, magnetically lifting oil from water or nonporous surfaces, as well as separating the magnetic material from the oil.

OIL DISPERSANT EFFECTIVENESS MONITORING

A process is provided for the determination of oil dispersant effectiveness. A submersible dispersant sensing platform is passed across a body of water. The platform has a plurality of sensors including a multichannel fluorometer and a particle size analyser, and each sensor produces an output data stream. The body of water is continuously analysed at a predetermined depth profile below the surface of the body of water. Hydrodynamic and environmental condition data is collected proximate in time and location to the output data from the dispersant sensing platform. The environmental condition data includes one or more of ambient temperature, body or water temperature, salinity of the body of water, wind speed, location, mixing energy of the body of water and derivatives thereof. Oil and dispersant data is provided which includes characteristics of the dispersant and of oil samples prior to the application of the dispersant. The output data stream, the hydrodynamic and environmental condition data, and the oil and dispersant data is processed to generate an indicator of the state of dispersion of the oil and of the oil dispersant efficiency under the hydrodynamic and environmental conditions the oil is exposed to. A system for the determination of oil dispersant efficacy is also provided.

ENHANCED FOAM FRACTIONATION OF OIL PHASE FROM AQUEOUS/OIL MIXED PHASE VIA INCREASED VISCOELASTICITY

The present invention provides improved methods for purifying and/or removing oily particles, and/or contaminants suspended or dissolved in water.
