Patent number: 10781114Abstract: 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.Type: GrantFiled: September 11, 2017Date of Patent: September 22, 2020Assignee: NATURAL SCIENCE, LLCInventor: Arden A Warner
