  • Patent number: 9878300
    Abstract: A system and method for cleaning sulfur and other pollutants from bunker oil to be used for fuel in large cargo ships is described. Preferably, the system includes two or more stages having a mixer to create an emulsion of oil and water. One or more treatment chemicals are added to the water before it is mixed with the oil in order to assist in separating the sulfur from the oil and freeing it up so that it can combine with various other molecules present in the water or be dissolved in the water. The emulsion may pass through a microcavitation chamber as well as an electrolysis reactor chamber in order to further clean the fuel oil by removing additional sulfur content. The clean fuel is sent to a fuel service tank for use in a diesel engine combustion cycle.

A parallel plate capacitor can be connected after the salt sponge to remove remaining salt ions. The salt sponge is a nanoporous, high surface area carbon scaffold to which crown ethers are attached. A power supply is connected to the salt sponges for applying a bias voltage to regenerate the salt sponges. A chlorine treatment unit can be connected after the parallel plate capacitor. A method of purifying sea water using the apparatus also is disclosed.

  • Publication number: 20130026039
    Abstract: A method for removing soot, sludge, varnish and other insoluble particulates from engine oil, the method including the steps of: disposing an oil containing the particulates between a pair of electrodes, wherein one of the electrodes is a collecting electrode; wrapping a surface of the collecting electrode with a media, wherein the media is configured to collect a portion of the particulates drawn towards the collecting electrode; applying a direct current to the electrodes for a period of time to generate an electric field, wherein the electric field causes a portion of the particulates to agglomerate in the media; and removing the media and the portion of particulates agglomerated in the media to reduce the amount of soot particles in the oil.

  • Patent number: 8293091
    Abstract: Electrostatic filters, systems and methods having separate positively and negatively charged filter elements within electrically isolated filter tanks for electrostatically filtering particles from a fluid flow. Both positive charged connections biased to earth ground and negative charged connections biased to earth ground are made to the respective positive and negative charged filter elements, along with triboelectric induced charge accumulations from the fluid flow, for separating charged particles within the fluid flowing parallel through these oppositely charged filter elements. Variable resistors of a power supply connected to such filters, systems and methods provide for controlling and adjusting for any undesired voltage excesses and/or shortfalls within these filter tanks so that the fluid flowing exiting these filter tanks is unbiased to generate a filtered fluid having balanced electrostatic charges.

  • Patent number: 8282880
    Abstract: A bottle, a system and a method sterilize a liquid. The bottle has an interior to hold the liquid and an ultraviolet light emitting lamp that extends into the interior. A cord may be attached to the bottle so that pulling the cord may power the ultraviolet light emitting lamp and/or charge a battery used to power the ultraviolet light emitting lamp. The bottle may have a status light that indicates that the ultraviolet light emitting lamp may have an amount of power equal to or greater than a threshold value, such as, for example, an amount of power necessary for the ultraviolet light emitting lamp to operate for ninety seconds. The bottle may have a removable lid located opposite to the ultraviolet light emitting lamp.

  • Patent number: 8211284
    Abstract: A separating system for separating a fluid mixture incorporates a smart surface having reversibly switchable properties. A voltage is selectively applied to the smart surface to attract or repel constituents of a fluid mixture, such as oil and water produced from a hydrocarbon well. The smart surface can be used in a conditioner to increase droplet size prior to entering a conventional separator, or the smart surface and other elements of the invention can be incorporated into an otherwise conventional separator to enhance separation. In a related aspect, a concentration sensor incorporating smart surfaces senses concentration of the fluid mixture's constituents.
