  • Patent number: 10011505
    Abstract: An apparatus and method isolating ion generation from target metal precipitation and flocculation rely on an ion generator and a precipitation reactor distinct, separated, optimized, and otherwise independent from each other as to flow regime and contained fluid at all times. No co-habitation of ion generation and precipitation nor their flow regimes is permitted in a single unit. Plug flow at hyper turbulence in the ion generator contrasts with quiescent to laminar flows in the precipitation reactor. Coating sacrificial anodes is avoided by avoiding over driving currents for ionization at the anode. A precipitation reactor is optimized by a dwell time effective to precipitate and flocculate heavy target metal precipitants and sacrificial ions relying on weak forces not tolerated by inertial forces in the ion generator.

  • Patent number: 9023214
    Abstract: The invention provides a method and apparatus for creating plasma particles and applying the plasma particles to a liquid. Liquid feedstock (e.g., water and/or hydrocarbons mixed with biomass) is pumped through a pipeline; the single-phase stream is then transformed into a biphasic liquid-and-gas stream inside a chamber. The transformation is achieved by transitioning the stream from a high pressure zone to a lower-pressure zone. The pressure drop may occur when the stream further passes through a device for atomizing liquid. Inside the chamber, an electric field is generated with an intensity level that exceeds the threshold of breakdown voltage of the biphasic medium leading to a generation of a plasma state. Furthermore, the invention provides an energy-efficient highly adaptable and versatile method and apparatus for sanitizing water using plasma particles to inactivate biological agents contaminating water.

  • Patent number: 8961651
    Abstract: Energy consumption of the society is increasing due to expanding economic activity and increasing population. As greater consumption of energy generates more air pollution, there is an ongoing need to find better methods of reducing pollutants in terms of effectiveness and reduced energy consumption. The solution proposed in this disclosure takes advantage of electrical characteristics such as electron affinity and dipole moment. There are many pollutants which exhibit positive electron affinity. Such a pollutant can be easily converted to a negative ion by providing an extra electron. Many of the pollutants have dipolar charge distributions which facilitate electrical interactions with charges. If one of the pollutants becomes charged, it can attract other pollutants which are dipoles to form clusters of pollutants. Furthermore, charged clusters are responsive to electric and magnetic fields. For example, they can be separated from the rest of the flue gas by manipulating with such fields.

A light source activates the photocatalytic particles, which oxidize the contaminants to purify the gas. The purified gas exits via the wide of end of the chamber. Cyclonic action forces the photocatalytic particles out of the chamber's narrow end to a recycling conduit, which conveys the photocatalytic particles back into the chamber.

  • Patent number: 8328997
    Abstract: This invention relates to the design of a process by intermittent dielectric heating combined with a recycling system. This process consists in subjecting reagents to electromagnetic waves selected in the frequencies ranging between 300 GHz and 3 MHz intermittently using a recycling system. This process enables the treatment of oils that are hardly absorbent as well as great investment savings. This process enables operation on different scales, whether in laboratories, on a semi-industrial or industrial scale, without forfeiting the advantages of continuous dielectric heating.

    Abstract: Superior hydroxyls are provided which have effects on organic and inorganic compounds and/or pollutants over substantial periods of time and/or at substantial distances from where the superior hydroxyls are generated. Also provided is a hydroxyl generator, in which UV-lamps are positioned such that the coronas which they produce when emitting UV-radiation fill substantially all of the interior space of the hydroxyl generator. The coronas overlap each other by a maximum amount of between 5% and 25% of the radius of each corona.

  • Patent number: 8192704
    Abstract: A method of extracting uranium from spent nuclear fuel (SNF) particles is disclosed. Spent nuclear fuel (SNF) (containing oxides of uranium, oxides of fission products (FP) and oxides of transuranic (TRU) elements (including plutonium)) are subjected to a hydrogen plasma and a fluorine plasma. The hydrogen plasma reduces the uranium and plutonium oxides from their oxide state. The fluorine plasma etches the SNF metals to form UF6 and PuF4. During subjection of the SNF particles to the fluorine plasma, the temperature is maintained in the range of 1200-2000 deg K to: a) allow any PuF6 (gas) that is formed to decompose back to PuF4 (solid), and b) to maintain stability of the UF6. Uranium (in the form of gaseous UF6) is easily extracted and separated from the plutonium (in the form of solid PuF4). The use of plasmas instead of high temperature reactors or flames mitigates the high temperature corrosive atmosphere and the production of PuF6 (as a final product).
