  • Patent number: 10988390
    Abstract: A reactor system for reacting liquid phase chemical species in a liquid includes a reactor vessel for containing the liquid phase and a gas phase. The reactor vessel can have a gas injection port, a gas exit port, and a liquid-gas interface location within the reactor vessel. A pulsed discharge cathode and anode are provided for creating a pulsed discharge electric field at the liquid-gas interface location. A pulsed discharge power supply delivers a pulsed power input to the pulsed discharge cathode and anode, and thereby creates a plasma comprising ions at the liquid-gas interface location. A secondary electric field source is provided for directing a secondary electric field transverse to the liquid-gas interface. The secondary electric field will drive some of the ions from the gas phase into the liquid phase to react with the liquid phase chemical species. A method for reacting a liquid phase chemical species is also disclosed.

  • Patent number: 10717662
    Abstract: A process for the simultaneous removal of iron and phosphate ions from a chlorinated hydrocarbon waste stream, such as a waste stream derived from a process for manufacturing 1,1,1,3,3-pentachloropropane (HCC-240fa) and/or 1,1,1,3-tetrachloropropane (HCC-250fb). The waste stream contains at least one of chlorinated hydrocarbons, tributyl phosphate (TBP) and/or triethyl phosphate (TEP), iron, FeCl2 and/or FeCl3, a TBP-FeCl2 complex and/or a TBP-FeCl3 complex, and a TEP-FeCl2 complex and/or a TEP-FeCl3 complex, and is subjected to thermal oxidation to generate a second, aqueous waste stream containing at least one of hydrogen chloride (HCl), FeCl3 and/or FeCl2, and H3PO4. The second waste stream is exposed to a base to generate a precipitate including at least one insoluble compound selected from the group consisting of FePO4, Fe(OH)3, and Ca3(PO4)2, and the precipitate is separated from the second waste stream to produce a liquid phase including only trace amounts of iron and phosphate ions.

  • 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: 7677185
    Abstract: The invention is a system and method for neutralizing fluid chemical waste products that result from a chemical production process and are collected from the production line. The invention comprises a pyrolysis/reaction chamber into which the fluid chemical waste is pumped through an atomizer. The jet of small droplets of liquid waste that is formed by the atomizer effectively contacts the plasma stream created by a plasma torch. When the droplets contact the plasma stream the molecules of the waste from which the droplets are composed are dissociated into atoms and/or ions. These atoms and ions move out of the immediate region of the plasma stream and recombine to form a mixture of product gases which exits the chamber. The product gases then enter a post-pyrolysis subsystem, which is designed to neutralize and/or collect the components comprising the mixture of product gases.

  • Patent number: 7381380
    Abstract: A system and method for the removal of metals such as mercury from a gas stream. The method involves contacting a gas stream containing the target metals with reactive chemical species generated in a plasma device. The metal to be removed is chemically converted into forms enabling capture in either conventional particulate removal devices or in a wet scrubber for the capture of a soluble chemical species.

  • Patent number: 7220396
    Abstract: There are disclosed various processes, apparatuses and systems for treating a halogen-containing gas such as F2 that involve generating a plasma in order to reduce chemically the halogen-containing gas into products that are more environmentally manageable. According to a particular embodiment, a reducing agent is mixed with the halogen-containing gas to produce a feed gas mixture and a non-thermal plasma is generated in the feed gas mixture in the presence of liquid water. According to another embodiment, a vaporized portion of a liquid reducing agent is mixed with the halogen-containing gas to produce a reaction mixture and a non-thermal plasma is generated in the reaction gas mixture to reduce the halogen-containing gas.

  • Patent number: 7132584
    Abstract: A method of using high temperature plasma to disintegrate waste containing titanyl phthalocyanine (TiOPc) comprises heating a mixture of titanyl phthalocyanine (TiOPc), a vitrifying material and optionally selected waste soil to a temperature of 1,220° C. to 10,000° C. until the mixture becomes a molten lava. The plasma breaks down the titanyl phthalocyanine and encapsulates the benign products in the lava that is chemically very stable. Since the titanyl phthalocyanine (TiOPc) is disintegrated completely in the process, the titanyl phtbalocyanine (TiOPc) no longer represents a threat to the environmental.

  • Patent number: 7083763
    Abstract: A feed system for loading waste into a fuel gas generator system where the feed system is made of a walled container wherein the outer container back has an outer back hole and the inner container back has an inner back hole, and wherein the holes are aligned and a piston penetrates the holes, wherein the piston is connected to a plate moveably disposed in the container, wherein the piston is connected to sealable opening locks to apply pressure and retract the plate to a position against the back thereby providing a loading chamber to insert waste, a second piston connected to the door retracts the door for loading waste, at least one inert gas injector mounted to the container for flooding the loading chamber with inert gas, a liquid cooling system disposed in the walls of the container, and a controller for operating the locks, doors and sealable opening.
