  • 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: 8440154
    Abstract: A process has been developed to selectively dissociate target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism. Target molecules include ammonia for waste reclamation and treatment, PCB remediation, and targeted drug delivery.

  • Patent number: 8202500
    Abstract: A process has been developed to selectively dissociate target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism. Target molecules include ammonia for waste reclamation and treatment, PCB remediation, and targeted drug delivery.

  • Patent number: 8197857
    Abstract: A method for the elimination of carbon dioxide from waste gases includes the following steps. First, waste gases, which include carbon dioxide, are provided from a source for waste gases. Next, the waste gases are contacted with an absorbent composition that includes perfluorodecalin solution. The waste gases, especially the carbon dioxide, are then absorbed by the absorbent composition. The absorbent composition thereby absorbs the waste gases to eliminate the carbon dioxide.

  • Patent number: 8158089
    Abstract: Particular aspects provide a method for recovering phosphate, comprising: obtaining an effluent or wastewater, etc. having calcium-sequestered phosphate; adding to the effluent or wastewater a calcium chelating or sequestration agent suitable to chelate or sequester Ca++ ions from the calcium-sequestered phosphate to facilitate release of phosphate from the calcium-sequestered phosphate; transferring, facilitated by said Ca++ ion capture and in the presence of sufficient concentrations of NH4+ and Mg2 ions, of the phosphate into struvite (magnesium ammonium phosphate hexahydrate or MgNH4PO4.6H2O), or hydrated magnesium ammonium complex of phosphate; and recovering the struvite, or the formed hydrated magnesium ammonium complex. Preferably, the method further comprises acidification of the effluent or wastewater to facilitate release of Ca++ ions from the calcium-sequestered phosphate and chelation of sequestration of the Ca++ ions by the calcium chelating or sequestration agent.

  • Patent number: 8080404
    Abstract: Compositions and methods for enzymatic decontamination by inactivation of Hazardous agents are provided. Hazardous agents of microbial and chemical origin can be neutralized by H2O2. The methods described herein provide for enzymatic production of H2O2 in situ using oxidoreductase enzymes that use oxygen as an acceptor and their alcohol substrates. The enzymatically produced H2O2 and corresponding aldehydes have potent antimicrobial properties. The enzymatically produced H2O2 also can detoxify chemical agents in situ. The decontaminating power of the oxidoreductase enzymes that use oxygen as an acceptor may be amplified by addition of reagents, such as acetyl donors or base catalysts that, in the presence of H2O2, yield peroxy acid derivatives and hydroperoxy anions. Such derivatives can neutralize biological and chemical agents, thus providing a broadly applicable decontamination method.
