  • Publication number: 20140163299
    Abstract: Apparatuses for controlling emissions of carbon capture facilities and associated methods are disclosed that generally involve a chamber defining at least one wash-water packing. The exemplary apparatuses further include at least one washwater return line, a UV treatment zone and a hydrogen peroxide treatment zone. The UV treatment zone generally receives UV energy sufficient to substantially destroy a first emission compound and the hydrogen peroxide treatment zone generally receives a hydrogen peroxide medium sufficient to substantially oxidize a second emission compound to a less volatile final product. An alternative exemplary apparatus generally involves a UV treatment zone and an ozonation treatment zone, further including a hydrogen peroxide treatment zone applied within the ozonation treatment zone. The exemplary methods generally include applying at least one of a UV treatment, a hydrogen peroxide treatment and an ozonation treatment.

  • Publication number: 20110160512
    Abstract: The various embodiments herein provide a method of preparation of a nano-material for dechlorination of polychlorobiphenyls (PCB) from oil. The method involves preparing a modified bentonite prepared by treating with hexadecyl pyridinium bromide surfactant and dispersing the modified bentonite in cyclohexane. Aqueous solutions of metal ion such as Cadmium Nitrate or Zinc Nitrate and sulfide ions such as sodium sulfide are added alternately to obtain metal sulphide nano-particles. zinc nitrate is more preferable. The method of dechlorination of polychlorobiphenyls from oil involves irradiating a mixture of oil, nano-material and a solvent such as toluene under UV light for 2-6 h. A nano-material including a modified bentonite with a mono-layer of surfactant and metal sulphide nano-particles such as ZnS and CdS for remediation of oil containing PCB, is also provided.

  • Patent number: 7837966
    Abstract: Ozone and, if necessary, water is added to an exhaust gas, such as air, containing hydrogen- and carbon-containing molecules of a pollutant. The exhaust gas is then continually flowed into one or more oxidizing reaction chamber modules. In the reaction chamber(s) the ozone- and water-containing gas is subjected to intense ultraviolet radiation (wavelength of 254 nm) to promote the formation of hydroxyl radicals to oxidize the pollutant molecules to carbon dioxide and water. The continually discharged gas is analyzed for residual ozone and hydrocarbon content and the analytical data used in feedback control of ozone addition and UV radiation intensity.
