Patents by Inventor D. Michael Dennis

D. Michael Dennis has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7992641
    Abstract: An electric plasma arc apparatus and method produces nitrogen compounds, solely using ambient air extracted in proximity to the apparatus. The nitrogen compounds are brought into contact with a water processing system, forming nitrate on-site. Hydrogen sulfide present in the water processing system is removed, and the production of hydrogen sulfide by sulfate-reducing bacteria (SRB) is eliminated by introducing nitrate into the system, whereby denitrifying microorganisms, using the nitrate, outcompete the sulfate-reducing bacteria for the available carbon nutrients, thus preventing the SRB from producing hydrogen sulfide. Nitrate ions generated in the water processing system which contains the denitrifying microorganisms can enhance oil recovery by means of microbial enhanced oil recovery mechanisms.
    Type: Grant

  • Patent number: 7604741
    Abstract: An apparatus and method produces nitrate ions on-site from water, natural gas and air extracted in proximity to the apparatus. The apparatus generates nitrate ions and brings the nitrate ions into contact with an aqueous system. Hydrogen sulfide present in the aqueous system is removed and the production of hydrogen sulfide by sulfate-reducing bacteria (SRB) is eliminated by introducing into the system nitrate ions, whereby denitrifying microorganisms, using nitrate, outcompete the sulfate-reducing bacteria for the available carbon nutrients, thus preventing the SRB from producing hydrogen sulfide. Nitrate ions generated by the apparatus and added to the aqueous system which contains the denitrifying microorganisms can enhance oil recovery by means of microbial enhanced oil recovery mechanisms.
