Patent number: 7992641Abstract: 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: GrantFiled: September 20, 2010Date of Patent: August 9, 2011Assignee: Nitra-Gen LLCInventors: Donald O. Hitzman, D. Michael Dennis

Patent number: 5750392Abstract: Hydrogen sulfide present in an aqueous system is removed and the production of hydrogen sulfide by sulfate-reducing bacteria (SRB) is eliminated by introducing into the system nitrite and nitrate and/or molybdate ions, whereby denitrifying microorganisms outcompete the sulfate-reducing bacteria for the available carbon nutrients, thus preventing the SRB from producing hydrogen sulfide and the nitrite along with the denitrifying microorganisms remove hydrogen sulfide already present in the system. The system which contains the denitrifying microorganisms and which is essentially free of hydrogen sulfide can enhance oil recovery by means of a microbial enhanced oil recovery mechanisms.Type: GrantFiled: September 15, 1994Date of Patent: May 12, 1998Assignee: Geo-Microbial Technologies, Inc.Inventors: Donald O.

Patent number: 5509319Abstract: A pipetter is connected to a hypodermic needle by an adapter. The adapter includes a conduit with male and female ends and a predetermined volume. The female end of the conduit is dimensioned to receive the end of the pipetter to form a substantially air-tight friction fit. The male end of a conduct is dimensioned to be inserted into the needle holder to form a substantially air-tight friction fit. The volume of the conduit is greater than a volume of the fluid to be transferred. The adapter allows one to combine the advantages of a hypodermic needle with the superior volumetric measuring capabilities of a pipetter, while eliminating the waste associated with disposable syringes.Type: GrantFiled: June 21, 1994Date of Patent: April 23, 1996Assignee: Geo-Microbial Technologies, Inc.Inventor: Donald O.

Patent number: 4556635Abstract: The concentration of a C.sub.1 to C.sub.4 alcohol in an essentially water immiscible organic system is accurately determined by a simple and quick process. A sample of the water immiscible organic system containing less than about 0.01% (W/V) of the alcohol is contacted with an aqueous layer of alcohol oxidase immobilized on an electrode for measuring dissolved oxygen content. Ethanol in the water immiscible organic system partitions into the aqueous layer where alcohol oxidase catalyzes oxidation of the alcohol. Oxygen consumed during the oxidation is measured by the electrode, and the concentration of alcohol determined therefrom. To obtain less than about 0.01% alcohol in the sample, the sample may be diluted with the water immiscible organic system.Type: GrantFiled: August 29, 1983Date of Patent: December 3, 1985Assignee: Phillips Petroleum CompanyInventors: Donald O.
