  • Patent number: 10266438
    Abstract: Provided is a method for reducing COD of wastewater with improved utilization efficiency of ozone. The method achieves an objective by adding agents for removing hydroxyl radical scavengers produced by base-catalyzed ozone advanced oxidation to wastewater. The addition of calcium ion, barium ion, etc. to a base-catalyzed ozonation system makes the hydroxyl radical scavengers form precipitates, separated from water and lose the capability of scavenging hydroxyl radicals, thereby enhancing ozone utilization efficiency. Furthermore, calcium ion, barium ion, etc. form precipitates with partial organic acids yielded in the wastewater ozonation and are separated from water, hence diminishing ozone consumption and indirectly improving the ozone utilization efficiency in the wastewater treatment.

  • Patent number: 9416029
    Abstract: A biocidal water purification apparatus exposes water to radiation to eliminate viable species. A housing forms a path for water to flow from an inlet to an outlet along a flow path through a treatment zone at which the water is subjected to radiation from a source of radiation, such as beta particles from strontium-90. The exposure to radiation is enhanced using a narrow water flow path lined with the source, especially on oppositely interleaved plates with triangular cross sections, spaced by about 0.25 inch to produce an elongated zigzag path traversed by the water, for example by vertical gravity feed. Additional aspects include other forms of radiation and pre- and post-treatment water treatment or filtration stages and alternatives for continuous, batch and timed-residence water flow management.

  • Patent number: 9273542
    Abstract: In a method for controlling interface level between a liquid inventory and an overlying steam chamber in a subterranean petroleum-bearing formation, an inflow relationship is developed to predict the vertical position in a gravity field of the interface between the two fluids (liquid and steam) with a density contrast relative to a horizontal producer well. The inflow relationship is applied to producer well completions by designing the completion to raise or lower sand face pressures according to mobility variations over the horizontal length of the well. This pressure distribution will affect liquid levels according to the inflow relationship. The completion can include tubing-conveyed or liner-conveyed flow control devices to create flow network that provides a customized sand face pressure distribution. Axial flow relationships between adjacent locations along the producer well may be modeled in order to develop an axial flow network to facilitate estimation of liquid levels at selected locations.

The method includes defining one or more operational protective zones in the hot water system. One or more of the operational protective zones includes an oxidation-reduction potential probe that is operable to measure a real-time oxidation-reduction potential in the hot water system at operating temperature and pressure. The probe transmits the measured real-time potential to the controller, which assesses and interprets the transmitted potential to determine whether it conforms to an oxidation-reduction potential setting. If the measured potential does not conform the oxidation-reduction potential setting, the controller is operable to feed or remove one or more active chemical species into or from the hot water system and further operable to change at least one system parameter.

  • Patent number: 8968576
    Abstract: A method of treating contaminated air, gas and surfaces is accomplished through the nebulization of gas and/or liquid oxidants through a field of electromagnetic radiation or sonic waves. The contaminated gas and/or liquid streams are blended with gaseous and/or liquid oxidants by the nebulizer and directly injected in the energy field. Free radicals produced from oxidants in the presence of the energy field instantaneously oxidize a large effective surface area of the contaminated media. Surfaces are treated more efficiently with the energy field situated directly above and parallel to but not on the surface; a high-frequency energy field may be used to create a large concentration of free radicals without damaging the surface in a collimated beam of the field situated parallel to the surface. A catalyst may be employed at the tip (i.e. discharge orifices of gas and/or liquid) of the nebulizer or blended into the nebulized cloud to increase the formation of free radicals.

Further, a method of reclaiming a formate brine may include lowering the pH of the spent formate brine fluid comprising water-soluble polymers; increasing the pH of the spent formate brine fluid to initiate precipitation of materials solubilized in the fluid; treating the fluid with an oxidizing agent to break down remaining water-soluble polymer; and recovering at least a portion of the formate brine.

  • Publication number: 20140311990
    Abstract: A turbulence inducing device is described. Embodiments of the device include a nozzle (135), a vessel assembly (110), and an obstructer (140). The vessel assembly typically includes an open ended main channel (115) surrounded by a housing. In typical operation, fluid under positive pressure is forced through the nozzle into the main channel. Disposed at the main channel outlet, the obstructer is adapted to deflect the flowing fluid and induce turbulence that can result in cavitation when the fluid is a liquid. When the liquid includes water, cavitation can result in production of reactive species that oxidatively modify contaminants in the water. Embodiments of the turbulence inducing device can be used to reduce contamination of produced water, the produced water arising from hydrocarbon extraction or exploration.

  • Patent number: 8852437
    Abstract: A method of producing sterile water from raw water during a production cycle in a production plant P, including adding a disinfectant to the produced sterile water during the production cycle to permanently monitor the condition of the sterile water and/or the production plant, and determining and evaluating a reduction of concentration of the disinfectant directly in the production stream. In a production plant suited for carrying out the method, a sterile sensor is provided directly in the production stream through which the reduction of concentration of the disinfectant added to the produced sterile water can be permanently measured and evaluated to provide a sterility evidence.

  • Patent number: 8840845
    Abstract: Provided herein are systems and methods for the treatment and purification of fluids (e.g., water) using a light-emitting diode (LED) light source. In one embodiment, for example, there is provided a fluid flow conduit having an LED light source and a photo-catalytic material disposed therein. The LED light source emits ultraviolet light with a peak wavelength between about 265 nm and about 400 nm. In operation, the photo-catalytic material absorbs the ultraviolet light from the LED light source, and releases free radicals into the fluid. The free radicals then degrade organic substances (e.g., bacteria) in the fluid.

  • Patent number: 8771593
    Abstract: Disclosed is a method of controlling a real-time oxidation-reduction potential in a hot water system to inhibit corrosion in the hot water system. The method includes defining one or more operational protective zones in the hot water system. One or more of the operational protective zones includes an oxidation-reduction potential probe that is operable to measure a real-time oxidation-reduction potential in the hot water system at operating temperature and pressure. The probe transmits the measured real-time potential to the controller, which assesses and interprets the transmitted potential to determine whether it conforms to an oxidation-reduction potential setting. If the measured potential does not conform the oxidation-reduction potential setting, the controller is operable to feed or remove one or more active chemical species into or from the hot water system and further operable to change at least one system parameter.
