  • Patent number: 10597589
    Abstract: Low-water content organic phases can be difficult to achieve at high fluxes when water is present in an emulsified form, such as in a water-in-oil emulsion. Processes for de-emulsifying a fluid stream containing emulsified water, such as water-in-crude oil emulsions, include introduction of the fluid stream into a vessel that defines a coalescence zone. The vessel is configured to provide for simultaneous application of a centrifugal force and an electric field to the fluid stream within the coalescence zone. The simultaneous application of the centrifugal force and the electric field to the fluid stream provides for the coalescence of a portion of the emulsified water into a bulk aqueous phase. Continuous phases of the organic component and the bulk aqueous phase form in the coalescence zone and are separately removed from the vessel. The bulk aqueous phase is removed from the underside of the vessel.

  • Patent number: 10207202
    Abstract: An apparatus and method for separating water from an oil-water influx are provided. The apparatus includes a separation vessel having an inlet, an oil collection portion at its upper end, and a water collection portion at its lower end. Multiple high voltage tubes, each containing an electrode, are located within the oil collection portion. These high voltage tubes are staggered in length and held in place by perforated plates. The oil-water influx flows through the inlet of the vessel into the high voltage tubes, where it is subjected to an electrostatic field. The electrostatic field causes water droplets in the influx to coalesce and form a water out-flux which flows downwardly into the water collection portion of the vessel. The remaining stream of dehydrated oil flows upwardly to the upper outlet end. The oil collection portion of the separation vessel may be oriented vertically or at an angle.

  • Patent number: 8663444
    Abstract: Prolongation of the lifetime for reduced water is attempted. Production water that presents alkalinity is produced by utilizing raw water with ionized metallic minerals being dissolved therein and hydrogen gas H2. When inpouring the hydrogen gas together with the raw water into an electromagnetic portion in the apparatus, the hydrogen gas is bubbled and ionized to produce ions. The gas bubbles of the ionized hydrogen-ions are miniaturized. By making a metallic mineral as a core, hydrides (H?), which are negative ions in the hydrogen ions, coordinate on the periphery of that core. The metallic minerals which are complex-ionized (complex-ionized metallic minerals) based on a fact that the hydrides coordinate are dissolved in the water stably for long period of time, so that production water which presents alkalinity, that is, reduced water can be obtained. The reduced water can be utilized as drinking water. A metal container is preferable for a refilling container.

  • Patent number: 8460532
    Abstract: The present invention provides a new method and apparatus/system for purifying ionic solutions, such as, for example, desalinating water, using engineered charged surfaces to sorb ions from such solutions. Surface charge is applied externally, and is synchronized with oscillatory fluid movements between substantially parallel charged plates. Ions are held in place during fluid movement in one direction (because they are held in the electrical double layer), and released for transport during fluid movement in the opposite direction by removing the applied electric field. In this way the ions, such as salt, are “ratcheted” across the charged surface from the feed side to the concentrate side. The process itself is very simple and involves only pumps, charged surfaces, and manifolds for fluid collection.

  • Patent number: 8293091
    Abstract: Electrostatic filters, systems and methods having separate positively and negatively charged filter elements within electrically isolated filter tanks for electrostatically filtering particles from a fluid flow. Both positive charged connections biased to earth ground and negative charged connections biased to earth ground are made to the respective positive and negative charged filter elements, along with triboelectric induced charge accumulations from the fluid flow, for separating charged particles within the fluid flowing parallel through these oppositely charged filter elements. Variable resistors of a power supply connected to such filters, systems and methods provide for controlling and adjusting for any undesired voltage excesses and/or shortfalls within these filter tanks so that the fluid flowing exiting these filter tanks is unbiased to generate a filtered fluid having balanced electrostatic charges.

  • Patent number: 8211284
    Abstract: A separating system for separating a fluid mixture incorporates a smart surface having reversibly switchable properties. A voltage is selectively applied to the smart surface to attract or repel constituents of a fluid mixture, such as oil and water produced from a hydrocarbon well. The smart surface can be used in a conditioner to increase droplet size prior to entering a conventional separator, or the smart surface and other elements of the invention can be incorporated into an otherwise conventional separator to enhance separation. In a related aspect, a concentration sensor incorporating smart surfaces senses concentration of the fluid mixture's constituents.

  • Patent number: 8062517
    Abstract: A method and system for removing from an aqueous system which is contaminated therewith: (1) mercury present as colloids, ions and/or organically bound compounds, and (2) hydrocarbons solubilized, dispersed, and/or emulsified in the said system. Pursuant to the invention the aqueous system to be treated (such as “produced water”) is passed successively through three filtration stages. The first filtration stage is provided with absorption media which effects reduction/removal of dispersed organically bound mercury species and of the dispersed and partially dissolved hydrocarbon phases, as well as of some colloidal mercury and other dissolved metallic species. The second filtration stage utilizes a salt modified reticulated granular filtration media for reduction/removal of slightly dissolved hydrocarbon phases, mercury in colloidal and ionic form and other dissolved metals.

  • Patent number: 7981268
    Abstract: The present invention provides a new method and apparatus/system for purifying ionic solutions, such as, for example, desalinating water, using engineered charged surfaces to sorb ions from such solutions. Surface charge is applied externally, and is synchronized with oscillatory fluid movements between substantially parallel charged plates. Ions are held in place during fluid movement in one direction (because they are held in the electrical double layer), and released for transport during fluid movement in the opposite direction by removing the applied electric field. In this way the ions, such as salt, are “ratcheted” across the charged surface from the feed side to the concentrate side. The process itself is very simple and involves only pumps, charged surfaces, and manifolds for fluid collection.

  • Patent number: 7901570
    Abstract: The present invention describes a system and method for supplying electrical power to a device, such as a filter element, located within a housing. In one embodiment, a conductive coil is embedded into the housing base, and a second coil is embedded into the filter element. Current is then passed through the coil in the housing base. Through induction, a current is created in the second coil in the filter element, in much the same way as a transformer functions. This inductive field may interfere with the operation of the various electronic functions, such as communications, sensing or other activities. To overcome this issue, an energy storage component, such as a capacitor, is included in the filter electronics. In this way, the power generated by the inductive field can be stored, and used when the inductive field is no longer present.
