A system for separating the components of an incoming oil-water mixture includes two electrode sets, one set arranged to apply an electrostatic field to an oil layer residing within a separator vessel and the other set arranged to apply an electrostatic field to the interface emulsion layer residing within the separator vessel. The first set of electrodes is in communication with a high voltage power source that ranges from 1 to 60 kV; the second set of electrodes is in communication with a low voltage power source that is no greater than 5 kV. Each set of electrodes may also be in communication with a second voltage source to provide increased power to promote effective coalescence. The system may also include power electronics to produce a variable amplitude and a variable frequency voltage supply to one or both electrode sets. | ||||||

Embodiments discussed herein relate to systems and methods for separating two or more phases of an emulsion or other mixture. The methods include providing the mixture with a net and unipolar charge (e.g., such that adjacent droplets therein acquire net and unipolar charges), thereby enhancing coalescence of like-phase droplets therein and producing, or enhancing the production of, two or more consolidated phases; and collecting the two or more consolidated phases. | ||||||
226 | Systems and processes for separating emulsified water from a fluid stream | US14874501 | 2015-10-05 | US10100263B2 | 2018-10-16 | Robert Paul Adamski; Gregory Kent Bethke; Gautan Chandrakanth Kini; Santhosh Kumar Shankar |
Decreasing the water content of an organic phase can often be desirable, but low water levels can be difficult to achieve at high fluxes when the 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. A biphasic mixture comprising continuous phases of the organic component and the bulk aqueous phase is formed within the coalescence zone and subsequently removed from the vessel. | ||||||

The flash vessel and/or the low pressure degasser may employ an inlet cyclonic distributor and demisting cyclones, while the electrostatic treater may employ DUAL FREQUENCY® technology. The separator vessel may be a single horizontal two-phase separator/degasser or two vertical two-phase separator/degassers that operate in parallel with each receiving approximately 50 percent of the incoming produced water stream. The final outlet stream preferably contains no more than 0.5 BS&W and 285 milligrams per liter salt. | ||||||
228 | Crude oil storage tank with electrostatic internals to dehydrate crude oil within a process train of a floating production storage and offloading installation | US14977880 | 2015-12-22 | US09914073B2 | 2018-03-13 | Marcus D.

A process train for a floating production storage and offloading installation includes a crude oil storage tank that is equipped with at least one set of electrostatic internals arranged to provide a treatment flow path isolated from a surrounding volume of the electrostatic separator section of the tank. An oil-and-water stream or mixture entering the set of electrostatic internals travels along the treatment flow path and is subjected to an electric field. The treatment flow path is in an upwardly direction toward the oil outlet section and in a downwardly opposite direction toward the water outlet section of the tank. Employing electrostatic internals within the tank permits an allowable inlet water content into the tank of up to 80%, significantly reducing the required topside processing equipment. | ||||||

231 | CAPTURING SPECIFIC NUCLEIC ACID MATERIALS FROM INDIVIDUAL BIOLOGICAL CELLS IN A MICRO-FLUIDIC DEVICE | US15105849 | 2014-12-18 | US20170021366A1 | 2017-01-26 | Kevin T. Chapman; Eric D. Hobbs; Steven W. Short; Mark P. White; Daniele Malleo |
Individual biological cells can be selected in a micro-fluidic device and moved into isolation pens in the device. The cells can then be lysed in the pens, releasing nucleic acid material, which can be captured by one or more capture objects in the pens. The capture objects with the captured nucleic acid material can then be removed from the pens. The capture objects can include unique identifiers, allowing each capture object to be correlated to the individual cell from which the nucleic acid material captured by the object originated. | ||||||

An apparatus and method for separating water from an oil-and-water mixture includes at least two elongated separator vessels oriented at an incline and connected to one another so that an upwardly flowing oil predominant fluid passes from the first separator vessel to the second separator vessel where further electrostatic separation of water from the oil predominant fluid occurs. Each vessel has an electrode at its upper end preferably connected to a different voltage source. The inlet to each vessel is located relative to the electrode to provide an up flow or a down flow vessel. Additionally, the first vessel may be at a different elevation than the second vessel. An additional vessel may be included with output from the first vessel bypassing the additional vessel, the second vessel, or both. Baffles may be added in the water collection portion of each vessel to reduce turbulence and settling distance. | ||||||

An active method for decanting the dispersed phase in the continuous phase of an emulsion. According to the method, repulsive forces created by an electric field are used on the drops constituting the dispersed phase. The electric field scans the reservoir containing the emulsion, enabling the dispersed phase to be concentrated in a determined region of the reservoir, for the recovery and/or analysis of the emulsion. A device implements the method. | ||||||

Method for oil removal. The method includes adding a magnetizable material, with or without appropriately selected surfactants, of order micron (having no net magnetization) or nanometer size to magnetize the oil or water phase by either making a ferrofluid, magnetorheological fluid, a magnetic Pickering emulsion (oil in water or water in oil emulsion), or any other process to magnetize either oil or water phases. The magnetized fluid is separated from the non-magnetic phase using novel or existing magnetic separation techniques or by permanent magnets or electromagnets thereby separating oil and water phases. The magnetized particles are separated from the magnetized phase using novel or existing magnetic separation techniques to recover and reuse the particles. The two magnetic separation steps can be repeated to further increase recovery efficiency of the liquid phases and the magnetizable particles reused in this continuous process. | ||||||
