Abstract: A method and apparatus for separating oil from water in a raw mixture in which the mixture enters a separator tank having within it electrodes to which an A.C. voltage is applied to cause separation of the oil and water. In one embodiment, two sets of electrodes extend to different lengths in the tanks with a high voltage being applied to the shorter electrodes and a low voltage to the longer. A valve can be disposed in the water outlet pipe to be opened to drain water whenever the sensed conductivity near the tank bottom exceeds a given value. The tank can be immersed in a larger tank and can be provided with porous walls through which the raw mixture enters and the separated oil and water leave. The electrodes can comprise a center electrode and a plurality of high voltage electrodes disposed about said center electrode with a high voltage then applied between said center electrode and the circumferentially disposed electrodes.

Abstract: AN ELECTRIC TREATER FOR RESOLVING WATER-IN-OIL EMULSION INCLUDING A CLOSED HORIZONTALLY ELONGATED VESSEL CONTAINING AN ELECTRICAL FIELD DEFINED BY HORIZONTALLY-DISPOSED, UPPER IMPERFORATE (ENERGIZED) AND LOWER FORAMINOUS (GROUNDED) ELECTRODES. AN INLET DISTRIBUTOR DIRECTS EMULSION FLOWS LATERALLY BENEATH THE IMPERFORATE ELECTRODE AND TOWARD EACH SIDEWALL OF THE VESSEL. TREATED OIL IS REMOVED FROM ABOVE THE IMPERFORATE ELECTRODE AND COALESCED WATER FROM A BODY OF WATER MAINTAINED BELOW THE FORAMINOUS ELECTRODE. THE IMPERFORATE ELECTRODE IS FORMED OF TRANSVERSE RIGID RIBS HAVVING STRAIGHT AND ARCUATE SECTIONS AND LONG PIECES OF THIN METAL (CORRUGATED) SHEETING INTEGRALLY SECURED INTO A MONOCOQUE ELECTTRODE STRUCTURE BEING LIGHTWEIGHT BUT HIGHLY RESISTANT TO TORSIONAL AND LONGITUDINAL BENDING FORCES.

Abstract: An electrowetting coalescing device for coalescing droplets of a dispersed phase within a continuous phase includes an inlet in fluid communication with a first porous layer and a second porous layer. The first porous layer is employed as a first electrode and the second porous layer is employed as a second electrode, and a voltage difference exists between the first porous layer and the second porous layer to thereby create an electric field between the first porous layer and the second porous layer. The electrowetting coalescing device includes an outlet for receiving a fluid having passed through the first porous layer and the second porous layer.

Abstract: A process train for a floating production storage and offloading installation includes a crude oil storage tank equipped with at least one set of electrostatic internals. The set of electrostatic internals are arranged to provide a treatment flow path within the crude oil storage tank oblique to a longitudinal centerline of the crude oil storage tank and through an electric field provided by the set of electrostatic internals. Employing these 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. The process and system also includes, upstream of the tank, two separator vessels arranged in parallel so each receives a portion of an incoming oil-and-water stream, a flash vessel arranged downstream of the two separator vessels, and a degasser vessel. Downstream of the crude oil storage tank is an electrostatic treater.

Abstract: Certain embodiments may generally relate to systems and methods for developing and improving compact electrocoalescers for in-line dehydration of water-in-oil dispersions. A compact electrocoalescer may include a casing, and a plurality of bare or insulated conical-shaped electrodes housed in the casing. The electrodes may include a metal mesh structure. The electrodes may also be truncated at the apex, and alternatively connected to a power supply and ground. The electrodes may further be stacked in a manner such that at least one electrode is at least partially nested within at least another electrode.

Abstract: 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.
