Abstract: A device for separating oil-in-water emulsions and for regenerating cleaning and degreasing baths by electrocoagulation is disclosed. The device for regenerating cleaning and degreasing baths, in particular by separation in an electrophysical cell (3), is characterised in particular in that at least two independent electrode devices (1, 2) have their own independent and separately adjustable current circuits (7-10). The formation of coagulation seeds and the electrocoagulation process may thus be both independently adapted to operation conditions and optimised. The separate circuits for both electrode devices (1, 2) allow the process to be carried out with a small gap between electrodes, low voltages and high current densities, when coagulation seeds are to be formed on the soluble electrodes (2), and allow the electrocoagulation process on the permanent electrodes (1) to be carried out with a larger gap between electrodes, high voltages, high field intensities, low current densities and little gas generation.

Abstract: In an improved process for electrically coalescing water-in-oil emulsions in an AC electrical field at least one insulated electrode (66) is used having a dielectric constant which is at least about 3 and having a hydrophobic surface in contact with the emulsion. This results in faster coalescense of the emulsion than can be obtained with insulated electrodes having a dielectric constant, even if the electrode-emulsion interface were to be hydrophobic. Formation of spongy emulsion and decomposition of the oil phase under the high voltages required for rapid coalescense is minimized and even eliminated.

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.

Abstract: A process train for a floating production storage and offloading installation includes a crude oil storage tank that is equipped with at least one electrostatic separator configured to subject the produced stream that enters the tank to an electric field. The electrostatic separator may include two inclined vessels containing electrostatic internals and in fluid communication with one another. Employing electrostatic separators within the tank can permit an allowable inlet water content into the tank of up to 80%, significantly reducing the required topside processing equipment.

Abstract: A system for desalting crude oil includes delivering a stream of salty crude oil and wash water into a mixing valve, mixing the stream of salty crude oil and wash water through the mixing valve to create a mixed stream of desalted crude oil and salty wash water, delivering the mixed stream of desalted crude oil and salty wash water to a static mixer, and mixing the mixed stream of crude oil and wash water in the static mixer. Within the static mixer, the mixed stream is mixed in a coalescing regime to coalesce smaller droplets of water into larger droplets of water. The mixed stream is subjected to an electric field to cause additional coalescence before being directed to a desalter where the salty wash water is separated from the desalted crude oil.
