A method and apparatus of augmenting the coalescence of water in a water-in-oil emulsion in which the emulsion is tangentially ejected into the interior of a cylindrically walled vessel to cause the emulsion to flow circumferentially within the vessel and to thereby cause the water component of the emulsions to migrate towards the vessel cylindrical wall, the vessel having an axially positioned electrode therein. A voltage, preferably a pulsating DC voltage, is imposed between the electrode and the vessel to thereby subject the swirling water-in-oil emulsion to an electrical potential to cause the water components to coalescence from smaller to larger droplets. The water-in-oil emulsion is passed from the vessel where the water component can be more effectively separated from the emulsion by gravitational or centrifugal separation. |

The invention provides a method of separating the components of a liquid/liquid dispersion or emulsion, comprising the step of applying simultaneously to the dispersion or emulsion both an electric field and an aligned centrifugal force, in such a way as to set up a bulk interface at right angles to the direction of the electric field and centrifugal force, the bulk interface being located within the electric field between the dispersion or emulsion and one separated component thereof. The combined effects of the electric field and centrifugal force break the liquid emulsion, preventing the formation of a sponge layer at the interface and hence allowing more effective separation of the components than has previously been possible. The invention also provides apparatus for carrying out the claimed method of separation. |

The present invention is conceived to provide methods for efficiently separating two liquids different in sp. gr. which are in a mixed state and apparatuses for implementing them.The present invention devised an arrangement such that between an outer cylindrical electrode doubled as an apparatus container and an inner cylindrical electrode concentrically disposed relative to said outer cylindrical electrode and set to the equal potential to that of the outer cylindrical electrode, a charging electrode is provided concentrically thereto, thereby defining not only between the aforementioned electrodes mixture liquid passage spaces for letting the mixture of two liquids flow upwardly, but a separated liquid collecting space above said mixture liquid passage spaces, and that inside the inner cylindrical electrode, there is provided a space for letting the liquid to be separated flow down which is designed to guide downwardly the liquid to be separated left after removal of the impurity liquid, with a voltage high enough to neutralize the zeta potential of impurity liquid particles in the mixture applied between the aforementioned electrodes, respectively. In this way, not only the impurity liquid particles in the mixture are got cohere together into coarse particles by dint of their intermolecular attraction, but the separated liquid which has floated up or settled down, according to the sp. gr. difference between the mixture and the coarse particles, is collected and, then, discharged. |

Electrodes, in the form of plates, are held parallel to each other to form passageways in which electrostatic fields are generated when the plates are charged by a source of variable voltage. The variable voltage is programmed to establish an initial electrostatic field strong enough to mix polar and nonpolar fluids. The mixture is then flowed through the electrostatic field which is of the strength needed to coalesce the polar fluids which have united with a contaminant in the nonpolar fluid. |

Improved electrodes for electrically coalescing water-in-oil emulsions in an AC electrical field, wherein the improvement comprises insulated electrodes having a dielectric constant of at least about 3 and a hydrophobic surface in contact with the emulsion. This invention results in faster coalescense of emulsions than can be obtained with insulated electrodes having a lower dielectric constant even if the surface of the electrode at the electrode-emulsion interface is hydrophobic. Formation of spongy emulsion and decomposition of the oil phase under the high voltages required for rapid coalescense is minimized and even eliminated. |

An improved electrostatic coalescence system is provided in which independent AC and DC hydrophilic electrodes are employed to provide more complete dehydration of an oil emulsion. The AC field is produced between an AC electrode array and the water-oil interface wherein the AC electrode array is positioned parallel to the interface which acts as a grounded electrode. The emulsion is introduced into the AC field in an evenly distributed manner at the interface. The AC field promotes drop-drop and drop-interface coalescence of the water phase in the entering emulsion. The continuous oil phase passes upward through the perforated AC electrode array and enters a strong DC field produced between closely spaced DC electrodes in which small dispersed droplets of water entrained in the continuous phase are removed primarily by collection at hydrophilic DC electrodes. Large droplets of water collected by the electrodes migrate downward through the AC electrode array to the interface. All phase separation mechanisms are utilized to accomplish more complete phase separation. |

An electrode is fluid-coupled to the driven electrode, which is directly connected to either an AC or a DC source of potential. The driven electrode is provided with the usual ground electrode to establish the electrostatic field of a coalescing system. The electrode fluid-coupled to the driven electrode is positioned to establish two zones in the electrostatic field. A fluid mixture is passed through the two zones of the electrostatic field, in sequence. The intensity of the field in the first zone decreases as the dispersed polar fluid of the mixture increases, in relation to the less polar fluids of the mixture. At the same time, the field in the second zone increases in intensity. The field gradient shifts between the two zones, in accordance with the quantity of the polar fluid in the mixture passed through the zones in the field, in sequence. |

Fluids are separated from each other by passing their mixture through an electric field and centrifuge in sequence. The drops of a first fluid dispersed in a second fluid are coalesced by the force of an electric field to a predetermined size. The mixture is then passed into a centrifuge which develops the force to move the coalesced drops away from the other fluids of the mixture without reaching the value at which fluid shear forces, between the coalesced fluid and the fluid in which the coalesced fluid is dispersed, will fragment the coalesced drops. |
