  • Patent number: 11873454
    Abstract: An elongate, horizontally level, pipe includes a circumferential wall. The pipe flows, within the circumferential wall, process fluid that includes a first fluid and a second fluid immiscible with the first fluid. The first fluid and the second fluid are separated by an interfacial layer. Heating coils are disposed within the pipe. Each heating coil passes through an interior region of the pipe between the circumferential wall at a respective height from a bottom of the pipe. The heating coils generate heat. A controller is connected to the heating coils. The controller triggers at least one of the heating coils that is nearest to a location of the interfacial layer within the interior region to apply heat to the interfacial layer. The heat is sufficient to at least partially demulsify the interfacial layer.

  • Patent number: 8221596
    Abstract: Disclosed is a system and method for generating time variant and invariant electric fields (E-fields) for various applications. Generating the E-field utilizes high impedance dielectric materials having a collection of three imperative material properties: high permittivity (?), high volume resistivity (?) and high maximum allowable E-field stress (?) and physical geometries that take advantage of the manner in which E-fields are divided or distributed in series capacitance networks. The generated E-field can act upon a subject material, including a gas, liquid or solid, wherein the material is stationary or in motion. The method allows an E-field of given intensity to be set up in the subject material with a significantly lower applied voltage ?a, or conversely, a significantly higher E-field intensity with a given applied voltage ?a.
