  • Patent number: 10407321
    Abstract: A centrifugal, liquid-liquid separator relies on a sweep flow in excess of the flow rate naturally occurring in the heavy constituent or species being separated out from a lighter species, in order to prevent access by the long-chain polymers of the lighter species to solids that may separate out and make a durable composition of polymers and particles that adheres and compacts against the shell wall of the centrifuge.

  • Patent number: 10365270
    Abstract: A method and an ejection device are provided for discharging contaminants out of a seal chamber of a rotating-fluid machine driving a main flow of contaminated fluid. The ejection device incorporates an obstacle for arresting a portion of the flow in the seal chamber to stagnation pressure, whereby a zone of fluid at stagnation pressure is created. A discharge passage is disposed in the seal chamber adjacent to a region of concentration of contaminants and in the zone of stagnation pressure created by the obstacle, whereby contaminants are pumped out via the discharge passage into the main driven flow. The discharge passage is disposed upstream of the obstacle and provides fluid communication between the seal chamber and a process side of the machine. The method and the ejection device are operative with a machine driving fluid in clockwise direction, in counterclockwise direction, and in both clockwise and counterclockwise direction.

  • Patent number: 10350520
    Abstract: A shaker separates components of a slurry. The shaker has a screen with a pressure differential applied to the screen to remove a portion of a slurry. The pressure differential across the screen can be toggled or pulsed. Generally, various types of separators are used to separate liquids and solids. For example, oil-field drilling operations use separators with screens to remove solids from a slurry. One type of apparatus used to remove solids from drilling mud is commonly referred to in the industry as a “shale shaker.

  • Patent number: 10322417
    Abstract: Briefly, the invention provides a method for magnetically assisting demulsification of extraction phases, the method having the steps of contacting a first solution of a first solvent and a solvated paramagnetic metal ion with a second solvent, where the second solvent is immiscible with the first solvent; mixing the first and second solutions to create an emulsion having a first phase of the first solvent and second phase comprising the second solvent where the phases of the emulsion contain different concentrations of the paramagnetic metal ion; and applying a magnetic field gradient to the first and second phases of the emulsion to accelerate separation of the first phase from the second phase. Also provided is a system for demulsifying phases used in the extraction of paramagnetic moieties from solution having a lumen with an interior region, an interior surface, and exterior surface; and a magnetic field gradient present within the interior region.

  • Patent number: 10315173
    Abstract: Problem: A mixing device is provided which can solve problems resulting from friction between a vessel and a stirrer, which can generate a circulatory flow even below the stirrer, and which allows a desired number of stirrers to be arranged at desired positions. A discharge device provided with the mixing device, and a discharge method are also provided. Solution: The mixing device includes a stirrer incorporating a magnet, a stirrer holding mechanism that specifies a position of the stirrer by exerting a magnetic force on the stirrer from the lateral side, and a rotation mechanism that rotates the stirrer holding mechanism, wherein the rotation mechanism rotates the stirrer holding mechanism, thereby rotating the stirrer. The discharge device includes the mixing device, and the discharge method is carried out using the discharge device.
