  • Patent number: 9527012
    Abstract: A system operating as a centrifugal, liquid-liquid separator may be controlled, and even optimized, by automatic control of back pressure to establish an optimum position of the dispersion band therein. Optimizing to minimize impurities (from each other) in each of two separated phases is possible, even simultaneously, by reliance on a processor setting the settling lengths of both heavy and light phases at the same value. Settling length, defined in accordance with the invention, reflects a settling velocity multiplied by a residence time. Equating these lengths, for droplets of each in the other liquid, provides superior results over conventional settling theory maximizing settling area. Equalization of residence times did not provide an improvement over conventional settling theory.

  • Patent number: 7314441
    Abstract: A method for separating particulate matter from a fluid includes feeding a fluid containing a particulate matter into a chamber of a vessel through an inlet, the chamber being at least partially bounded by a peripheral wall and the chamber also communicating with a first outlet and a second outlet. The vessel is rotated such that at least a portion of the particulate matter settles out of the fluid against at least a portion of the peripheral wall. At least a portion of the particulate matter settled against the peripheral is subsequently disturbed so that at least a portion of the particulate matter is resuspend within the fluid. The method further includes removing at least a portion of the fluid having the resuspended particulate matter therein through the first outlet and removing through the second outlet the fluid from which the particulate material has settled out.

  • Patent number: 7060017
    Abstract: A separator includes a vessel having a peripheral wall bounding a chamber. The vessel is rotatable about a rotational axis extending through the vessel. The chamber communicates with an inlet and a first outlet. A tubular member is disposed within the chamber and communicates external thereof. A plurality of fins are disposed within the chamber. Each of the fins extends from toward the tubular member to toward the peripheral wall. A first tube projects from the tubular member to toward the peripheral wall. The first tube has a second outlet in communication with the chamber. The first outlet is disposed closer to the rotational axis than the second outlet such that during use a fluid boundary line first outlet and the second outlet.

  • Patent number: 6719681
    Abstract: A multiple-component fluid mixture is separated by feeding the fluid mixture into a chamber of a vessel through an inlet, the chamber being at least partially bounded by a peripheral wall and the chamber also communicating with an outlet. The fluid mixture includes a heavy component and a light component. The vessel is rotated about a rotational axis extending through the vessel such that the heavy component collects toward at least a portion of the peripheral wall of the vessel and the light component collects toward the rotational axis. The light component is removed through the outlet channel. The heavy component is removed through a conduit disposed within the chamber, the conduit extending from the heavy component toward the rotational axis and out of the vessel.
