  • Patent number: 10307694
    Abstract: A phase splitter for separating a multiphase fluid into a relatively light phase and a relatively heavy phase includes a separator tube which comprises a fluid inlet through which the multiphase fluid enters the apparatus, a heavy phase outlet through which the heavy phase exits the apparatus and an inner diameter surface which defines a flow bore that extends between the fluid inlet and the heavy phase outlet. A swirl element positioned in the flow bore downstream of the fluid inlet causes the multiphase fluid to rotate and separate the heavy phase from the light phase. The light phase forms an elongated core which extends axially through the flow bore radially inwardly of the heavy phase from proximate the swirl element toward the heavy phase outlet. A core stabilizer is positioned in the flow bore between the swirl element and the heavy phase outlet and engages the distal end of the light phase core to thereby inhibit the light phase from exiting the apparatus through the heavy phase outlet.

  • Patent number: 10265645
    Abstract: Provided is a method for producing an electrode paste capable of readily and reliably removing bubbles from the produced electrode paste. A method includes a step for performing vacuum-defoaming of bubbles present in an electrode paste (8) by vacuuming the inside of a defoaming tank (6) while introducing the electrode paste (8) to the defoaming tank (6). In the step for performing vacuum-defoaming of bubbles present in an electrode paste (8), a rising velocity (fluid surface rising velocity VL) of the fluid surface of the electrode paste (8) in the defoaming tank (6) is made smaller than a rising velocity (reference bubble rising velocity VGa) of the bubbles in the electrode paste (8) by adjusting a flow rate (supply flow rate Q) of the electrode paste (8) introduced to the defoaming tank (6).
