Abstract: L'invention concerne un séparateur rotodynamique (30) pour séparer un liquide et un gaz d'un fluide multiphasique, notamment pour une utilisation dans le domaine pétrolier. Ce séparateur comporte un cylindre (12) libre en rotation autour de l'axe (xx), une entrée sensiblement axiale (1) du fluide multiphasique, une sortie (5) de liquide et une sortie (6) de gaz. Au moins un aubage (15) disposé le long de l'axe (xx), dans le sens de circulation (F) dudit fluide multiphasique est mis en place et est solidaire du cylindre (12). Les aubages (15) sont dirigées vers l'axe (xx) du cylindre (12). De plus, le diamètre intérieur des aubages (15) diminue progressivement, dans la partie du séparateur située en amont de la sortie de la deuxième phase, dans le sens de circulation du fluide multiphasique, tout en restant supérieur au diamètre interne de la sortie (6) de gaz.

Abstract: A centrifuge rotor (110) includes a rotor body (116) having a base (123), a sidewall (127), and a top (129). The top (129) defines an opening (131 that provides access to an annulus cavity (122) inside the rotor body (116). A cover (118) is removably attachable to the rotor body to seal the annulus cavity. A drive hub (124) extends from a portion of the base of the rotor body and couples to a drive shaft of a centrifuge motor. The rotor body (116) is sized to receive one or more sample containers (202) in the annulus cavity (122), and to constrain the one or more sample containers inside the annulus cavity between the base, the sidewall, and the top when the one or more containers are advanced radially against the sidewall.

Abstract: A dynamic energy harvesting and variable harvesting force system is disclosed. A boost converter increases a motor voltage as a motor current associated with the motor voltage propagates through the boost converter thereby generating a boost voltage associated with the changing motor current. A power storage device stores energy harvested by the boost converter when the boost voltage exceeds an energy storage threshold. A controller dynamically adjusts a harvesting force applied by the motor so that the harvesting force is relative to the force applied to the motor. The controller also dynamically adjusts the harvested energy stored by the power storage device by adjusting the charging of the power storage device, ensuring that the boost voltage threshold is maintained. The boost voltage when maintained within the boost voltage threshold enables the power storage device to store the harvested energy without impacting the harvesting force applied by the motor.

Abstract: Embodiments provide a fluid recovery system and method for use with concentrator systems for concentrating particles suspended in a fluid and where this suspension is recovered from a fluid stream drawn from the concentrator system. A controller is configured to control valve actuation to direct concentrate being drawn from the concentrator chamber through a recovery tube to a recovery reservoir based on fluid volume movement. The system can use a density sensor to detect density transitions in fluid in the fluid recovery tube to identify leading and trailing edges of a portion of concentrated particles in fluid suspension passing through the recovery tube and actuate recovery valves based on objectives for maximising particle recovery with minimal dilution.

Abstract: A separator (101) for separating raw milk (RM) into a skimmed milk phase (SM), a cream phase (CR) and an ejection phase (SI) that comprises solid impurities is disclosed. The separator comprises an ejection port (104) arranged at a periphery (105) of the separator to eject the ejection phase. A cyclone (109) is connected to the ejection port to receive and decelerate the ejection phase, and a vessel (107) in fluid communication with an ejection (112) phase outlet of the cyclone (106) to receive and collect the ejection phase from the cyclone. The cyclone comprises a port (108) that is open to the atmosphere, such that pressure build-up created in the cyclone when the ejection phase is ejected from the separator into the cyclone is released.
