Abstract: A hybrid inducer/crusher pressurizes a slurry and crushes solid fragments therein. An inner passage of uniform diameter extending through a substantially cylindrical housing comprises an inducer segment, and a crusher segment in which stationary vanes extend radially inward. A first plurality of rotating vanes extending through both segments are thinner and larger in diameter in the inducer segment than in the crusher segment. A second plurality of rotating vanes are interspersed with the first plurality in the crusher segment, thereby reducing the inter-vane spacing. In embodiments, a third plurality of rotating vanes is interspersed in the crusher segment between the first and second pluralities of vanes. The rotating vanes in the crusher segment are of equal thickness, and pass in close cooperation with the stationary vanes. The slurry is thereby pressurized in the inducer segment, and fragments are crushed in the crusher segment between the rotating and stationary vanes.

Abstract: Pressure exchange devices, systems, and related methods may include a tank, a piston, a valve device, and one or more sensors for monitoring a position of the piston in the tank.

Abstract: Devices and systems for exchanging properties between at least two fluid streams and related methods may include a valve device comprising a valve actuator configured to move at variable rates in order to selectively fill and empty at least one tank. Devices for exchanging properties between at least two fluid streams may include a valve device comprising offset openings positioned along a path of a valve actuator. The offset openings may be configured to selectively and gradually place an inlet in communication with at least one tank.

Abstract: Devices for exchanging properties, such as pressure, between at least two fluid streams and related methods may include pistons coupled to a valve stem. The valve stem and valve body may be configured to define a primary seal between the one or more pistons and the valve body and a secondary seal between the one or more pistons and the valve body.

Abstract: Devices and systems for exchanging properties between at least two fluid streams and related methods may include a valve device comprising a valve actuator configured to move at variable rates in order to selectively fill and empty at least one tank. Devices for exchanging properties between at least two fluid streams may include a valve device comprising staggered and overlapping openings positioned along a path of a valve actuator. The staggered and overlapping openings may be configured to selectively and gradually place an inlet in communication with at least one tank.
