Abstract: A method may include: introducing a fluid comprising a first immiscible phase and a second immiscible phase into a contacting vessel comprising multiple contact stages: flowing the fluid through a first fiber bundle disposed in the contacting vessel; separating at least a portion of the first immiscible phase from the second immiscible phase; and flowing the separated portion of the first immiscible phase through a second fiber bundle disposed in the contacting vessel.

Abstract: A fiber bundle liquid-liquid contactor may comprise: a vessel comprising: a first inlet; a second inlet; a mixing zone arranged in the vessel to receive a first liquid from the first inlet and a second liquid from the second inlet, wherein the mixing zone comprises an inductor fluidically coupled to the inlet for the second liquid; and an extraction zone comprising a fiber bundle arranged in the vessel to receive the first liquid and the second liquid from the mixing zone.

Abstract: An in-line treble port venturi connector provides a low flow, low pressure inlet port for drawing supplemental fluid into a main flow path. The connector includes a main flow tube having a mixing channel restricting flow and lowering pressure between an upstream port and a downstream port. A baffle projects into the main flow tube from the inner surface of the mixing channel at a location upstream of an inlet port, obstructing main flow to create a separation zone in the low pressure area, causing rotational flow within the separation zone and lowering the average flow rate in the direction of main flow. A pressure differential allows supplemental fluid to be drawn into the mixing channel through the inlet port. The connector may be used to introduce hydrogen or oxygen gas from an on-board generator into a main flow of hydrocarbon fuel in the intake manifold of an internal combustion engine.
