Abstract: Methods and systems are provided for a multiplexed phase separating inertial filter that is composed of helical through holes generating centrifugal separating forces. In one example, the inertial filter may be a planar porous material with an array of helical channels, each helical channel of the array of helical channels extending from a top surface of the porous material to a bottom surface of the porous material.

Abstract: Concentration of oxygen gas with electrochemical stacks arranged in series gas flow. A system includes a plurality of electrochemical stacks for extracting oxygen from an input gas, wherein the plurality of electrochemical stacks outputs oxygen gas and oxygen-reduced gas. The system includes a heat exchanger in fluid communication with the plurality of electrochemical stacks, wherein the heat exchanger consumes the input gas and the oxygen-reduced gas, and wherein the heat exchanger transfers heat from the oxygen-reduced gas to the input gas. The system includes a mechanical blower for driving the input gas into the heat exchanger. The system is such that the plurality of electrochemical stacks are organized in series gas flow.

Abstract: Apparatus and methods for separating a fluid are provided. The apparatus can include a separator and a collector having an internal volume defined at least in part by one or more surfaces narrowing toward a bottom portion of the volume. The separator can include an exit port oriented toward the bottom portion of the volume. The internal volume can receive a fluid expelled from the separator into a flow path in the collector and the flow path can include at least two directional transitions within the collector.
