Abstract: Disclosed is a method of improving the effectiveness of an oxygen removal unit for a fuel supply system. The method includes contacting a tube bundle with a repair liquid at 20 to 40° C. for less than two hours. The tube bundle includes tubes having an air permeable, non-porous polymer layer with discontinuities. The repair liquid includes a solvent and a curable thermoset material. The curable thermoset material is deposited in the discontinuities of the air permeable, non-porous polymer layer and cured. Also disclosed is a fuel system oxygen removal unit including a tubular bundle formed of tubes having an air permeable, non-porous polymer layer disposed on a microporous support wherein the air permeable, non-porous polymer layer includes discrete segments of a cured thermoset material.

Abstract: A method of fuel tank inerting includes separating process air into nitrogen-enriched air and oxygen-enriched air with an air separation membrane. A vacuum is applied to the air separation membrane to produce a pressure differential across the air separation membrane. The vacuum is manipulated to vary the pressure differential and vary purity of the nitrogen-enriched air.

Abstract: An electroplating system includes an enclosure with an interior, an anode lead extending through the enclosure and into the interior, and a porous body. The porous body is supported within the interior of the enclosure for coupling an electroplating solution within the interior with a workpiece. A conduit extends through the enclosure and into the interior of the enclosure to provide a flow of nitrogen enriched air to the interior of enclosure for drying and removing oxygen from the electroplating solution.

Abstract: A system is disclosed for inerting a fuel tank. The system includes a fuel tank and an air separator including a membrane with a permeability differential between oxygen and nitrogen, an air inlet and an inert gas outlet in fluid communication with a first side of the membrane, and a sweep gas inlet and an oxygen-enriched gas outlet in fluid communication with a second side of the membrane. An inert gas flow path is arranged to receive inert gas from the air separation module oxygen-depleted air outlet, and to direct inert gas to the fuel tank. A catalytic reactor is arranged to receive a fuel and air, and configured to catalytically react the fuel and oxygen in the air to form an oxygen-depleted gas, and to discharge the oxygen-depleted gas from a reactor outlet. A sweep gas flow path from the reactor outlet to the air separator sweep gas inlet.

Abstract: Provided are techniques that include operating a spiral contactor. The techniques include receiving, by a spiral contactor, a first fluid, and receiving a second fluid, wherein the first fluid is different than the second fluid. The techniques also include exchanging the first fluid and the second fluid using the spiral contactor, and outputting a deoxygenated fluid from the spiral contactor, wherein the deoxygenated fluid has a lower oxygen concentration than the first fluid.

Abstract: A system for generating inert gas includes a source of pressurized air. An air separation module including at least one permeable membrane is operable to separate the pressurized air into oxygen-enriched air and inert gas-enriched air. A fuel tank containing a fuel is arranged downstream from said air separation module. The inert gas-enriched air output from said air separation module interacts with said fuel to remove dissolved oxygen from said fuel.

Abstract: A fuel tank inerting system uses a catalytic oxidation unit to combust fuel from the fuel tank to produce inert gas, simultaneously working with a gas separator that removes dissolved carbon dioxide from the fuel before it is cycled to the thermal management system (TMS) or the engine. This prevents cavitation of carbon dioxide (gaseous bubbling) within the fuel at varying temperatures while in flight.
