摘要: A fuel tank inerting system includes a primary catalytic reactor comprising an inlet, an outlet, a reactive flow path between the inlet and the outlet, and a catalyst on the reactive flow path. The catalytic reactor is arranged to receive fuel from the fuel tank and air from an air source that are mixed to form a combined flow, and to react the combined flow along the reactive flow path to generate an inert gas. The system also includes an input sensor that measures a property of the combined flow before it enters the primary catalytic reactor and an output sensor that measures the property of the combined flow after it exits the primary catalytic reactor.

摘要: A nitrogen generation system includes a heat exchanger for receiving supply air and cooling air and providing temperature conditioned supply air, a flow control valve for controlling a flow of the cooling air through the heat exchanger, and an air separation module for receiving the temperature conditioned supply air and generating nitrogen-enriched air. The nitrogen generation system also includes a sensor for measuring a parameter of the nitrogen-enriched air selected from the group consisting of a temperature, a flow rate, an oxygen concentration, and combinations thereof, and a controller connected to the sensor and the flow control valve for controlling the flow of the cooling air through the heat exchanger based on the parameter of the nitrogen-enriched air measured by the sensor.

摘要: An inerting system includes a fluid circuit, a reactor within the fluid circuit, at least one particulate removal device (PRD) downstream from the reactor, and a fluid tank. The fluid tank is downstream from the at least one PRD. A method for removing particulates from a fluid stream in a fluid circuit includes receiving a fluid stream in a reactor within a fluid circuit, outputting an exhaust stream from the reactor, receiving the exhaust stream in at least one PRD downstream from the reactor, removing particulate from the exhaust stream, and receiving the exhaust stream with particulate removed in a fluid tank downstream from the at least one PRD.

摘要: A system is disclosed for inerting a fuel tank. The system includes a fuel tank and an air separator including an air inlet, a membrane with a permeability differential between oxygen and nitrogen, an oxygen-depleted air outlet, and an oxygen-enriched air outlet. A catalytic reactor is arranged to receive oxygen-depleted air from the oxygen-depleted air outlet and fuel, to react the fuel with oxygen in the oxygen-depleted air, and to discharge an inert gas from a reactor outlet. An inert gas flow path is arranged to receive inert gas from the reactor outlet, or from the air separation module oxygen-depleted air outlet, or from the reactor outlet and from the air separation module oxygen-depleted air outlet, and to direct inert gas to the fuel tank.

摘要: A method is disclosed for removing ozone from a gas. According to this method, the gas is contacted with an adsorbent that includes a transition metal oxide or metal organic framework to form a treated gas. The treated gas is contacted with a noble metal catalyst to catalytically decompose ozone in the treated gas, thereby forming an ozone-depleted treated gas.
