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： 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.
