Abstract: 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.

Abstract: A method of separating oxygen from nitrogen involves delivering air to a first side of a membrane comprising a polymer support and a layer of zeolite nanosheet particles with thickness of 2 nm to 10 nm and mean diameter of 5 nm to 5000 nm. The delivered air provides a pressure differential between opposite sides of the membrane, thus causing oxygen in the hollow core to diffuse through the polymer support and the zeolite nanosheet layer to the second side of the membrane. The preferential diffusion of oxygen (compared to diffusion of nitrogen) through the membrane produces nitrogen-enriched air on the first side of the membrane and oxygen-enriched air on the second side of the membrane.
