Effects of Working Temperature and Working Pressure on Separation Coefficient and Pressure Drop of Hollow Fiber Membrane Module in an Aircraft Fuel Inerting System

Abstract:

Air separation experiments were conducted in a hollow fiber membrane module under various working conditions. Effects of working temperature and working pressure on separation coefficient and pressure drop were investigated when the mass fraction of oxygen in the nitrogen-rich gas was 2%, 5% and 12%, respectively. It is revealed that high temperature working and storage (100°C) of the hollow fiber membrane module could help to obtain higher separation coefficients for the 2% and 5% oxygen concentrations and when the oxygen concentration of the nitrogen-rich gas was 12%, the result was opposite. For the pressure drop, the low temperature working and storage (-55°C) working conditions led to lower values. Furthermore, low working pressure (an 11 km height pressure) is helpful to gain higher separation coefficient and not favorable to obtain lower pressure drop.
