A method and system for providing nitrogen-enriched air (NEA) to aircraft fuel tanks using multiple air separation modules (ASMs). The ASMs employ membranes having different permeabilities and selectivities which are particularly selected to meet the varying NEA needs of the fuel tanks during flight.


1. A method for inserting an aircraft fuel tank, said method comprising the steps of: (a) contacting compressed air with one or more first membrane modules at conditions effective to produce a first nitrogen-enriched air stream;(b) introducing said first nitrogen-enriched air stream into said fuel tank during periods of low demand for nitrogen-enriched air;(c) contacting compressed air with one or more second membrane modules at conditions effective to produce a second nitrogen-enriched air stream; and(d) introducing said second nitrogen-enriched air str...
