Abstract

The method serves for operating an air fractionization installation for obtaining oxygen on board an aircraft, with at least two molecular sieve chambers. A part mass flow of the oxygen obtained in the respective adsorbing molecular sieve chamber is supplied for flushing a desorbing molecular sieve chamber. The quantity of the flushing oxygen led to the desorbing molecular sieve chamber is controlled by way of this.
