<p>Method for producing oxygen (1) from air (2), in which, for this purpose, a generator (3) is used that generates oxygen at its outlet (4), from air introduced at its inlet (5). According to the invention, the generator operating continuously, use is made of: - at least two buffer tanks (6, 7) for storing the oxygen generated by the generator, which are placed in parallel, - and a control system (8) for at least adjusting the flow rate and/or pressure of the oxygen produced, to the demand in flow rate (9) and/or pressure (10) of the application. The control system (8) comprises at least one module (81) for controlling the two buffer tanks (6, 7), performing the following functions: (a) the storage in one (6) of the buffer tanks, called nominal tank, of a nominal oxygen reserve for maintaining an oxygen outlet pressure, called nominal pressure, and/or an outlet flow rate, called nominal flow rate, (b) the storage in the other (7) buffer tank, called peak tank, of an oxygen peak reserve, for maintaining an oxygen pressure called peak measure, which is higher than or equal to the pressure called nominal pressure, and/or an outlet flow rate, called peak flow rate, which is higher than or equal to the nominal flow rate, (c) according to the oxygen pressure (10) demanded, an offtake at the outlet of the nominal tank (6) and/or the peak tank (7), (d) the control (82) of the generator (3) for generating and resupplying oxygen continuously to the nominal tank (6) and/or the peak tank (7).</p> |
