초록

In the process for the production of oxygen by adsorption, the following combination of steps are used: the number of adsorbers is at least three; the time of pumping y under sub-atmospheric pressure during step b) is higher than dephasing T/n, and at least equal to the time x of the production step; the phase of pumping of the column of adsorbent material is carried out by using on said adsorption column successively at least two systems of pumping wherein one is in operation from the start of the pumping operation, another one is adapted to operate unt...
