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...


A process for the production of a gas having a substantial content of oxygen by adsorptive separation from air in an adsorption apparatus having n adsorber columns, each column containing an adsorbent material exhibiting a speed of attrition, n being no less than 3, and comprising the following sequential steps, occurring over a cycle period T for each column, with a time lag of T/n from one column to another: a) a production step in which air is fed cocurrently and production gas is withdrawn from a column, at least a portion of said production step bei...
