초록

In a unit for the production of oxygen by separation of air by adsorption with regeneration of the adsorbers (1-5) under vacuum, the sub-atmospheric depressurization is ensured with rejection to the atmosphere by pumping with two successive pumping devices: one, for example of the type of a volumetric compressor (13), operates to a pressure of the order of 0.5×105 Pa absolute, while the other, for example of the type of a centrifugal compressor (14), operates alone to a pressure of the order of 0.2×105 Pa absolute.

In a process for the production of a gas with a substantial oxygen content by adsorption of nitrogen from air, with a plurality “n”of adsorbers, wherein there is successively and cyclically assured according to a period T, in each of said adsorbers, with a time offset of T/n, from one adsorber to the next: a) a production stage of said gas with a substantial content of oxygen by withdrawal of gas in a direction called co-current at high pressure, with admission of air; b) a depressurization stage incorporating a counter-current terminal pumping phase und...
