Abstract
An adiabatic pressure swing absorption process is disclosed for the removal of essentially all oxygen contained in an inert gas stream in minor amounts. The oxygen is absorbed and desorbed adiabatically from a dioxygen sorbent. Optionally, an inert purge gas can be utilized to improve the desorption of oxygen from the dioxygen sorbent. The process utilizes at least two switching beds of the dioxygen sorbent in which one bed is in an absorbing mode while the other bed is in a desorbing mode.
