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.

Adiabatic pressure swing absorption process for removing low

An adiabatic-isothermal swing absorption process is disclosed for the removal of essentially all oxygen contained in an inert gas stream. The oxygen is absorbed from an inert gas stream adiabatically on to a dioxygen absorbent and then desorbed from the absorbent isothermally by the use of external heat. The process method utilizes at least two switching beds of the dioxygen absorbent in which one bed is in an absorbing mode while the other bed is in a desorbing mode.

Process for removing oxygen from mixed gas streams using a swing

This invention relates to an improved adiabatic process for separating hydrogen from mixed gas streams using hydridable materials as the absorbing medium. The improvement comprises utilizing a composite comprising a thermal ballast in admixture with the hydride material to absorb the heat of reaction and to aid in desorption. By virtue of the intimate contact of the ballast with the hydridable material rapid cycle times plus good bed utilization are achieved.
