Abstract
<PICT:0730014/III/1> Oxygen or hydrogen is removed from an inert gas or gas mixture, e.g. nitrogen, argon, krypton, helium, neon, and xenon, by adding to the impure gas or gas mixture an amount of hydrogen or oxygen such that in the resulting gas mixture hydrogen and oxygen are present in approximately the stoichiometric proportions to form water and passing the mixture through a two stage purification system, the first stage being adapted to effect maximum possible conversion of the hydrogen and oxygen to water, and the second stage being adapted to perform the dual function of converting to water any residue of the oxygen-hydrogen mixture and of removing any oxygen or hydrogen in excess of stoichiometric proportions, the amount of hydrogen or oxygen added to the impure gas or gas mixture being automatically controlled in accordance with the content of hydrogen and oxygen in the gas leaving the first stage. Hydrogen or oxygen entering at 3 is mixed with the impure gas entering at 4 and the gas mixture passes to the first stage, where conversion to water takes place in a burner and/or in the presence of a catalyst, e.g. palladium deposited on platinum gauze. The rate of addition of hydrogen or oxygen is controlled by valve 5 operated by controller 6 coupled to a differentially coupled oxygen-hydrogen analyzer 7 in the outlet 8 from the first stage. The gases then pass to second catalyst stage, e.g. the same catalyst as first stage, followed by an absorbent capable alternatively of oxidizing to water any excess hydrogen or of combining with any excess oxygen, e.g. a mixture of copper and copper oxide. Alternatively, an absorbent capable of acting as a catalyst for the conversion may be used alone in the second stage, e.g. a mixture manganous and manganousmanganic oxides. The control may be set and re-set to give an excess of oxygen and hydrogen alternately in the gas passing to the absorbent so that the latter is automatically regenerated, and this setting of the control is conditioned by analysis at 10 of the gas passing from the second stage.
