Abstract: Non-hydrated iron oxides utilized in moistened permeable beds to react hydrogen sulfide present in natural gas do not totally lose their reactivity when the beds give up their moisture to dry gas. Lessening of their reactivity attendant to dryness is signalled by a rise in H.sub.2 S level in the gas at or somewhat in advance of the reactor outlet. On such signal water is injected into the inflowing gas stream, reviving the bed's reactivity and permitting continuation of gas sweetening until the reactive potential of the oxide is substantially fully utilized, with minimal water addition.

Abstract: A composition suitable for scavenging oxygen from aqueous systems, for example those used in well drilling, is provided which comprises a mixture of an oxygen-reactive sulfite and/or bisulfite (sulfite component) and an amount of iron oxide particles sufficient to catalyze the reaction between oxygen and the sulfite component. These particles have certain properties as further described herein. These compositions also serve as corrosion inhibitors in aqueous systems, such as drilling muds, to protect steel components from corrosion. A method is also provided for using such compositions in aqueous systems to scavenge oxygen from such systems, and also H.sub.2 S, if present.
