ABSTRACT:
The formation of amine or glycol degradation products in solutions used to remove acid gases or water from hydrocarbon or inert streams is reduced by adding to the solution an oxygen scavenger in which the effective component is an oxime of the formula: ##STR1## Mixed with a quinone promotor in which R.sub.1 and R.sub.2 are the same or different and are selected from hydrogen or lower alkyl groups of one to six carbon atoms. The addition of the quinone promotor increases the reactivity with oxygen at lower temperatures. The compound may also be as a corrosion inhibitor in gas treating or processing equipment.
