Oxygen scavenging with enzymes
An effective method of reducing the amount of oxygen present in an aqueous fluid is described, which protects materials otherwise susceptible to oxidative degradation in the presence of free (dissolved) oxygen. The method comprises reacting the oxygen with an alcohol selected from the group consisting of methanol, ethanol, propanol, and butanol, in the further presence of alcohol oxidase. An oxygen containing aqueous fluid is a fluid comprising water and free oxygen. The fluid containing free oxygen can be, for example, oil field fluids, recycle water, foodstuffs, etc. The method is applicable to oil field aqueous fluid systems in order to protect oil field equipment to avoid molecular degradation of polymeric viscosifiers used in floods, etc., and to treat foodstuffs. 17 claims.
