While most standard oxygen scavengers contain ferrous carbonate and a metal halide catalyst, there are several non-ferrous variants, such as ascorbate with sodium hydrogen carbonate, among others available. [10]
It is employed in high pressure (>70 bar) boiler systems due to a very low rate of reaction at low temperatures and pressures. Due to its volatility, it acts as an oxygen scavenger throughout the entire boiler system due to steam carryover. DEHA also reacts with ferrous metals to form a passivized film of magnetite throughout the boiler system.
Oxygen scavengers or oxygen absorbers are small sachets or self adhesive labels that are placed inside modified atmosphere packs to help extend product life (notably cooked meats) and help improve product appearance. They work by absorbing any oxygen left in the pack by oxidation of the iron powder contained in the sachet/label. [1]
