Often the oxygen absorber or scavenger is enclosed in a porous sachet or packet but it can also be part of packaging films and structures. [4] Others are part of a polymer structure. [5] Oxygen absorbing chemicals are also commonly added to boiler feedwater used in boiler systems, to reduce corrosion of components within the system. [6]
Location of Singapore Singapore is a sovereign island country in maritime Southeast Asia. A global city, it has a highly developed market economy, based historically on extended entrepôt trade and more recently as a financial hub as well. Its economy is known as the most freest, most innovative, most competitive, most dynamic and most business-friendly in the world by various multinational ...
It is a volatile oxygen scavenger [2] [3] and reacts in a ratio of 2.8/1 DEHA/O2. 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.
Most lower pressure systems (lower than 650 psi (4,500 kPa)) use non-volatile treatment programs. The most commonly used oxygen scavenger for lower pressure systems is sodium sulfite (Na 2 SO 3). It is very effective and rapidly reacts with traces of oxygen to form sodium sulfate (Na 2 SO 4) which is non-scaling. Most higher pressure systems ...

Therefore, the reduction of oxygen and its replacement with other gases can reduce or delay oxidation reactions and microbiological spoilage. Oxygen scavengers may also be used to reduce browning due to lipid oxidation by halting the auto-oxidative chemical process. Besides, MAP changes the gaseous atmosphere by incorporating different ...
