Oxygen Scavengers
Oxygen Scavengers are chemical compounds used to remove or reduce oxygen levels in various systems, such as packaging, water treatment, or industrial processes. They play a critical role in preventing oxidation, corrosion, and microbial growth in environments where oxygen presence can be detrimental.
The components of an oxygen absorber vary according to intended use, the water activity of the product being preserved, and other factors. 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.
Chemway is one of the OxygenScavangers, manufacturers, exporters, and suppliers in Fujairah, Sharjah, Abu Dhabi, Ajman, Ras Al Khaimah, Kuwait, Muscat, Dubai UAE.

Product Details
- Food and Beverage Industry:
- Packaging: Oxygen scavengers are commonly used in food packaging to extend shelf life and preserve freshness. Packets containing scavengers are placed inside sealed packages of perishable goods like snacks, coffee, dried foods, and meats. They prevent the oxidation that causes spoilage, discoloration, flavor degradation, and rancidity.
- Beverages: Oxygen can affect the taste and quality of beverages, especially those like beer, wine, and fruit juices. Oxygen scavengers in caps or lining materials help maintain the freshness and flavor by eliminating dissolved oxygen.
- Water Treatment Industry:
- Boiler and Steam Systems: Oxygen scavengers are vital in treating feedwater for boilers and steam systems. Dissolved oxygen in water can cause pitting and corrosion of metal surfaces. Oxygen scavengers like sodium sulfite, hydrazine, or DEHA are added to boiler feedwater to remove oxygen, prolonging the life of the boiler and reducing maintenance costs.
- Cooling Towers and Closed Water Systems: In cooling systems, oxygen scavengers are used to prevent corrosion in piping, radiators, and other system components, ensuring long-term efficiency and preventing costly breakdowns.
- Oil and Gas Industry:
- Corrosion Prevention in Pipelines: Oxygen scavengers play a crucial role in the oil and gas industry, particularly in preventing corrosion in pipelines that transport oil, gas, or water. Oxygen in pipelines can cause rust and damage, leading to leaks and expensive repairs. Oxygen scavengers, typically injected into the system, help mitigate this risk by reacting with and eliminating oxygen.
- Enhanced Oil Recovery (EOR): In the EOR process, oxygen scavengers help maintain the integrity of pipelines and storage tanks by controlling oxygen levels in the water injected into oil wells.
- Pharmaceutical and Chemical Industry:
- Product Protection: Oxygen scavengers are used to protect sensitive pharmaceuticals and chemicals from degradation due to oxidation. Many drugs, active pharmaceutical ingredients (APIs), and chemical formulations are highly sensitive to oxygen, which can reduce their potency, alter their composition, or change their appearance.
- Packaging: In the packaging of pharmaceuticals, oxygen scavengers are added to prevent oxidation that could reduce the efficacy of oxygen-sensitive medications or chemicals, ensuring they remain stable and effective for longer periods.
- Power Generation Industry:
- Boiler Water Treatment: Power plants, especially those relying on steam turbines, use oxygen scavengers to treat the water in their systems. The presence of oxygen in steam and water can cause significant corrosion, leading to downtime and costly repairs. Oxygen scavengers such as hydrazine or sulfites are used to remove dissolved oxygen and protect the equipment.
- Cooling Systems: Similar to boiler systems, oxygen scavengers are used to protect cooling water circuits and maintain the efficiency of heat exchangers and other critical components.
- Aerospace and Electronics Industry:
- Electronic Component Preservation: In the electronics industry, oxygen scavengers are used in the packaging of sensitive components to prevent oxidation, which can lead to degradation of performance or malfunction. This is particularly important for high-precision electronic parts that need to remain stable over long periods.
- Aerospace Applications: Oxygen scavengers help preserve highly sensitive materials and components used in aerospace systems that can be affected by oxygen exposure during long-term storage or operation.
- Automotive Industry:
- Fuel Systems: In automotive fuel systems, oxygen scavengers are used in fuel additives to prevent oxidation, which can lead to the formation of gum and varnish in fuel injectors and other components.
- Coolant Systems: Oxygen scavengers help protect the metal components of engines and radiators by preventing oxidation and corrosion in automotive cooling systems.
- Pulp and Paper Industry:
- Boiler Water Treatment: The pulp and paper industry relies on large boilers for processing. Oxygen scavengers are used in the treatment of boiler feedwater to prevent oxygen-induced corrosion, ensuring that equipment operates efficiently and lasts longer.
- Bleaching Processes: Oxygen scavengers are sometimes added during the paper bleaching process to control unwanted oxidation reactions that can affect the quality of the paper.
- Marine Industry:
- Ship Boilers and Engines: Oxygen scavengers are used in marine vessel boilers and cooling systems to remove dissolved oxygen from water. This prevents corrosion of ship boilers, condensers, and pipelines, which are crucial for the operational efficiency and safety of marine vessels.
- Storage Tanks: In ships that carry fuel or chemicals, oxygen scavengers are added to storage tanks to prevent oxidation of the cargo, ensuring the quality of the stored material and protecting the tank from corrosion.
- Medical Devices and Healthcare Industry:
- Sterile Packaging: Medical devices that are sensitive to oxygen, such as certain bandages, syringes, and implantable devices, use oxygen scavengers in their packaging to maintain sterility and prolong the shelf life of the products.
- Pharmaceutical Packaging: Oxygen scavengers help protect oxygen-sensitive drugs, ensuring that medicines retain their potency and are safe for use.
- Renewable Energy Sector:
- Biogas Production: Oxygen scavengers are used in biogas production to protect equipment from corrosion and ensure the efficient operation of anaerobic digesters by maintaining low oxygen levels.
- Hydrogen Production: In hydrogen generation, where purity is critical, oxygen scavengers are used to remove trace amounts of oxygen, ensuring the production of high-quality hydrogen.
- Metal Processing and Manufacturing:
- Metal Preservation: Oxygen scavengers are used in metal processing to prevent oxidation during the heat treatment of metals or in processes like welding and brazing. They help maintain the metal’s surface quality and prevent rusting.
- Storage of Metal Components: Oxygen scavengers are employed in the storage of metal parts and machinery to prevent oxidation and corrosion during long-term storage or shipping.
- Cosmetics and Personal Care Industry:
- Preservation of Products: Oxygen scavengers are used in cosmetic products to prevent oxidation of oils, fragrances, and other active ingredients. This helps maintain product stability and shelf life.
- Packaging: In sealed containers of creams, lotions, or serums, oxygen scavengers are used to ensure that oxygen does not degrade the product’s quality.
