The presence of oxygen and carbon dioxide gases in the water entering steam boilers can cause corrosion in this equipment. In the drilling industry, when large volumes of fluids are injected into the well in processes such as hydraulic fracturing operations, injection into saltwater disposal wells, and flooding operations, a significant amount of oxygen enters the process, which leads to several problems.
The entering oxygen causes corrosion in the well wall, drilling equipment, and pipelines. These problems are examples of the negative effects of the presence of oxygen in various industrial processes. Therefore, one of the main challenges for engineers in these industries is to remove unwanted oxygen from the processes. Oxygen scavengers are used as chemicals to react and remove oxygen in aqueous systems.
These chemicals form a layer on the metal surface, preventing dissolved oxygen from reaching the metal surface, thereby reducing the corrosion rate.
In fact, if oxygen is not removed from the environment, the oxygen in the solution reacts with iron and rapidly oxidizes it, which causes corrosion and reduces the lifespan of the equipment.

Environmental impact of Oxygen Scavenger
Oxygen absorbers can have a variety of environmental impacts, especially if they are improperly managed or disposed of. Some types of these materials contain chemical compounds such as sulfites, hydrazine, or their derivatives, which, if released into water sources, can harm water quality and affect aquatic organisms. Improper disposal of these materials can also cause soil contamination and disruption of local ecosystems. To reduce these impacts, it is essential to use biocompatible oxygen absorbers and comply with environmental regulations.
Safety Measures and Regulations for Handling Oxygen Scavenger
It is very important to follow safety principles when working with oxygen absorbers, as some of these materials may be toxic, corrosive, or irritating. Personal protective equipment such as heavy-duty gloves, safety glasses, and masks are essential to prevent contact with the skin, eyes, and respiratory tract. These materials should be stored in closed containers away from moisture, heat, and sources of ignition. Disposal of oxygen absorber waste must be carried out in accordance with environmental regulations and safety guidelines to prevent environmental pollution.
