AU-37 Oxygen Scavenger
AU-37 Oxygen scavenger
Industrial water containing dissolved gases can cause a variety of corrosion problems.
In particular, the oxygen dissolved in water is highly corrosive, even in the case of
very low concentrations, can also cause serious problems. Dissolved oxygen caused by
corrosion of the equipment, will shorten the life of the equipment, resulting in economic
losses, and prone to accidents, threats to production safety.
Dissolved oxygen in water is mainly caused by corrosion or pitting of metal corrosion
pits. Because the corrosion is concentrated, it is particularly serious. Therefore, in addition
to oxygen from the water issue has long attracted people's attention and attention, made a
number of ways and means to remove dissolved oxygen. Now frequently used methods
include mechanical oxygen, heat and chemical oxygen oxygen. Chemical oxygen method
in the boiler water system is an auxiliary method in the use of other methods such as
thermal stability of oxygen to the control center of dissolved oxygen in the water after the
re-use center of chemical oxygen scavenger residual oxygen and water to remove the
chemical reaction . Oil drilling mud. Dissolved oxygen is injected into the center to take
water directly to the mud or water Tijia the right amount of oxygen to be removed.
Chemical oxygen scavenger are commonly used inorganic sulfite, which can restore the water
of oxygen, but the reaction is slow, the need to add more divalent or divalent metal ions
as a catalyst to accelerate the speed of response, while produce such drugs because SO42 -
easy to produce corrosion and scaling new now use an oxygen scavenger, hydrazine hydrate
more quickly react with oxygen in the water, surface water and with given equipment and
pipeline corrosion products of reaction, can prevent corrosion of equipment in addition
to, However, hydrazine hydrate is a virulent, volatile explosive, which limits the application
of recent years, our research and development through unremitting efforts of the new alternative
to hydrazine oxygen scavenger, it has both good properties of oxygen, both non-toxic, and easy
to use, and the price is not high, multi-functional oxygen scavenger.
