Carbohydrazide is the proven, safer alternative to hydrazine for dissolved oxygen removal in boiler feedwater systems. In thermal power plants, hydrazine has long been the go-to oxygen scavenger, but its classification as a suspected carcinogen has driven a global shift toward safer chemistries. Carbohydrazide delivers equivalent oxygen scavenging performance with none of the carcinogen concerns.
Carbohydrazide outperforms hydrazine on a per-dose basis — field data shows that oxygen removal levels achieved with a given concentration of hydrazine can generally be accomplished with half as much carbohydrazide. It also passivates iron and copper surfaces, forming a protective magnetite layer that minimizes corrosion across mixed-metallurgy boiler systems. Its decomposition products are not a serious threat to circuit materials, and it handles more safely than hydrazine during storage and dosing.
