Even when properly treated by a deaerator, boiler feedwater typically contains traces of oxygen that present a risk of corrosion to the feedwater and boiler metallurgy. Oxygen pitting attacks can result in rapid failures in feedwater lines, especially economizers, as well as boilers and condensate lines. An efficient oxygen scavenger treatment program is essential to meet industrial standards and minimize unplanned downtime, production losses and maintenance costs.
Veolia’s oxygen scavengers for boiler feedwater include several inorganic and organic oxygen scavengers that can cover all your boiler feedwater requirements.
The CorTrol IS Series of products are inorganic oxygen scavengers with a common sulfite-based chemistry. Sulfite (SO3) is the fastest oxygen scavenger, especially when combined with a catalyst. It is suitable for steam generation applications operating below 900 psig (62 barg). CorTrol IS products are available in powder and liquid forms to best suit your application’s needs.
The CorTrol OS Series of products are organic oxygen scavengers that regroup multiple chemistries such as DEHA, Carbohydrazide and others. Organic oxygen scavengers are suited for high pressure (above 900 psig/62 barg) and high purity steam generation applications that are required to limit their intake of total dissolved solids (TDS).
