CorTrol* OS5601
oxygen scavenger
- Controls oxygen corrosion
- Passivates pre-boiler and boiler surfaces
- Improves boiler reliability
- Acceptable for high-purity nuclear and once-through applications
description and use
CorTrol OS5601 is an oxygen scavenger designed to control corrosion caused by dissolved oxygen in pre-boiler and boiler systems.
The scavenger in CorTrol OS5601 does not contribute inorganic solids to the treated water. The treated water may be used for steam attemperation and to lay up non-drainable superheaters.
CorTrol OS5601 is formulated to meet or exceed the most demanding product purity requirements. It is the product of choice for nuclear applications and in all volatile systems where even minor product impurities are a concern.
The scavenger in CorTrol OS5601 is of low toxicity, but it is not suitable for systems where additives to the steam are regulated by the FDA or the USDA.
This product may not be used in drinking water systems or where steam is used for humidification.
typical applications
Even with good deaerating heater operation, sufficient dissolved oxygen can remain in the feedwater to damage the boiler system. Oxygen in water produces pitting, which is severe because of its localized nature. Economizers and feedwater preheaters are highly susceptible to oxygen attack.
Water Technologies & Solutions fact sheet
The reaction products of CorTrol OS5601 with oxygen are water, nitrogen and carbon dioxide. Oxygen scavenging with this product contributes no dissolved solids to the treated water.
treatment and feeding requirements
Feed Point – Feed CorTrol OS5601 to the condensate hot well, the deaerator storage section or the feedwater line.
Feedrate – Feed CorTrol OS5601 continuously based on the feedwater dissolved oxygen concentration and the presence of a suitable residual.
Dilution – CorTrol OS5601 should be fed neat to a point in the system where good distribution and mixing will occur.
Equipment – Because of the low toxicity (see Material Safety Data Sheet [MSDS]) of CorTrol OS5601 compared to hydrazine, it does not require a system designed to minimize operator exposure.
