OXYTREAY 'H'

 

OXYTREAT-H is a colourless solution of hydrazine, which will effectively remove dissolved oxygen from boiler systems. The concentration is such that Oxytreat -H has no flash point.

 

PURPOSE

 

When operating modern boiler facilities even under ideal conditions, trace quantities of oxygen are left in the feed water despite mechanical de-aeration. Oxytreat- H will chemically react with active oxygen to form inactive gases of nitrogen and water. Additionally Oxytreat - H passivates metal surfaces through the formation of protective oxide films thereby minimizing iron and copper deposits in the boiler.

 

ADVANTAGES

 

1. Oxytreat -H is a liquid and easy to feed.
2. It will convert ferric oxide to a protective film of magnetic.

3. Single colourimeteric control test.
4. It doesn't contribute dissolved solids to the boiler water.

5. Reduced blowdown costs.
6. Makes iron oxide sludge non adherent by completely changing its composition.

 

FEED REQUIREMENTS

 

Feed solutions should be prepared with a minimum of stirring. Approx. 6.5 parts of Oxytreat -H are required to chemically react with one part of dissolved oxygen. When using Oxytreat -H in a system for the first time, dosage requirements will be much higher due to the consumption of Oxytreat -H by the ferric oxide present. Because of the reaction of Oxytreat -H with air, feed solutions should be made up fresh daily.

 

METHOD OF FEEDING

 

Oxytreat -H should be fed continuously for best results. A positive displacement pump should be used to feed Oxytreat -H into feed water after the deareator. Continuos feed to this area will supply continuos corrosion protection to the feed water control.

 

Oxytreat -H is controlled by checking the feed hydrazine residual in the boiler water. The recommended range is 0.1 - 0.2ppm. Control testing is a simple colourimeteric cooperator which is available from Rochem.

 

STORAGE & HANDLING

 

Oxytreat -H is harmful if swallowed. Skin contact and vapour inhalation should be avoided. Protective equipment should be worn when handling Oxytreat -H.

 

STORAGE

 

Oxytreat -H does not have a flash or fire point and does not represent a fire hazard. Direct contact and storage in high temperature areas should be avoided.

 

Keep container closed when not in use. Donot store near acids or oxidising agent.
