Carbohydrazide (CH) is a chemical compound commonly used as an oxygen scavenger in boiler water treatment. It belongs to the class of compounds known as carbamidines and is specifically designed to react with dissolved oxygen in boiler water, thereby removing it.
Here are some key aspects of carbohydrazide as an oxygen scavenger in boiler water treatment:
Oxygen Removal: Carbohydrazide reacts quickly with dissolved oxygen in boiler water, converting it into inert nitrogen-based compounds. This reaction effectively removes oxygen, which can otherwise cause corrosion and scaling issues in boilers.
Corrosion Prevention: By removing oxygen from the boiler water, carbohydrazide helps prevent oxygen-induced corrosion of boiler metals. Corrosion can lead to premature failure of boiler components, affecting their efficiency and lifespan.
Compatibility with Other Chemicals: Carbohydrazide is generally compatible with other boiler water treatment chemicals, such as scale inhibitors and pH adjusters. It can be used in conjunction with these chemicals to ensure comprehensive boiler water treatment.
Dosage and Monitoring: The dosage of carbohydrazide required depends on the concentration of dissolved oxygen in the boiler water. Regular monitoring of the oxygen level is essential to adjust the dosage accordingly. Excessive dosing can lead to unnecessary chemical consumption, while insufficient dosing may not effectively remove oxygen.
Safety Precautions: When handling carbohydrazide, it is important to follow safety precautions, including wearing protective equipment, storing the chemical in a well-ventilated area, and avoiding contact with skin or eyes. Additionally, disposing of used carbohydrazide should be done according to local regulations.
Environmental Considerations: While carbohydrazide is effective in removing oxygen from boiler water, it can form nitrogenous compounds during the treatment process. These compounds may have environmental impacts, especially if released into surface waters. Therefore, it is important to follow recommended best practices for the disposal of treated boiler water.
