Mechanism of Action: How Carbohydrazide Powder Protects Power Plant Equipment

Carbohydrazide powder, a powerful oxygen scavenger and corrosion inhibitor, plays a crucial role in protecting power plant equipment from the detrimental effects of dissolved oxygen. This section delves into the intricate mechanism of action behind carbohydrazide's effectiveness in water treatment systems.

Chemical Reactivity and Oxygen Removal

The primary function of carbohydrazide in power plant water treatment lies in its ability to rapidly react with dissolved oxygen. This organic compound, with its unique chemical structure, acts as a reducing agent, effectively converting oxygen molecules into harmless by-products. The reaction occurs swiftly, even at low temperatures, making it an ideal choice for various operational conditions within power plants.

When introduced into the water system, carbohydrazide powder dissolves readily, forming a solution that actively seeks out dissolved oxygen molecules. The compound's electron-rich nature allows it to donate electrons to oxygen, reducing it to water. This process not only removes harmful oxygen from the system but also prevents the formation of oxide layers on metal surfaces, which can lead to corrosion and equipment degradation.

Corrosion Inhibition and Metal Passivation

Beyond its oxygen scavenging capabilities, carbohydrazide exhibits remarkable corrosion inhibition properties. The compound forms a protective film on metal surfaces, creating a barrier between the metal and potentially corrosive elements in the water.
