What concentration range is typically maintained for neutralizing amines?

• A. 7.0-8.0
• B. 8.5-9.5
• C. 9.5-10.5
• D. 10.0-11.0

Answer: (B)

Neutralizing amines are typically used in steam generation systems to control pH levels and help prevent corrosion within the boiler and associated systems. The proper concentration range for these amines is generally maintained between 8.5 and 9.5. This pH range is effective because it helps ensure that the amines adequately neutralize any acidity present in the water, which can occur due to dissolved gases like carbon dioxide and oxygen. Maintaining a pH in this range is crucial as it optimizes the performance of the amines while preventing the formation of corrosion-causing conditions. If the pH is too low, it may not provide sufficient neutralization, leading to increased corrosion rates. Conversely, if the pH is too high, it can lead to other issues, such as the formation of scale. The concentration range of 8.5 to 9.5 strikes a balance that protects the integrity of the system while allowing for efficient operation, making it the correct choice for maintaining the effectiveness of neutralizing amines in water treatment systems.
