When is industrial hydrazine/morpholine lay-up considered a loss?

When is industrial hydrazine/morpholine lay-up considered a loss?

• A. If the concentration falls below 5 ppm
• B. If the concentration falls below 10 ppm
• C. If the pressure exceeds 20 psig
• D. If the temperature drops below 60°F

Answer: (B)

Industrial hydrazine/morpholine lay-up is considered a loss when the concentration level falls below a specific threshold that indicates the effectiveness of the chemical in preventing corrosion and maintaining system integrity. The correct answer, which identifies that a loss occurs when the concentration falls below 10 ppm, highlights the appropriate minimum concentration level necessary to ensure the protective qualities of hydrazine/morpholine in preserving water systems. Maintaining the concentration above this threshold is crucial because if the levels drop below, the protective advantages against corrosion diminish significantly, potentially leading to damage or system failure. This knowledge is vital for personnel managing treatment systems in marine and industrial operations, emphasizing the importance of regular monitoring and maintenance of chemical concentrations within prescribed limits.
