N2 continuous operation range is

N2 continuous operation range is

• A. 95-101%
• B. 101-103%
• C. 60-100.1%
• D. 103% max

Answer: (B)

A continuous operation range is the span of operating conditions where the system can run steadily and stay within design limits under normal use. For N2, the setup expects the process to sit just above the nominal value, giving a small buffer to account for instrument bias and losses, but not so high that safety limits or control systems saturate. That’s why the correct description is a narrow band that starts just over the nominal value and extends a little higher. The other options imply operating below the nominal, or only giving an upper limit, which isn’t the intended continuous operating window.
