In the Aspen sensitivity analysis, the operating variable needs to be set as the oxygen concentration in the air
Thread Content
How do I set the operating variable to oxygen concentration? I need help from experts~~~ I can only find an option to increase the oxygen flow rate in the air, but increasing the oxygen flow rate changes the total amount of air. So how can I set the oxygen concentration in the air as the operating variable?
Add a calculation module so that the nitrogen flow rate plus the oxygen flow rate equals a constant value
Okay, thank you~ The air contains oxygen, nitrogen, and argon. Since I’m learning this on the spot, I set the flow rate of nitrogen to equal the total flow rate minus the flow rates of the other two gases... The amount of argon doesn’t change; I’m not sure if this is correct, haha
