Control systems for argon fractions in small air separation units

Control systems for argon fractions in small air separation units
The upper tower reflux ratio becomes smaller, the argon fraction rises, and the rise of the argon fraction will accordingly affect the reduction of the amount of medium pressure air, ensuring the stability of the argon fraction. Argon fraction compensation control generally through the pid function fast or variable first fast to control.
