Problems with the adsorption tower
Thread Content
I seek advice from experts: In a pressure swing adsorption (8-tower) system, the pressure in tower B decreased slightly, while the pressure in tower E increased to 1.16 Mpa; pressure equalization should have taken place. However, the pressure in tower E suddenly dropped to 1.03 Mpa, resulting in an adsorption pressure that was 0.1 Mpa lower than that of the other towers after the final pressure adjustment. Which programmable valve is leaking?
Valves connected to it and having a pressure on the other side of their valves that is lower than that pressure are all possible, and can be observed cyclically. The leakage rate can be determined by evaluating it, and by observing the relationship between the pressure curve and valve operation.
