Problems with PSA operation
Thread Content
Our facility has 12 PSA towers, and one operating cycle consists of 24 steps. I would like to ask: if the setting for T1/T2 is 40 seconds, how long does one operating cycle take? How is this calculated?
12*(T1+T2), I guess
The time it takes for an adsorption tower to go from one state (such as the adsorption state) through various other states (such as pressure equalization, forward desorption, reverse desorption, purging, pressure equalization again, and final pressure increase) before returning to this initial state (i.e., adsorption) is what is commonly referred to as the operating cycle (which can be thought of as moving 360 degrees around a circle, starting from 0 and ending back at 0). Based on the information provided by the poster, its cycle time is 12*(T1+T2) = 960 seconds.
(40+40)*12=960s
