【PSA】Step setting for pressure swing adsorption

In our unit’s pressure swing adsorption process, the adsorption step itself consists of four stages: Adsorption 1, Adsorption 2, Adsorption 3, and Adsorption 4. The reverse operation involves only two stages: Reverse Operation 1 and Reverse Operation 2, while the washing step again comprises four stages. What I want to ask is: what determines the existence of these many different steps? Why are some steps more numerous while others are fewer?
The manufacturer developed a sequence chart to achieve continuous production. Let the experts from Tianyi and West China answer.

Steps 1, 2, 3, and 4 are merely descriptions of the state of the adsorption tower; they were separated by the design company for the purpose of making it easier to organize the procedural steps, but in reality they represent the same state； The duration is adjusted based on the system’s pressure equalization speed, load size, and residual pressure after venting. The above are just personal opinions. :)
Everything is set based on time; the values for T1 and T3 are fixed. All we can adjust is the duration of T2, and the value for T2 is determined by the purity of hydrogen. This is just my personal opinion – if it’s not correct, please don’t criticize me……
The T1 and T3 times are also adjustable.
That’s set by the manufacturer; we can only adjust T2
