PSA10 to Tower 9 (manual tower switching)
Thread Content
Taking the 10-3-4 cut as 9-2-4 as an example. 10 towers to 9 towers; when switching towers manually, it is done in reverse sequence. After cutting, it operates with 9 towers. It will operate in 9-2-4 mode. Up to the moment just before cutting, each tower followed the 10-3-4 operating rules: adsorption, pressure increase/decrease, forward operation, reverse operation, flushing, and so on; every tower operated in sequence. So, at the moment of cutting, does the operating sequence of each tower change? ?
Are the steps changed in all cases, or only those of the tower behind it?
Of course, there will be changes. Previously, 3 towers were used for adsorption with 4 pressure equalization steps, but after switching to 9-2-4, only 2 towers are used for adsorption. Tower switching is generally done when the pressure is low, during the reverse flow or flushing phase, which results in less fluctuation in the system. In emergency situations, towers can be switched at any time, and the program can be adjusted according to the appropriate procedures! If the Tacheta is in an adsorption state at that time, the fluctuations in the hydrogen desorption gas will be significant; the corresponding sequence of operations will follow the program settings – it mainly depends on your valve status table! That tower has a malfunction!
For ten towers, it depends on which tower you decide to remove, and at what stage you do so! It depends on the situation! If you choose a tower, do you remove it at that stage? Could you please provide the valve status table for the programmable valve?
PSA cannot simply cut down a tower; before doing so, it is necessary to figure out which tower has failed at which step, otherwise even if a tower is cut down, there’s no way to know how to proceed! !
