Why can voltage equalization improve the recovery rate?

I still don’t fully understand why voltage equalization can increase the recovery rate Which sea friend can explain this, please? Thanks :)
The main function of pressure equalization is to recover effective gas from the dead space in the bed while simultaneously recovering pressure, thereby increasing the yield. The pressure equalization process involves connecting the high-pressure tower and the low-pressure tower to achieve pressure balance. During this process, the effective gas inside the high-pressure tower flows into the low-pressure tower, raising its pressure; at the same time, this effective gas is retained within the system. After several rounds of pressure equalization, the remaining gas is removed from the system through processes such as forward discharge, reverse discharge, and flushing – this gas constitutes the lost gas. The loss of effective gas mainly occurs in the steps following the completion of pressure equalization.
I recommend that you take a look at “Pressure Swing Adsorption Operation Design 4” at http://bbs.hcbbs.com/thread-1654047-1-1.html; it discusses the issues related to yield and the number of pressure equalization cycles. Although it’s quite simple, it’s still worth referring to.
In simple terms: the pressure equalization mechanism distributes the high-concentration active components from the adsorption tower to the desorption tower, which is better than having the desorption tower start working from scratch gradually. To put it plainly, it’s not worth a penny
