What is the effect of increasing or decreasing the subcycle time on hydrogen purity and hydrogen recovery at high feed rate or low feed rates? what is the capacity factor ?

What is a "subcycle"?

What is the "capacity factor"?

If your PSA feed hydrogen gets contaminated ( Generally with Higher amounts of Carbon monoxide etc ), reducing the PSA adsorption cycle timing is a good option to avoid the breakthrough of the contaminant as the bed gets saturated faster.


In case of normal PSA operation where you want to just ask a "What if" scenario, with the usual hydrogen feed 


- Reducing the adsorption time will lead to a better product quality (unless its already at 99+ purity)
